It is a transparent, standard-based, criterion-referenced assessment system designed to monitor student achievement of the Oklahoma Priority Academic Student Skills (PASS) adopted by the Oklahoma State Board of Education. Currently, the OCCT includes direct Writing assessments in Grades 5 and 8 and Multiple-Choice (MC) assessments of Reading and Mathematics in Grades 3 through 8; Science in Grades 5 and 8; as well as Social Studies in Grade 5; Geography in Grade 7; and U.S. History, Constitution, and Government in Grade 8.In 2010, the OCCT was administered during the spring. The Writing assessments were administered on February 24th and March 3rd. The Grade 7 Geography and Grade 8 Reading and Mathematics were administered online during an April 12th to May 14th window. The remaining tests were administered during the MC testing window of April 12th to May 7th. The Writing and Multiple-Choice administration windows were extended in 2010 as a result of inclement weather in the state.This technical report outlines the statistical analyses that were carried out in support of the 2010 OCCT. Chapter I provides an overview of the test content and design. Chapter II details the statistical procedures that were carried out in support of the OCCT. These procedures include preliminary item analyses, differential item functioning analyses, calibration and equating, and various miscellaneous analyses. Chapter III presents statewide test results. Chapter IV describes the performance standard setting process and results. Two appendices are provided. Appendix A presents the data review results. Appendix B presents the raw score to scaled score (RS – SS) conversion tables and frequency distribution by grade.The technical information provided in this report is intended for use by all interested in how the test is evaluated, how the scores are interpreted, and the subsequent educational decisions based on the test results. It is assumed that the reader has technical knowledge of test construction and measurement procedures, as stated in Standards for Educational and Psychological Testing (American Educational Research Association, American Psychological Association, National Council on Measurement in Education, 1999).CHAPTER I. OVERVIEW OF THE OCCTThe purpose of the Oklahoma Core Curriculum Test (OCCT) is to fulfill accountability requirements and to provide feedback about student mastery of the knowledge and skills delineated in the Oklahoma Priority Academic Student Skills (PASS) standards. In the spring of 2010, the OCCT assessments were administered to all eligible public school students in Grades 3 through 8. The OCCT includes assessments of Reading and Mathematics in Grades 3 through 8; Writing and Science in Grades 5 and 8; as well as Social Studies in Grade 5; Geography in Grade 7; and U.S. History, Constitution, and Government in Grade 8. All tests were designed to measure the Oklahoma Priority Academic Student Skills (PASS) adopted by the Oklahoma State Board of Education. The 2010 administration of the OCCT was the sixteenth for students in Grades 5 and 8 and the sixth for students in Grades 3, 4, and 7 (Geography only). This was the fifth operational administration of the Reading and Mathematics tests in Grades 6 and 7. Data Recognition Corporation (DRC) worked with the Oklahoma State Department of Education (SDE) to construct OCCT test forms aligned to the PASS standards. Each test form included a set of operational items used to produce student test scores, and a set of embedded field-test items. The Writing assessments included one extended constructed-response (CR) item. The Reading, Mathematics, Science, Social Studies, Geography and History assessments were composed of Multiple-Choice (MC) items only. For each content and grade, there were eight forms consisting of a common set of operational items and a unique set of 10 field-test items. Responses to the operational items were used to produce student scores. Responses to the field-test items were used to evaluate the psychometric properties of these newly developed items for possible inclusion on future forms.The OCCT is an untimed test. The MC tests in Grades 3 – 5 were administered in two sessions. The Writing tests in Grades 5 and 8 and the MC tests in Grades 6 – 8 were administered in one session. With the exception of Grade 7 Geography and Grade 8 Reading and Mathematics, all assessments were administered as paper-and-pencil tests. The Grade 7 Geography and Grade 8 Reading and Mathematics assessments were delivered primarily online, with paper forms available for accommodated administrations and for make-ups. In the following sections, more information is provided on the skills assessed by the OCCT, test development procedures, and the configuration of the tests.1.1 Skills Assessed by the OCCTThe standards assessed by each test can be found at . The OCCT measures all PASS standards except for objectives that cannot be appropriately measured within the limitations of a large scale, Multiple-Choice test. For example, the majority of PASS standards (listening, reviewing, etc.) are not measured in the ELA assessment. Standards not measured by the OCCT must be assessed by local school districts.1.2 Test Development ProceduresThe items used in the operational 2010 OCCT were selected from the SDE-owned pool of items. All items selected had previously been reviewed and approved by Oklahoma content, bias, and sensitivity review committees. These operational items had been field tested during previous administrations. The field-test statistics for these operational items indicated that the items were of acceptable quality.For field-test items embedded in the OCCT, DRC assessment specialists selected field test ready items from SDE's item bank, as well as items newly-developed for 2010. A total of 80 items per content/grade were selected for embedded field-testing. 1.3 Configuration of the Tests Table 1.3.A shows the number of operational and field-test items by content area and grade used in the 2010 operational tests. Also shown is the number of operational items included in the anchor set used for equating the 2010 forms to the previously established reporting scale. For all Multiple-Choice tests, each form contained a core set of operational items common across forms and a unique set of field-test items.Table 1.3.A Number of Operational and Field-test Items by Content Area and GradeContent AreaGradeNumber of FormsNumber of Operational Items per FormaNumber of Operational Items in Anchor SetaNumber of Field-test Items per FormTotal Number of Items per FormTotal Number of Field-test Items Per Grade????????Reading3-885014-18b106080????????Writing5, 8110010????????Mathematics3-884517-20c105580????????Science5, 884516,14105580????????Social Studies586020107080????????Geography784515105580????????U.S. History884515105580a Operational item counts include anchor items. b Anchor counts for Reading tests were 17, 18, 16, 14, 17, and 15 in Grades 3 through 8 respectively. c Anchor counts for Mathematics tests were 20, 19, 18, 18, 17, and 17 in Grades 3 through 8 respectively.

CHAPTER II. STATISTICAL ANALYSISThis section provides an overview of the research and statistical analyses carried out for the 2010 administration of the OCCT. Following the administration of the OCCT, student demographic and item response data were transmitted to DRC’s Psychometric Services (PS) department. PS staff is responsible for analyzing the OCCT test data and producing the scoring tables used for reporting.The analyses of the test data can be broken down into several components: 1) classical item analyses; 2) differential item functioning (DIF) analyses; 3) reliability analyses; 4) calibration and equating; 5) production of scoring tables; and 6) validity analyses. In the following sections, the analysis procedures for each component are described. Separate sections are provided for the Multiple-Choice tests and the Writing tests.2.1 Data Files for Statistical Analysis Preliminary item and DIF analyses and the final calibration/equating for the Multiple-Choice tests were conducted using early-return sample data consisting of approximately 50% of the examinee population. The final item and DIF analyses were conducted using data files that contained 100% of the student data. For the analysis of the Writing tests, the rater-year effect analysis was conducted based on a sample (n = 510) which was randomly drawn from 2007 and rescored in 2010. All other analyses on writing were conducted using the final population data file.2.2 Analysis of the Multiple-Choice Tests2.2.1 Classical Item Analyses Classical item analyses were conducted using DRC’s software, iTEMs (DRC, 2010). The analyses involved computing a set of statistics based on classical test theory for every item in each form. Each statistic is designed to provide empirical information about the characteristics of each item. The statistics estimated for OCCT items are described below. Classical Item Difficulty (“p-value”): This statistic indicates the proportion of examinees in the sample that answered the item correctly. Desired p-values generally fall within the range of 0.30 to 0.90. Occasionally, items that fall outside this range can be justified for inclusion in an assessment based upon other quality indicators (e.g., adequate point-biserial), the educational importance of the item’s content, or to better measure students with very high or low achievement. Item Discrimination (“point-biserial”):This statistic describes the relationship between performance on the specific item and performance on the entire form. Estimated as the correlation between the item score and the total test score, it indicates the extent to which test takers with high test scores tend to answer the item correctly, and those with low scores tend to answer incorrectly. The point-biserial correlation for item i is given by,where is the mean score for those students who answered item i correctly, and and are the mean score and standard deviation for the test form, and is the item difficulty for item i.Items with negative or low correlations can indicate problems with the item (e.g., incorrect key, multiple correct answers or unusually complex content), or can indicate that students have not been taught the content. Examination of Empirical Item Response Curves (EIRC):iTEMs provides graphical displays of student performance on each item. In the MC item plots, the x-axis represents the criterion score level (the total number-correct score) and y-axis represents the percentage of examinees choosing the response option. Each response option is plotted, representing the percentage of examinees that chose that particular option by ability level. One would expect the curve for the correct option to increase as ability level increases. These graphs were reviewed by DRC psychometricians.Percentage of Students Omitting or not Reaching an Item:This statistic is useful for identifying issues related to testing time and item/test layout. Testing time issues do not exist for the OCCT’s as they are untimed. However, if the omit percentage is greater than 5% for a single item, this could be an indication of an item/test layout problem. For example, students might accidentally skip an item that follows a lengthy stem.For the OCCT operational and field-test analyses, a series of flags were created in order to automatically identify items with performance characteristics that are at times considered unusual. The following flagging criteria were applied to all items tested in spring 2010: P-value less than .30 or greater than .90; The percentage choosing an “incorrect” option is equal to or greater than the percentage choosing the correct option;The percentage of students selecting any of the “incorrect” options is larger than 30%;Point-biserial correlation is less than .30 for the correct answer;Any of the “incorrect” answer options (distractors) with a positive point-biserial;Percentage of test takers omitting the item is greater than 5%.After the operational administration, the early-return data were used to conduct preliminary analyses to verify the accuracy of the scoring keys and to obtain an early indication of how items were functioning. Content specialists examined all flagged items to ensure that the items were correctly keyed.Upon receipt of the complete student data, the items were further scrutinized during a final round of classical item analysis. After content specialist’s review and verification, item statistics were prepared for uploading to the item bank.Summary statistics describing the difficulty and discrimination of items comprising the operational forms are given in Table 2.2.A. Results are combined across test forms for a given grade and content area because the operational items were the same for all test forms. Differential item functioning (DIF) flags and reliability indices (alpha, SEM, and stratified alpha) are also provided. These statistics are described in the sections that follow.Table 2.2.A Classical Item and Test Analyses Summary for the Operational FormsContent Area/GradeGradeN ItemsAlphaSEMStratified Alphap-valuePt-BiserialFlagged Item CountMeanSDMeanSDStatsaDIFReading3500.892.900.890.690.140.400.071004500.892.830.890.710.140.400.07705500.892.700.890.740.140.410.071026500.902.990.900.660.120.410.08827500.872.880.870.700.150.370.071528500.882.830.880.720.150.380.08155Mathematics3450.902.580.910.740.130.430.08504450.892.620.890.720.150.420.07805450.892.770.890.670.140.420.08826450.892.810.900.670.110.420.08507450.872.820.870.650.160.390.06908450.882.820.880.680.110.400.0791Science5450.882.720.880.690.150.400.061108450.862.840.860.650.160.380.07142Social Studies5600.893.410.890.600.140.370.08200Geography7450.862.900.860.640.130.380.08164U.S. History8450.892.880.890.620.130.410.0790aClassical item statistics flagged using the criteria from the bulleted points above.As shown in Table 2.2.A, the mean item difficulties of the tests across content/grade ranged from 0.60 to 0.74, and the mean point-biserial correlations ranged from 0.37 to 0.43. The internal consistency reliability estimates (coefficient alpha) of all tests were high, ranging from 0.86 to 0.91. The stratified alpha coefficients were almost identical to the alpha (after rounding). The SEMs ranged from 2.58 to 3.41. Table 2.2.A also shows that a small number of operational test items were flagged for out-of-range statistics and/or C category DIF. Items flagged for out-of-range statistics were scrutinized by content experts to verify the accuracy of the items in the test books, to verify keys, and to judge whether items were performing as expected. All items flagged for out-of-range statistics were found to be accurate, correctly keyed, and performing in a satisfactory manner with respect to content. DIF results for the operational items are discussed in the next section.The results of the classical item analysis for the field-test items are presented in Table 2.2.B. Field-test items with extreme difficulty values, low point-biserials or poorly functioning distractors, and/or DIF were flagged for review by content experts. The number of items flagged for poor statistics ranged from 34 to 59 per content/grade. A very small number of items were flagged for DIF. All flagged items were evaluated at a Data Review Meeting and individual decisions were made about each item. Items rejected during Data Review will not be eligible as operational items in the future test administrations. Items accepted with revisions will be returned to the item bank and will be revised and re-field tested as necessary. The results of the Data Review are presented in Appendix A.Table 2.2.B Item Analyses Summary for Field-test ItemsContent AreaGradeSample SizeN Itemsp-valuePt-BiserialFlagged Item Count RangeMeanSDMeanSDStatsaDIFReading35323-5535800.610.170.360.10302?44800-5452800.620.160.340.10283?54259-5493800.620.170.340.12270?64692-5398800.570.170.320.12291?74176-5255800.650.160.340.11281?84939-5526800.650.160.300.11395Mathematics35435-5603800.750.160.360.10313?44953-5511800.640.160.360.10321?54407-5515800.580.230.330.13452?64766-5410800.550.200.310.13361?74198-5267800.540.200.300.10452?84844-6058800.590.160.330.11321Science54453-5574800.560.180.300.11361?84375-5220800.550.190.300.11403Social Studies54985-5952800.470.140.290.12450Geography75157-8292800.530.170.270.13471History84798-5515800.500.150.330.13302aOut-of-range classical item statistics2.2.2 Differential Item Functioning AnalysesOne of the goals of test development is to assemble a set of items that provides an estimate of a student’s ability that is as fair and accurate as possible for all groups within the population. DIF statistics are used to identify items that groups of students with the same underlying level of ability have different probabilities of answering correctly. If the item is differentially more difficult for an identifiable subgroup when conditioned on ability, the item may be measuring something different from the intended construct. However, it is important to recognize that DIF-flagged items might be related to actual differences in relevant knowledge or skills (item impact) or a statistical Type I error (a “false positive”). As a result, DIF statistics are used to identify potential sources of item bias. Subsequent review by content experts and bias/sensitivity committees is required to determine the source and meaning of performance differences.For the OCCT, the Mantel-Haenszel (MH) procedure ADDIN EN.CITE <EndNote><Cite><Author>Mantel</Author><Year>1959</Year><RecNum>198</RecNum><MDL><REFERENCE_TYPE>0</REFERENCE_TYPE><AUTHORS><AUTHOR>Mantel, N.</AUTHOR><AUTHOR>Haenszel, W.</AUTHOR></AUTHORS><YEAR>1959</YEAR><TITLE>Statistical aspects of the analysis of data from retrospective studies of disease</TITLE><SECONDARY_TITLE>Journal of the National Cancer Institute</SECONDARY_TITLE><VOLUME>22</VOLUME><PAGES>719-748</PAGES></MDL></Cite></EndNote>(Mantel & Haenszel, 1959; Holland & Thayer, 1988) was used to estimate DIF statistics for subgroups of interest defined by the SDE for NCLB accountability. Comparison groups were based on gender (female versus male), ethnicity (Hispanic versus White, American Indian versus White, African American versus White, Asian versus White, Pacific Islander versus White), and economic status (students who are economically disadvantaged as indicated by participation in a free and reduced-price school lunch program versus students who are not economically disadvantaged). Items with statistically significant differences in performance were flagged for possible biased or unfair content that was undetected in earlier fairness and bias reviews. DIF analyses results were not considered as valid when the sample size for either the reference group (i.e., male, White, not economically disadvantaged) or focal group (i.e., female, Hispanic, American Indian, African American, Asian, Pacific Islander, economically disadvantaged) was less than 300 and the sample size for the two groups combined was less than 700.The MH procedure is one of the more commonly used methods to detect DIF. This method uses contingency tables to compare the probability of success on each item for the studied groups of interest after matching on overall ability (i.e., total test score). The common odds ratio is estimated across all categories of matched examinee ability. The resulting estimate is interpreted as the relative likelihood of success on a particular item for members of two groups when matched on ability. As such, the common odds ratio provides an estimated effect size where a value of unity indicates equal odds, and thus no DIF ADDIN EN.CITE <EndNote><Cite><Author>Dorans</Author><Year>1993</Year><RecNum>199</RecNum><MDL><REFERENCE_TYPE>7</REFERENCE_TYPE><AUTHORS><AUTHOR>Dorans, Neil J.</AUTHOR><AUTHOR>Holland, Paul W.</AUTHOR></AUTHORS><YEAR>1993</YEAR><TITLE>DIF detection and description: Mantel-Haenszel and standardization</TITLE><SECONDARY_AUTHORS><SECONDARY_AUTHOR>Holland, Paul W.</SECONDARY_AUTHOR><SECONDARY_AUTHOR>Wainer, Howard</SECONDARY_AUTHOR></SECONDARY_AUTHORS><SECONDARY_TITLE>Differential item functioning</SECONDARY_TITLE><PLACE_PUBLISHED>Hillsdale, NJ</PLACE_PUBLISHED><PUBLISHER>Lawrence Erlbaum</PUBLISHER><PAGES>35-66</PAGES></MDL></Cite></EndNote>(Dorans & Holland, 1993). The common odds ratio () is estimated as where Rrs = the number of examinees in the reference group who answer the item correctly,Wfs = the number of examinees in the focal group who answer the item incorrectly,Rfs = the number of examinees in the focal group who answer the item correctly,Wrs = the number of examinees in the reference group who answer the item incorrectly, Nts = the total number of examinees.The odds ratio takes on values from 0 to infinity and is interpreted as the average factor by which the odds that an examinee of the reference group will answer an item correctly exceed that of a member of the comparable focal group. The statistical test is Ho: = 1, where is a common odds ratio assumed equal for all matched score categories s = 1 to S. Values less than unity indicate DIF in favor of the focal group, a value of unity indicates the null condition, and a value greater than one indicates DIF in favor of the reference group. The associated MH 2 is distributed as a chi-square random variable with 1 degree of freedom. As an index of magnitude, the odds ratio is frequently transformed to a delta scale given by MH D-DIF = -2.35 ln () where negative values indicate DIF in favor of the reference group and positive values favor the focal group. A classification scheme puts items into three DIF categories on the basis of a combination of statistical significance and magnitude (absolute value) of MH D-DIF (Zwick and Ercikan, 1989):A-items or negligible DIF: MH D-DIF is not statistically different from 0 (at the .05 level) or its absolute value is less than 1 delta unit;B-items or intermediate DIF: MH D-DIF is statistically different from 0 (at the .05 level) and its absolute value is at least 1 but less than 1.5 or an absolute value of at least 1 but not significantly greater than 1 (at the .05 level);C-items or large DIF: MH D-DIF is statistically different from 1 (at the .05 level) and its absolute value is at least 1.5.Items classified as B+ or C+ tend to be easier for members of the focal group than for members of the reference group whose total scores on the test are like those of the focal group. Items classified as B- or C- tend to be harder for members of the focal group than for members of the reference group whose total scores on the test are like those of the focal group. Items classified in category C were sent to test development staff for review. They were asked to consider any identifiable characteristics that may have contributed to the differential item functioning. The items were then submitted to the SDE for further review. Table 2.2.A shows that a small number of operational items were flagged for C DIF. These items were reviewed by DRC’s content experts. Recommendations were made by DRC on whether to remove an item with C DIF from scoring or not. SDE content experts further reviewed these items and made the final decision. As a result, no items were dropped in the 2010 administration. DIF analysis was also conducted on the field tests. Items with C DIF were flagged and reviewed by SDE and DRC’s content experts at the data review meeting. Appendix A reports the items rejected due to DIF and/or other poor statistics. 2.2.3 Item Calibration and Equating The purpose of item calibration and equating is to create a common scale for expressing the difficulty estimates of all the items across forms within a test. The scale is initially defined so that the examinees used in the calibration will have a mean score of 0 and a standard deviation of 1. It should be noted that the metric of this scale is often referred to as the “theta” metric. This scale is not used for reporting purposes because its values typically range from –3.0 to +3.0, which is a scale that is not easily understood. Therefore, following calibration and equating, the scale is usually transformed to a reporting scale that can be understood more easily by students, teachers, and other stakeholders. The three-parameter logistic (3PL) model was used to calibrate the OCCT test items. The 3PL model expresses the probability that a person with ability will respond correctly to item j as a function of item and ability parameters:where:Ujis the response to item j, 1 if correct and 0 if incorrect;ajis the slope parameter of item j, characterizing its discriminating power;bjis the threshold parameter of item j, characterizing its difficulty; andcjis the lower asymptote parameter of item j, reflecting the chance that students with very low proficiency will select the correct answer, sometimes called the “pseudo-guessing” level.The parameters estimated for the 3PL model were discrimination (a), difficulty (b), and the pseudo-guessing level (c). All item response theory (IRT) based analyses were conducted using PARSCALE (Muraki and Bock, 2003).For each operational test, items were calibrated separately by content and grade. The calibrations were examined to assess the quality of the parameter estimates and model-data fit. Items were flagged for:a-parameters less than 0.3 or greater than 2.3b-parameters less than -3.5 or greater than 3.5c-parameters greater than 0.35 for 4-option itemsNot calibrated due to biserial correlations less than 0.10Data model fit is “bad.” (This criterion varies depending on the response n-count.) Flagged items were reviewed to determine whether they should be excluded from scoring. No items in the 2010 OCCT were excluded from scoring because of IRT results.After the final set of item parameter estimates were established, the scales for the 2010 operational tests were linked to the reporting scale using the test characteristic curve (TCC) method described by Stocking and Lord (1983). The Stocking and Lord procedure involves finding a linear transformation that will minimize the sum of squared differences between two TCCs generated from two sets of anchor item parameters.Embedded in the 2010 OCCT were sets of anchor items that had served as operational items in the 2009 OCCT. These items were positioned so their sequences were very similar to that in the prior year. The sets were chosen for being both content and statistically representative of the entire test to ensure an accurate equating result. The anchor set is mostly unique for each testing cycle, though some items may be used as anchors for multiple administrations. Repeated use of an item creates the risk of overexposure and is avoided in practice. Table 2.2.C summarizes the number of anchor items per test. The parameters for the 2009 items were expressed on the reporting scale. These 2009 item parameters served as a reference item set and were used with their 2010 counterparts and the Stocking and Lord procedure to find transformation constants. These constants were used to transform the 2010 item parameters so that they were expressed on the reporting scale. Once this was done, the transformed parameters were used to generate raw score to scaled score conversion tables.

For each content/grade, field-test items were calibrated with the operational items. Resulting field-test parameters were placed on the OCCT reporting scale using the operational items as the anchor set in the Stocking and Lord procedure. 2.2.4 Raw Score to Scaled Score Conversion Since 2005, the OCCT scaled scores have been produced using a number-correct scoring procedure that is based on IRT. This procedure produces maximum-likelihood trait estimates for each obtainable raw score, except for raw scores at chance or below-chance levels and the perfect raw score. It is conventional to assign scaled scores to at and below-chance level raw scores and perfect raw scores using a rational, but not necessarily maximum likelihood, procedure. These values are called the lowest obtainable scaled score (LOSS) and the highest obtainable scaled score (HOSS). The LOSS and HOSS values assigned to all OCCT operational tests were 400 and 990, respectively.For all MC tests, the OCCT score scale uses a three-digit integer that spans a range from 400 (LOSS) to 990 (HOSS). The Proficient cut score for reading and Mathematics and the Satisfactory cut score for science and social studies is 700 for all tests. The raw-score to scaled-score conversion tables are provided in Appendix B. 2.2.5 Test Score ReliabilityTest score reliability focuses on the extent to which differences in test scores reflect true differences in the knowledge, ability, or skills being tested rather than random fluctuations. The variance in the distributions of test scores, essentially the differences among individuals, is partly due to real differences in the knowledge, skills, or ability being tested (called true score variance) and partly due to random factors that cause variability in examinee performance (called error variance). The number used to describe reliability is an estimate of the proportion of true score variance to total variance. Several different ways of estimating this proportion exist. Coefficient AlphaWhen the goal is to estimate the precision of a set of test scores from a single administration, a measure of internal consistency (sensitive to random errors associated with item content sampling) is frequently used to estimate reliability. For the OCCT, the measure of internal consistency called coefficient alpha (Cronbach, 1951) was used to estimate the reliability of the test scores. The formula for coefficient alpha is given bywhere k is the number of items on the test, is item score variance summed over all items, and is observed-score variance.Internal consistency measures apply only to the test form being analyzed. They do not take into account form-to-form variation due to equating limitations, nor are they sensitive to day-to-day variation due, for example, to state of health or testing environment. Reliability coefficients may range from 0 to 1. The higher the reliability coefficient for a set of scores, the more likely it would be for individuals to obtain very similar scores over replicated testing (e.g., using the same number of items, sampling same content domain(s), etc.). The internal consistency of the multiple-choice test scores are reported in Table 2.2.A for all examinees and in Tables 3.3 – 3.21 by demographic subgroup.When a test contains different components (e.g., content standards), the stratified alpha coefficient can provide a more accurate estimate of the overall test reliability (Qualls, 1995). The stratified alpha coefficient is calculated by ,where, is the variance of the total test scores; is the variance of scores for each test component (i.e., content standards in this case); and is the coefficient alpha reliability for scores from content standard J. The stratified alpha coefficients for the multiple-choice test scores are reported in Table 2.2.A for all examinees and in Tables 3.3-3.21 by demographic subgroup. Standard Error of MeasurementThe standard error of measurement (SEM) is the standard deviation of the errors of measurement that is associated with the test scores of a specific group of test takers. In Classical Test theory (CTT), an overall SEM can be estimated as a function of the standard deviation of observed scores and test reliability coefficient:where SEM is standard error of measurement, sx is standard deviation of observed scores, and rxx is a coefficient of reliability.The SEM is particularly useful in determining the confidence interval (CI) that captures an examinee’s true score. Assuming that measurement error is normally distributed, it can be said that upon infinite testing replications, approximately 95 percent of the CIs of 1.96 SEM around the observed score would contain an examinee’s true score (Crocker & Algina, 1986). For example, if an examinee’s observed score on a given test equals 15 points, and SEM equals 1.92, one can be 95% confident that the examinee’s true score lies between 11 and 19 points (15 3.76 rounded to the nearest integer). Table 2.2.A provides the SEM for each multiple-choice test.Conditional Standard Error of MeasurementFrom the IRT framework, a standard error of measurement can be estimated for each measured ability. Thus, it is often referred to as a conditional standard error of measurement (CSEM). The expected a posterior estimation of CSEM proposed by Kolen, Zeng, and Hanson (1996) was used for the OCCT. The calculation of CSEM can be expressed as: where is the scaled score for a particular number correct score X; is the IRT ability scaled value conditioned on; and is the probability function that is computed using a recursive algorithm given by Thissen, Pommerich, Billeaud, and Williams (1995). For the operational OCCT, CSEMs were provided for each obtainable scaled score (see Appendix B).Reliability of Performance-Level Classification DecisionsStudent performance on the OCCT is classified into one of four achievement levels using cut scores adopted by the SDE. Table 2.2.D provides the cut score for each achievement level and the CSEM associated with each cut score in 2010.

The reliability of 2010 achievement-level classification decisions was assessed using the computer program BB-CLASS (Brennan, 2004), which provides two statistics that describe the reliability of classifications based on test scores (Livingston & Lewis, 1995). More specifically, information from an administration of one form is used to estimate the following: Decision Accuracy, which describes the extent to which performance-level classification decisions based on the administered test form would agree with the decisions that would be made on the basis of a perfectly reliable test (i.e., meaning if it was possible to know each examinee’s true score). Decision accuracy answers the question: How does the actual classification of test takers, based on their single-form scores, agree with the classification that would be made on the basis of their true scores, if their true scores were somehow known?Decision Consistency, which describes the extent to which classification decisions based on the administered test form would agree with the decisions made if a parallel alternate form had been administered. Decision consistency answers the question: What is the agreement between the classifications based on two non-overlapping, equally difficult forms of the test?For each performance level and test, true scores and single-form scores on forms parallel to the one actually given are estimated following the Livingston and Lewis (1995) method. The decision accuracy is estimated using an estimated joint distribution of reported performance level classifications on the current form of the exam and the performance-level classifications based on the true score. Decision consistency is estimated using an estimated joint distribution of reported performance-level classifications on the current form of the exam and performance-level classifications on the parallel alternate form. In each case, the proportion of performance-level classifications with exact agreement is the sum of the entries in the diagonal of the contingency table representing the joint distribution. Reliability of classification at each performance-level cut score is estimated by collapsing the joint distribution at the passing score boundary into a 2-by-2 table and summing the two entries. Table 2.2.E provides the results for decision accuracy and consistency analyses that were conducted at the Limited Knowledge, Proficient/Satisfactory, and Advanced cut scores, and for the four performance levels (total). It should be noted that decision accuracy and consistency indices for the four performance levels should be lower than those for each cut, as shown in Table 2.2.D. This is not surprising since classification using four levels would allow more opportunity to change achievement levels. Hence there would be more classification errors in the four achievement levels, resulting in lower consistency indices.For the OCCT, a PASSing score is one that meets or exceeds the Proficient/Satisfactory cut score. Across all tests, the decision accuracy of the Proficient/Satisfactory cut scores ranged from 0.89–0.94 and decision consistency ranged from 0.85–0.92.These results indicate that at least 89% students meeting or exceeding the Proficient/Satisfactory cut score would receive the same PASS/fail classification if their true scores were known. If a parallel test were administered, at least 85% or more of students meeting or exceeding the Proficient/Satisfactory cut score would be classified in the same way.Table 2.2.E Estimates of the Reliability of Decisions for Specified Cut Scores aContent AreaGradeDecision AccuracyDecision ConsistencyLimited KnowledgeProficient/SatisfactoryAdvancedTotalLimited KnowledgeProficient/SatisfactoryAdvancedTotalReading30.950.910.980.840.930.880.970.7840.940.910.970.820.910.870.960.7650.950.910.910.770.930.870.900.7160.940.910.940.800.920.880.930.7370.930.900.910.750.900.860.880.6780.940.910.910.770.920.870.880.69Mathematics30.960.920.910.790.940.890.880.7140.950.910.920.780.920.870.890.7050.950.910.910.770.920.870.870.6860.930.910.910.760.900.870.870.6770.920.890.900.720.880.850.870.6480.930.900.910.750.900.860.870.66Science50.980.940.900.820.970.920.860.7680.980.940.920.830.960.910.880.77Social Studies50.940.910.920.780.920.880.890.70Geography70.980.920.910.810.970.890.870.74History80.950.910.930.790.930.880.910.72a: The analysis was based on the final data files with students who took the standard OCCT. 2.2.6 ValidityAs noted in the Standards for Educational and Psychological Testing, “validity refers to the degree to which evidence and theory support the interpretations of test scores entailed by the proposed uses of the tests” (AERA, APA, & NCME, 1999, P.9). Content representativeness considerations, item bias (i.e., DIF) analysis, and correlations among content standards are often used as sources of validity evidence.Each test’s blueprint specifies the proportion of items that should be devoted to any given content unit. The blueprint is used as a guide by test developers when assembling a test from a pool of candidate items that are classified by content unit. Validity evidence related to test content is bolstered to the extent that the numbers of items allocated to each PASS Standard/Objective reflect what is specified by the test blueprints. Tables 1.2 to 1.18 in Chapter 1 provide content validity evidence by standard for the 2010 OCCT.Differential item functioning with respect to gender, ethnicity, and economic status helps address construct-irrelevant variance, which represents an important threat to the validity of achievement tests. As noted in the section of Differential Item Functioning Analyses, field-test items are screened and reviewed for DIF by SDE content specialists. Only items approved by SDE are eligible for operational use. DIF analyses were also conducted on the operational items. After SDE and DRC’s content specialists’ review, no item was dropped from the operational tests. The number of operational and field-test items with C DIF were reported in Tables 2.2.A and 2.2.B.Intercorrelations among standards provide evidence of convergent test validity. The analyses were performed by summing the obtained raw score points for each standard and then correlating the subtotals associated with each standard. Standards with low point totals, e.g., less than five, usually have markedly attenuated coefficients, meaning that they will be spuriously low in magnitude. Tables 1.3.B to 1.3.R list the numbers of items associated with each standard. The correlations among standards are reported in the left corner of Tables 2.2.F through 2.2.V. The correlations corrected for attenuation are reported in the right corner of Tables 2.2.E through 2.2.U. Correcting for attenuation adjusts the correlation between the two measures to account for the unreliability of both. Although the theoretical upper bound for a correlation is 1.0, disattenuated correlations can be greater. This is often seen in practice when the correlations are relatively high and the reliabilities relatively low. However, two underlying factors should be noted. The first is that sample statistics are being used to estimate population parameters. The second, and likely more prevailing issue, is that something akin to a “design misspecification” occurs. The internal consistency reliability indices used for the OCCT likely do not capture all the sources of random error in the test scores, and, as such, might over estimate reliability. One might also postulate potential negative biases (e.g., lack of item homogeneity due to multidimensional content standards). Thus, it is possible that any given tabled disattenuated correlation may be too high, or too low, depending on which bias prevails. Also note that the correlations between standards and total test are spuriously inflated given they have items in common.Given that none of these tests have perfect reliabilities (equal to one), the disattenuated correlations are somewhat higher than the correlations. Disattenuated correlations less than 1.0 suggest that the different strands are measuring slightly different aspects of the constructs. Values around 1.0 suggest that the same or very similar constructs are being measured.Table 2.2.F Standards Intercorrelation: Grade 3 Reading?ReadingVocabularyComprehension/Critical

Students at Grades 5 and 8 were given one operational writing prompt. The Grade 5 operational prompt was field-test prompt #7 in 2007; the Grade 8 operational prompt was field-test prompt #9 in 2007. The following sections describe the statistical analyses conducted to place the 2010 operational writing prompts on the scale established in 2006. 2.3.1 Prompt Scoring FormulaThe writing score is a weighted composite of five analytic scores that focus on specific domains of writing skills. These skills are listed in Table 2.3.A. Each student’s response to a prompt is read by two independent raters; the raters’ scores for each domain are averaged. The domain scores range from 1 (the lowest score) to 4 (the highest score). The raw writing score is calculated as a weighted composite of the average of two independent ratings for each of the five analytic traits: Raw Composite Score (RCS) = 15*(0.30*ID + 0.25*OUC + 0.15*WC + 0.15*SP + 0.15*GUM)Table 2.3.A Weights Assigned to Writing Analytic TraitsWriting Analytic TraitsWeightIdeas and Development (ID)30%Organization, Unity, and Coherence (OUC)25%Word Choice (WC)15%Sentences and Paragraphs (SP)15%Grammar, Usage, and Mechanics (GUM)15%2.3.2 Statistical Adjustments to Scale the Writing ScoresThe baseline for each grade’s operational writing scale was 2006. To place the 2010 operational prompts on the 2006 scale, transformation constants were obtained to adjust RCS scores for prompt difficulty and for rater-year effects relative to a target distribution. All calculations were performed on the RCS prior to rounding. For reporting, the scaled composite scores (SCS) were then rounded to the nearest integer between 15 and 60.Adjustment for Prompt Difficulty and Rater-Year Effects For each of the 2007 field-test prompts, ETS provided a set of unique transformation constants to adjust for both prompt difficulty and rater-year effects. Based on ETS’ report, OCCT Writing: Scaling the 2007 Field-Test Prompts (ETS, 2007), the following equation was used to adjust the 2010 raw composite scores ():.Where represents the scaled composite score after adjusting for the 2007 prompt difficulty and rater-year effects; and are the additive and multiplicative constants (Grade 5: = -0.647451 = 1.023409; Grade 8:= -1.572272 = 1.043021).Adjustment for Rater-Year EffectsIn 2010, DRC performed a rater drift study similar to the one conducted by ETS in 2007 to adjust for the rater-year effects. DRC’s Performance Assessment Services (PAS) staff randomly pulled 510 student responses from 2007 for each grade’s prompt and distributed these into the current administration scoring throughout the entire scoring timeframe. The student responses were pulled by lithocode and were only the valid scored responses (i.e., no condition codes such as off-topic present). 2010 scorers then rescored these papers. The lithcodes randomly pulled by PAS were provided to EIS for generating the data files for Psychometric Services (PS) department. The 2010 rater-year effect constants, and , were determined by using the means () and standard deviations () of the 2007 raw composite scores and the 2010 rescored raw composite scores () as calculated below for each grade: The formula for the 2010 rater-year effects adjusted score is:Once the transformation constants are applied to the 2010 rescored raw composite scores, the mean and standard deviation of the adjusted 2010 scores should be the same as the 2007 mean and standard deviation. A Compound AdjustmentFollowing the calculation of the 2010 transformation constants, compound adjustments were made to the 2010 operational raw composite scores. The generic formula for producing the final 2010 scaled composite score () is: To simplify the calculation, transformation constants for each of the Grades 5 and 8 were calculated as below:The following formula was used to calculate the final scaled composite scores. The calculated values are rounded to the nearest whole integer. Resulting values outside of the 15-60 range are set to the nearest bound. The scaled composite score will be converted to the performance level using Table 2.3.B.

Table 2.3.C provides the sample means and standard deviations used to calculate the transformation constants for each grade. The results indicate that sampled students in both grades had lower 2010 prompt scores. Because the responses scored were the same across the two years, this indicates that the raters were more strict in 2010.Table 2.3.C Sample Means and Standard Deviations Used for Calculating ConstantsGradeStatisticRaters200720105N508508MIN1515MAX6060MEAN*42.8741.07STD*9.028.418N509509MIN1515MAX6060MEAN*44.3641.26STD*7.647.29*Tabled values are rounded for display purposes.

Transformation constants are provided at the bottom of the Tables. The 2008 and 2009 score distributions are also provided for comparison. Relative to no adjustment and the ETS only adjustment, the DRC and ETS compound adjustment led to higher mean scores at both grades.

The average of the two ratings was used for the calculation of the final composite score. Consistency between the two ratings was evaluated with the following statistics: Percentage of exact agreement between raters Percentage of adjacent agreement between raters Correlation between ratings 1 and 2Table 2.3.F provides a summary of the rater-agreement analysis for the Grade 5 and Grade 8 operational prompts. Included are the mean and standard deviation of assigned ratings, the percentage of exact and adjacent ratings, and the correlation between ratings. In Grade 5 writing, the exact agreement rate ranged from 69% to 75%, and the sum of exact plus adjacent agreement rates ranged from 99% to 100%. For Grade 8 Writing, the exact agreement rate ranged from 73% to 79%, and the sum of the exact plus adjacent agreement rates was 100%. The correlations between ratings ranged from 0.63 to 0.67 in Grade 5 and 0.60 to 0.66 in Grade 8. In general, the raters were fairly consistent in each domain.Table 2.3.F Inter-rater Agreement for Operational Writing PromptsGradeDomainaNRating 1Rating 2Percent AgreementCorrbMeanSDMeanSDExactAdjacentExact+Adjacent5ID 448782.790.612.790.6175251000.64OUC 448782.660.642.660.647326990.65WC 448782.800.622.790.6273261000.63SP 448782.780.712.770.707029990.66GUM 448782.880.712.870.7169311000.678ID 420152.850.582.840.5875251000.63OUC 420152.830.582.820.5876241000.63WC 420052.930.522.910.5279211000.60SP 420152.840.612.830.6175251000.66GUM 420152.830.612.830.6173271000.63a ID=Ideas and Development; OUC=Organization, Unity, and Coherence; WC=Word Choice; SP=Sentences and Grammar; GUM=Grammar, Usage, and Mechanicsb Pearson correlation between first and second ratingsCHAPTER III. STATE RESULTSIn this section, performance on the OCCT is summarized for the participating Oklahoma student population and for demographic subgroups. All reported results are based on valid scores on the 2010 forms in the final student data received by June 24, 2010. These data differ from the analysis data in several ways: corrections were made to student and school information, invalidations and missing data issues were resolved, and all students who took the standard, but not the equivalent and Braille, OCCTs were included. Thus, final counts of examinees by test differ somewhat from samples used for item and test analysis.As described in Chapter II, prior to the release of student reports, raw scores were converted to a reporting scale metric. Raw scores on the Multiple-Choice tests were converted to scaled scores using the conversion tables provided in Appendix B. For the Writing tests, analytic scores were converted to composite scores using the formulas provided in the previous section. Achievement level scores were assigned as well using the SDE-established OCCT cut scores. The means and standard deviations of students’ raw scores and scaled or composite scores are shown in Table 3.1. Table 3.2 provides the percentage of students in each achievement category in 2008, 2009 and 2010. Tables 3.3 to 3.21 provide test results by demographic subgroups. Tables B.1 through B.19 provide the raw score, scaled score, CSEM, achievement level, and frequency distributions for each OCCT test.Table 3.1 Means and Standard Deviations of Students' Raw Scores and Scaled ScoresContent AreaGradeValid NRaw ScoresScaled ScoresMeanSDMinMaxMeanSDMinMaxReading34373734.48.7150734.681.840099044302135.68.6250720.173.740099054251037.28.2050726.678.940099064234333.29.3150720.978.040099074088735.18.0350728.170.840099084026435.88.1050740.081.9400990Mathematics34441433.18.3145736.889.440099044370832.48.0045734.490.040099054293830.48.4045729.484.240099064260230.38.6045719.776.140099074103129.37.7045723.779.140099084021430.68.2145728.183.8400990Science54345731.27.8045775.372.240099084110929.17.6045772.068.5400990Social Studies54660435.910.5060731.676.2400990Geography74463429.07.8245775.387.8400990History84388528.18.6145733.181.6400990Writing54487041.57.7156043.78.2156084200542.77.0156046.27.41660a Mean writing composite scores are reported.Table 3.2 presents the percentage of students scoring in each of the four achievement levels for all students for the current year and the past two years.

a Weighted composite scoresCHAPTER IV. PERFORMANCE STANDARDSPerformance standards represent the criteria which specify a minimum score a student must achieve on the statewide assessment to be placed into a given performance level. In Oklahoma, four performance levels (i.e., unsatisfactory, limited knowledge, satisfactory, and advanced) were previously established for grades 5 and 8 in 2001, for grades 3 and 4 in 2005, and for grades 6 and 7 in 2006. However, to increase rigor by raising standards for grades 3 through 8 student’s achievement on the OCCT as a means to be more competitive at the national and international levels, to vertically align proficiency expectations for students on the OCCT tests across grades 3 through 8, and to align student expectations on the OCCT more closely with student expectations for the National Assessment of Educational Progress (NAEP), revised performance standards (unsatisfactory, limited knowledge, proficient, and advanced) for reading and mathematics were established in 2009. The workshop to set new academic achievement level cutpoints for grades 3 through 8 in reading and mathematics was held June 15-18, 2009 in Oklahoma City. Thirty seven educational stakeholders from Oklahoma participated in recommending cut scores for the OCCT. Committee members were primarily selected to span grades 3 through 8, although a small number of higher education teachers and those from the business community who are knowledgeable of education in Oklahoma were also selected. The standard setting method known as the Bookmark procedure (Lewis, Mitzel, & Green, 1996), which is the same procedure used in the previous setting of performance level cut scores in reading and mathematics for grades 3 through 8, was employed. The details of the standard setting materials, procedures, methods, and results were reported in the OCCT Standard Setting: Technical Report (SDE, 2009). Table 4.1 summarizes the final scaled score ranges for the achievement levels.
