Criteria for “Revisiting” Test.
• Did you locate the correct response and if so where was it found? (page number & paragraph within text, web site(s) used)
• Is your explanation accurate, demonstrating that you understand where your error was made?
• Are your responses legible on the document or an attached sheet of paper.
