Re-release of the 2006 Element 2 Technician Class Question Pool
February 6, 2006
To all i nterested parties: The QPC stri ves to maintain the highest standards of accuracy in the question pools provided by this committee, but unfortunately, as in many human endeavors, perfection is an elusive goal. A few additional errors were discovered in the 2006 Element 2 pool after the initial release. Most of these errors were simple typographic problems, but in at least 3 cases the errors were si gni fi cant enough that the QPC decided to remove the entire questi on from the pool. In 3 more cases, a question was substantially re-worded.
Accordingly, the 2006 Element 2 pool is being re-released to the public on this date. Previous versions should not be used in any form, and should be di scarded enti rely. Only the version dated February 6, 2006 is to be used. Hopefully, no additional errors will be discovered, but if that should happen, then any subsequent changes will be handled by deletion of the affected question.
The Questi on Pool Committee apologizes to all users for this second release of the questi on pool and any inconvenience it might have caused.
The following questi ons have been removed. Subsequent questions in the affected sections are not to be renumbered.
T3B11 T5D06 T6B09 T7A08
