Response Data

Establishing Item Statistics for New Examinations

In addition to overall norms, the Institute also produces item statistics for the items that appear on released exams. For this process, we need student performance data on each item. Many testing centers provide class "roll-up" data for items, but this data cannot be aggregated with other schools, so our need is at the individual student level.

National norms will be sent to every examiner supplying data as soon as norms are computed. In addition, a comparison report showing your school performance as compared to the calculated norm is sent along with the released norm sheet to each school that participates.

The report forms are in .pdf format to preserve their original format. You will need the latest Adobe Acrobat Reader to view the file. You can download the free Acrobat Reader directly from Adobe here:
