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.
- We accept data in any format. Electronic data or "bubble sheets" are both acceptable. There is no limit on what type of bubble sheet that can be sent; even homemade sheets will be capable of providing the data needed.
- We attempt to maintain some small measure of demographic data – particularly gender of students. If possible, we appreciate having gender data included for each student performance.
- Information from the Examiner's Report Form is also helpful and requested.
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:
