- Test Field. The test field code and name.
- Form (A, B, C, etc.). For each test field, a letter code designates the different test forms—each comprising a different set of scorable multiple-choice items—that were administered during the reporting period. Test forms are considered to be identical if they contain identical sets of scorable multiple-choice items, regardless of the order of the items.
- Number of Tests Taken. The number of tests taken during the reporting period, including those tests retaken by the same examinee.
- Total Test Scaled Score Indices
- Mean. The mean of the total test scaled scores achieved by the examinees taking the test form, reported for each test form taken by 10 or more examinees.
- SEM. The standard error of measurement of the total test scaled scores (Brennan 2001), reported for each test form with at least 60 attempts.
- Decision Consistency. The total test decision consistency index of the total test scaled score (Breyer and Lewis 1994), reported for each test form with at least 60 attempts.
- Stratified Alpha. Stratified coefficient alpha, reported for each test form with at least 60 attempts.
Multiple-Choice Section
- Length. The number of scorable items in the multiple-choice section.
- KR20. The Kuder-Richardson index of item homogeneity.
G Coefficient. The Generalizability coefficient reported for each test form with at least 60 attempts.
