Normative Data

Normative Data

Test reliability was studied in various ways: coefficient alphas, alternate form (immediate administration), test-retest, alternate form (delayed administration), and interscorer. All coefficients are over .90, which indicates the test's high reliability. Additional studies confirmed the TWS-5’s content-description, criterion-prediction, and construct-identification validity. Especially encouraging are the new studies of the test’s sensitivity, specificity, and ROC/AUC.

The TWS-5 was normed on a representative sample of 1,634 students from 23 U.S. states. The analyses show no gender or racial bias in the TWS-5 items.
