DAB-I
Diagnostic Achievement Battery–Intermediate

Phyllis L. Newcomer

    Normative Data

    The DAB-I normative sample was 766 representative students from 18 states. It yields standard scores (M = 10, SD = 3, for the subtests, and M = 100, SD = 15 for the composites), percentile ranks, and age/grade equivalents. Strong evidence is provided for internal consistency, time, and interscorer reliability and for content-description, criterion-prediction, and construct identification validity. Especially encouraging are the new studies of the test’s sensitivity, specificity, false positive ratio, and ROC/AUC and of gender and ethnic bias.
