The Diagnostic Achievement Battery-Third Edition (DAB-3) is a revision of one of the most popular and useful individual tests of school achievement ever made. The DAB-3 uses 14 short subtests to identify a child's strengths and weaknesses across several areas of achievement.
The DAB-3 generates standard scores (M = 10, SD = 3 for the subtests, and M = 100, SD = 15 for the composites), percentile ranks, and age/grade equivalents.
The DAB-3 includes a supplemental manual enabling the examiner to probe student responses on the standardized test. The purpose of probing is to identify the thinking processes and problem-solving strategies that result in both correct and incorrect responses.
