To examine the validity and sensitivity of the Test of Visual-motor Skills and the Developmental Test of Visual-motor Integration, 38 students with learning disabilities were administered each test twice over a 6-mo. period. Correlations between age-equivalents, percentile ranks, and zeta-scores ranged from .58 to .71, supporting the construct validity of the Test of Visual-motor Skills. However, mean scores on the Developmental Test of Visual-motor Integration were significantly higher with all three methods of reporting test results and do not support concurrent validity. Subjects made a significantly greater mean change in age-equivalent score on the Test of Visual-motor Skills, suggesting that this score is preferable for measuring change in children receiving remedial programs for visual-motor dysfunction.
