| Abstract: | This study investigated whether the Minnesota Percepto-Diagnostic Test-Revised (MPD-R) or the Bender-Gestalt (BG) would most accurately predict achievement at the first-, third-, and fifth-grade levels. Both tests were administered to 84 children (28 at each grade level) in a counterbalanced order. Data were analyzed using Pearson product-moment correlations, t tests for significance of difference between dependent correlations, and partial correlations. Results indicated that the MPD-R is a better predictor of achievement than the BG, especially at the first-and fifth-grade levels. At each grade level, the MPD-R scores correlated more highly with more achievement than did the BG. |
