An equally weighted WPPSI short‐form (Comprehension, Arithmetic, Block Design, and Picture Completion) was administered to 64 prekindergarten children, while a verbally weighted WPPSI short‐form (Comprehension, Arithmetic, Block Design, and Vocabulary) was administered to 63 prekindergarten children. All subjects subsequently were administered school achievement tests at the end of the first‐ and second‐grade years. Low, but significant correlations between the FSIQ and achievement test scores were obtained; the Arithmetic and Block Design subtests were the best subtest predictors of school achievement in grades one and two. The predictive validities of the two WPPSI short‐forms were found to be essentially equivalent.
