Short form of the WPPSI and WPPSI-R.

A short form of the WPPSI, which consisted of the Block Design, Vocabulary, Arithmetic, and Comprehension subtests, was administered to 426 applicants to kindergarten at a private school. The following year a short form WPPSI-R, which consisted of the same subtests, was administered to 372 applicants to kindergarten at the same school. The FSIQs and subtest scores of the two short forms were nearly identical. The findings varied from the results of previous studies that found the complete WPPSI FSIQ to be 6 to 8 points higher than the WPPSI-R FSIQ. Limitations of the present study and of short form Wechsler IQs are discussed.
