A Comparison of the Wrat and the Piat With Learning Disability Children

Abstract

This study was concerned with the comparative performance of learning disability children on the WRAT and the PIAT. Correlations between corresponding subtests of the two instruments were quite high for Reading and moderately high for Spelling and Arithmetic across four age levels (7 to 8, 9, 10, and 11 year olds). It was concluded that the utility of the PIAT is as promising as that of the WRAT, although diagnosticians using the PIAT may wish to exclude the Reading Comprehension subtest, as this subtest tends to be measuring the same skills as Reading Recognition at the lower grade levels.
