The Wide Range Achievement Test and the Peabody Individual Achievement Test: A Comparative Study.
Harmer, William R.; Williams, Fern
A comparison of the Wide Range Achievement Test (WRAT) and the Peabody Individual Achievement Test (PIAT) indicates that the two should be used interchangeably only with caution and understanding of the differences. While there is a moderate to high correlation between the test scores, nevertheless, the two have distinctly different strengths and weaknesses. The WRAT tends to be more accurate for older subjects (grades four through twelve) while the PIAT tends to be more accurate for younger subjects (kindergarten and primary grades). The differences in test content, testing procedures, test format, and method of scoring may account for the differences in grade equivalent scores on the two, especially on the math subtests. (TJ)
