The present study investigated the stability and concurrent validity of the Peabody Individual Achievement Test. The sample of 36 children were of below average intelligence and were either referred for or placed in special educational programs. Good reliability coefficients were noted over a 12-mo. period (Median R = .61; Total Test R = .58) as well as significant correlations with the WISC-R Verbal and Full Scale IQs. Implications of these findings are discussed.
