The WISC-R Performance Scale was administered to 59 prelingually deaf children. The internal consistency reliability to four of subtests and the Performance IQ were assessed anf found to be similar to the reliability reported by Wechsler (1974) with the standardization sample. Two aspects of criterion-related validity were computed. Concurrent validity as demonstrated by the correlation with the Hiskey-Nebraska Test of Learning Aptitude was found to be adequate. Predictive validity as defined by the correlation with achievement test results was also computed. Statistically significant correlations were found for six of the eight achievement areas. Implications for use are discussed.
