This study examined the deaf norms of the Hiskey-Nebraska Test of Learning Aptitude (H-NTLA) (Hiskey, 1966) by comparing the distribution of scores obtained on the H-NTLA with those from the Wechsler Performance Scales (Wechsler, 1955, 1967, 1974) for the same hearing-impaired children. A correlation of .85 was found between the H-NTLA and the Wechsler Performance Scales; however, the H-NTLA yielded a greater number of subjects with extreme scores (i.e., scores <70 and > 119) than the Wechsler scales. These findings indicate the need for caution and convergent evidence in the interpretation of extreme H-NTLA scores in hearing-impaired children.
