Stability of WISC-R subtest profiles for learning disabled children

Stability of the WISC-R subtest profile for 161 learning disabled (LD) children over a 7-month test-retest interval was examined. A unique subtest profile reported earlier (Smith, Coleman, Dokecki, & Davis, 1977a) was replicated. Performance IQ was significantly greater than Verbal IQ at both testing occasions. A mean test-retest increase was observed for Performance IQ, but not for Verbal IQ.
