The purpose of this study was to compare and contrast the diagnostic value of the Wechsler Intelligence Scale for Children (WISC) and the Wechsler Intelligence Scale for Chil- dren-Revised (WISC-R) in the development of the individualized educational program (IEP). An essential component of the study was to determine if the student identified as learning disabled with the WISC would have a significantly higher score on the WISC-R.

The age range of the subjects for the WISC-R administration was 9 years, 10 months to 14 years, 0 months.

The tests were administered by 12 educational diagnosticians and completed within a 46 day period. The principal investigator had no contact with the students or the diagnosticians. [...]
