| Abstract: | WISC and WISC-R test results were correlated with achievement test scores and school grades of 36 children who had completed two years of school. Global intelligence estimates from both scales correlated at significant levels with all achievement test measures. Individual subtests from the two scales were unevenly correlated with grades in specific school subjects over both school years. Data suggest that while the two scales may be grossly equivalent as global predictors of school achievement, the individual subtests from the two scales may not correlate equivalently with specific external criteria such as school grades. |
