The relationship of the WISC-R Arithmetic and WRAT Arithmetic scales to grades was determined for a sample of 8 female and 14 male juvenile delinquents. The WISC-R correlated .538 with grades and .302 with the WRAT, while the WRAT correlated .289 with grades. The WISC-R also correlated .508 with sex (females scoring higher). While WRAT Arithmetic is questioned as an indicator of academic achievement, WISC-R accounts for 29% of grades variance and may be a useful correlate.
