Thirty-five gifted elementary children were tested with the Wechsler Intelligence Scale for Children III (WISC-III) and results were compared to a previous administration of the WISC (Revised). Scores were significantly higher on all three WISC-R global scales and most subtest scaled scores. Correlation coefficients between the tests were…

Comparison of Wechsler Intelligence Scale for Children (WISC)-Revised and WISC III IQs for 64 students with specific learning disabilities and 55 students with mental retardation (MR) found that correlations were lower than those reported in the WISC-III manual. Only Performance IQs for students with MR matched the correlations reported in the…

Compared the derived mental age (MA) of the Stanford-Binet to the test age (TA) of the Wechsler Intelligence Scale for Children (Revised) in 100 children. For subjects whose WISC-R scores fell within the TA table, the two were comparable. When extrapolated TAs were required, the scores were not comparable. (Author/JAC)

Though some unexpected sex differences were discovered, the two diagnostic categories were not found to be psychometrically distinct. Further, the results of a longitudinal analysis suggested that, while IQ scores remained relatively stable over time within a subset of the original sample, achievement scores definitely declined.

Slosson Intelligence Test scores are the best predictor of Wechsler Intelligence Scale for Children (Revised) (WISC-R) IQ scores. But they are often higher than WISC-R scores and increasingly verbally weighted. A skilled teacher's classroom observation is as valid an indicator of need for in-depth assessment as screening tests.

Cognitive differences between 987 LD children and 178 EH children in public schools on a psychoeducational assessment battery were studied, and differences in factor structure were investigated. Caution is suggested in interpreting the results of multivariate statistical analyses, which indicated heterogeneity in the matrices of LD and EH…
