Forty trainable mentally retarded students were concurrently administered the Stanford Scale and the Wide Range Achievement Test (WRAT). WRAT reading, spelling and arithmetic subtests were regressed on Stanford intelligence quotients. Predictions were statistically valid. Derived regression equations are reported. (Author/CP)

Predictive validity of the Weschler Intelligence Scale for Children-Revised (WISC-R), was investigated with 174 Chicanos and 94 Anglos, ages 10-11, who were referred for psychological services. Wide Range Achievement Test Reading, Spelling, and Arithmetic subtest scores were each regressed on WISC-R Verbal, Performance and Full Scale Intelligence…

This study examines the usefulness of the Wechsler Intelligence Scale for Children-Revised (WISC-R) in predicting the reading achievement of 74 disabled readers in grade 3 on the word recognition subtest of the Wide Range Achievement Test (WRAT). The WRAT word recognition subtest was used because previous research has demonstrated a high positive…
