Standard and modified administrations of the Iowa Tests of Basic Skills with learning disabled students.

The purpose of this study was to investigate the performance of junior high school learning disabled students on standard and modified administrations of selected subtests from the Iowa Tests of Basic Skills. No significant differences were noted for correlations between types of administration and teachers' ratings on any of the subtest comparisons. Grade placements for Vocabulary and Reading Comprehension using the modified administration were significantly higher than those using the standard administration and more closely aligned with teachers' ratings. Math Concept and Math Problem-solving grade-placement scores did not differ by type of administration; teachers' ratings were higher than those produced by either testing format.

Comparison of arithmetic measures with learning disabled students.

Four measures of arithmetic skills were evaluated for 69 learning disabled students (58 boys, 11 girls; 6 to 14 yr. old). These measures were the arithmetic subtests of the Wide Range Achievement Test and Peabody Individual Achievement test, the Key Math, and teachers' ratings. Partial correlations were high, indicating substantial content validity. Mean grade placement scores were generally equivalent for Key Math and teachers' ratings. The Peabody Individual Achievement Test produced significantly higher while the Wide Range Achievement Test resulted in significantly lower grade-placement scores than the other two measures.
