Correlations of Scores of Low Vision Children on the Perkins–Binet Tests of Intelligence for the Blind, the Wisc–R and the Wrat

Abstract

The purpose of this study was to examine the correlation of the Perkins–Binet Tests of Intelligence for the Blind, Form U; the Wechsler Intelligence Scale for Children—Revised (WISC–R), Verbal Scale; and the Wide Range Achievement Test (WRAT). These three tests were administered to 52 low vision children in the third, fifth, seventh, and ninth grades in residential and day school programs in Ohio. Means and standard deviations were computed for scores at each grade level and for the total group. Results indicated that the mean ten scores on the two tests of intelligence were significantly different. In addition, there was a moderate correlation of the WISC–R with the WRAT but only a low correlation of the Perkins–Binet with the WRAT. Implications of these results are discussed and recommendations are made for further research.
