Correlations of some brief measures of intelligence with the WISC-R for a group of exceptional children.

Correlations were calculated between the Slosson Intelligence Test, Quick Test forms 1 and 3, Peabody Picture Vocabulary Test, and Wechsler Intelligence Scale for Children-R for a group of 93 students (58 boys and 35 girls) who were in Special Education classes. It was found that the Slosson, Quick Tests, and PPVT correlated higher with the verbal scale of the WISC-R than with the Full-scale or Performance scale. It was concluded that the more briefly administered tests do not provide scores that can be considered to be comparable to the WISC-R Full-scale.
