Abstract
A national survey of 856 school psychologists was conducted to assess practitioners' perceptions of the intellectual domains assessed by, and the ease of administration, interpretation, and usefulness of, four commonly used measures of intelligence: the Kaufman Assessment Battery for Children; the McCarthy Scales of Children's Abilities; the Stanford-Binet, Form IV; and the Wechsler Intelligence Scale for Children-Revised. A 31% return rate was attained, which resulted in 267 completed surveys returned. Results indicated that the Wechsler Intelligence Scale for Children-Revised was by far the most popular instrument and was perceived as the most valid measure of intelligence, the overall “best test,” and as the test that provides the most useful diagnostic information.
