Comparison of the Slosson Intelligence Test and the Stanford-Binet Intelligence Scale,Fourth Edition,with Children Referred for Psychoeducational Assessment

Abstract

The Slosson Intelligence Test (SIT) and the Stanford-Binet, Fourth Edition (SBIV) were administered to two groups of children referred for psychoeducational evaluation. Group 1 participants were referred because of concern for learning progress, and Group 2 participants were referred as potentially gifted. Taken at face value, SIT scores significantly overestimated all SBIV scores for potentially gifted students and significantly underestimated four of five SBIV scores for students with learning problems. However, in 9 of 10 instances across groups, the SIT correlated significantly with SBIV area and composite scores. In both groups the SIT predicted the SBIV verbal reasoning score more accurately than the composite score. Overall, the SIT predicted SBIV performance better for students with learning problems. Use of the SIT to screen students for subsequent SBIV evaluations is discussed.
