As part of comprehensive psychoeducational assessment procedures, the Quick Test of Intelligence, Test of Nonverbal Intelligence, and the Wechsler Intelligence Scale for Children‐Revised were administered to 89 children and youth, who varied in age from 6‐4 to 16‐10. The sample consisted of 61 males and 28 females, of whom 37 were Black and 52 White. Regression equations were computed that used the WISC‐R Full Scale IQ as criteria and the TONI and QT as predictors. The results clearly indicated that the TONI and QT are equally good predictors of the WISC‐R FSIQ. Implications for the clinician are discussed.
