This study investigates the convergent relations of the Reynolds Intellectual Assessment Scales (RIAS) and the Wechsler Intelligence Scale for Children−Fourth Edition (WISC-IV). Data from counterbalanced administrations of each instrument to 48 elementary school students referred for psychoeducational testing were examined. Analysis of the 96 protocols reveals significant positive correlations between conceptually similar RIAS and WISC-IV sub-tests. However, overall mean scores were significantly higher for the RIAS.
