The degree of comparability between the WISC‐R and WAIS‐R over time was assessed for two samples of referred adolescents of borderline intelligence intially administered a WISC‐R and retested on the WAIS‐R after three years. Results indicated that the WAIS‐R significantly overestimated the WISC‐R IQs by 3 to 5 points. Differences were most marked at the lower ability levels; as IQs aproached average, scores were increasingly comparable.
