The WISC‐R and WAIS were administered to 30 16‐year‐old EMH students in a test‐retest design to distribute practice effects. The average interval between administrations was approximately 37 days. Results from t ‐tests of significance of difference between the means were obtained for the total group and for two subgroups, one receiving the WISC‐R first and one the WAIS first. Analysis of data revealed significantly higher WAIS scores on all levels of VIQ, PIQ, and FIQ for all groups.
