Total scores of the Raven's Standard Progressive Matrices (SPM) were correlated with Wechsler Adult Intelligence Scale‐Revised Full Scale IQs (WAIS‐R FSIQ) in order to obtain age‐stratified estimates of WAIS‐R FSIQ ( N = 308). Results show a significant positive correlation between age‐stratified WAIS‐R FSIQ and SPM in all age groups except those 65 and older and between educational level and SPM for all age groups except the very young (16 to 24 years), the 55‐ to 64‐year‐olds, and the elderly (65 and older). A multiple regression and cross‐validation revealed that race and age also must be used as moderator variables when one is predicting FSIQ in this population. It is concluded that the SPM can be used as an estimate of WAIS‐R FSIQ.
