As a normative study of the Raven Colored Progressive Matrices (CPM), the booklet form of the CPM was administered to 357 healthy individuals (181 males and 176 females) who were selected by stratified sampling procedure reflecting the recent Korean census data in terms of major demographic variables, such as sex, age, education. Although there was no difference of the CPM scores between men and women and between urban and rural, it was found that age and education influence the CPM scores. Therefore, normative data were provided for age and education group separately. The internal consistency (Cronbach's alpha) of the CPM was .90. The construct validity of the CPM was investigated by factor-analyzing the 36 items, yielding 3 factors that were congruent with the original 3 subsets. A significant correaltion (r=.65, p<.001) was found between the CPM and the Vocabulary score of the KWIS, indicating that the CPM is a valid measure of intelligence.
