We commonly use KEDI-WISC IQ test for the purpose of screening of children who are delayed, developed. But it takes more than an hour to have a test, has difficulty in interpreatation. Colored Progressive Matrices(CPM), introduced in 1938, evaluates children's intelligence by measuring the ability to from comparisions, to reason organized spatial perceptions into systemically related whole, It is used in the test of the children from 5 to 11 years of age. It takes about 2 minutes to administer and is east to interprete. This study examined the correlation between CPM IQ and KEDI_WISC IQ to determine the usefulness of CPM IQ test. Eighty-two children, aged 5 to 11 were tested on the basis of age, sex and KEDI_WISC score. The results were as follows;

1) There were significant correlations between CPM IQ and KEDI-WISC IQ, verbal IQ, performance IQ regardless of sex and age.

2) There were significant correlations between CPM IQ and KEDI_WISC IQ regardless of KEDI_WISC score although relatively low correlations exist between CPM IQ performance IQ in high KEDI_WISC score group(above 85), and CPM IQ and verbal IQ in low KEDI_WISC socre group(below 84).

Above result showed that CPM IQ is useful screening test for selection of delayed developed children.
