A TEST BY the British psychologist, J. C. Raven, the Progres sive Matrices* would appear to have a variety of important uses in American Schools. The first possible use to be investigated in the East Chicago Schools was that of testing non-English-speaking children to help in de termining where to place them. Each September between 2 5 and 5 0 Puerto Ricans, Mexicans, and European DP'S present themselves for admission to the East Chicago schools. The policy had been to test such individuals with the Arthur Performance Scale, which procedure is sat isfactory as long as only a few individuals are to be tested. In Septem b e r, 1950, 33 children were tested with both the Raven and the Arthur tests. The correlation between the Arthur mental-age scores and the corres ponding Ravens raw scores was +. 80. Since the Ravens test isprac tically self-administering and can be administered to groups by teachers without special training, it has been used since 1950 instead of the Arthur to place non-English-speaking children. The advantages of the Raven test for use with recent immigrants sug gested its substitution for the Pintner Non-Language Mental Test to measure the intelligence of children as they entered the fourth grade ; accordingly an investigation was made during the school year of 19 51 1952 of this possible use. Mr. Raven states in the Guide that Progressive Matrices cannot be given satisfactorily with a time-limit and takes up to 45 minures to com plete. In a preliminary investigation in which no time limit was used, the majority of subjects finished within thirty minutes; a few took over an hour. It seemed desirable to complete administering the test in one period if possible. Thirty minutes net was accordingly used in the fall semester and thirty-five in the spring. Large-scale reproductions of Items A 1 and A 2 were prepared for demonstrating the answering of the test so as to lessen the dependence on verbal instructions. Because of the changes in administering the Raven Test it se e m e d desirable to check rather completely the properties of the test under the new conditions. It was accordingly administered to 944 pupils in the fall semester of 1951 and to 216 the following spring, distributedas follows :
