This article provides norms for Raven's Progressive Matrices, based on the screening of 500 vocational counseling and 2992 psychiatric veteran patients newly admitted to a Virginia-based general medical and surgical hospital. From 1973 to 1978 the untimed use of the Raven Matrices was continued routinely in the counseling center at the hospital and it was also used in the routine post-admission test screening of black and white veteran patients from the psychiatric service of the hospital. It appears that Raven scores obtained in non-individual group-testing with hospitalized psychiatric patients, in addition to providing the practical advantages of this kind of testing, approach the reliabilities reported for full scale WAIS-R intelligence quotient scores when the test is administered individually in a normal population for these age ranges, example, 96-98.
