title: Criterion-related validity of a new classification scheme for institutionalized mentally retarded individuals.
abstract: Two studies were carried out to test the validity of a new three-cluster classification scheme. The association of cluster membership with both clients' movement and program placement was significant, but only in the case of the latter criterion was prediction improved by knowledge of a client's cluster membership.
