This paper presents guidelines for developing programs for the early detection of physical, behavioral, and educational problems of young children. The purpose, definitions of terms and roles, procedures for organization and implementation of the screening programs are briefly outlined. The paper consists primarily of supporting information: (1) post-screening activities and resources, including procedures for follow-through, national, state and local resource directories of services for children, and follow-up activities designed for gross and fine motor development, speech and language stimulation, and personal and social development; (2) a survey of available screening instruments and procedures which provides information helpful in determining which instruments would be most appropriate for the local situation; (3) procedural guidelines for vision and hearing screening; and (4) brief descriptions of four model training programs currently in operation in Missouri.
