There is a nationwide need for psychologists to provide services for young (birth to 6 years) handicapped children. The challenge is for psychologists to ensure adequate and appropriate assessment and intervention for children who have developmental disabilities including emotional, cognitive, sensory, and physical handicaps. This article addresses three problem areas: First, who should provide these services? second, what clinical procedures are most appropriate? and third, how can adequate training be obtained? A recently developed training program is described.There has been a dramatic increase in early childhood programs and infant stimulation services during the past decade. A major reason for the proliferation of such new programs has been public recognition of the importance of identifying, educating, and treating developmentally handicapped children as early as possible. The increased public recognition of the need for early intervention for handicapped children has resulted in changes in federal legislation, the most significant of which has been the Education for all Handicapped Children Act of 1975 (P.L. 94-142). Significantly, for younger developmentally disabled children, P.L. 94-142 requires Child Find for all children from 3 to 6 years of age (some states, e.g., California and Michigan, also require coverage of children from birth to 3 years). Child Find mandates the provision of "related services" for assessment, placement, and preparation of individualized educational or treatment plans.The law specifies that nondiscriminatory evaluations and appropriate individualized educational plans be provided for every child identified as handicapped. Under the law, developmental handicaps include emotional disturbance, mental retardation, physical disabilities, and hearing and visual impairments. As Mowder (1979) has pointed out, one critical aspect on which the success of P.L. 94-142 depends is that valid assessments be performed by appropriately trained professionals.The role of the psychologist is to ensure that appropriate assessments of handicapped children are done and that the children's treatment programs meet their needs (Schaar, 1979). The problem is that very few psychologists have the clinical skills or training to assess children under 6 years of age who have the full range of disabilities. Several surveys have suggested a nationwide need for training psychologists to fulfill the service mandates of P.L. 94-142 (Bardon & Wenger, 1976;Mowder & Demartino, 1979; Ulrey & White, Note 1).The challenge for professional psychology is how to meet the increased demand and provide appropriate services for handicapped young children. Three major issues should be considered in addressing this challenge. The first is who should be responsible within the profession? Since there currently is no clearly defined specialty group within professional psychology that addresses the needs of young children with the full range of developmental disabilities, should those responsible be school psychologists, counselin...
