Results of an evaluation of the 1981-82 Public Law 89-313 program, "Supplementary Services for Previously Non-Public-School Institutionalized Students," are presented in this report. The program was operated by the Division of Special Education of the New York City public schools and served 527 students (6-21 years old) in 227 schools, including community schools, high schools, a school for the deaf, special education schools, and an approved work site. The report's introduction describes how the program helped students who were formerly educated in State-operated or State-supported schools to adapt to public school special education. Approximately 50 percent of these students were emotionally disturbed and 30 percent were mentally retarded. Chapter 2 documents the overall level of program implementation by focusing on facilities, staff, and levels of services provided. Chapter 3 presents evaluation findings for the program's four subcomponents: regionalized services, citywide services, hearing handicapped services, and placement and referral services for the handicapped. These findings focus on activities, resource materials, budget problems, promising techniques, and attainment of objectives, and are based on analyses of pupil achievement data. As is indicated in the report's final chapter, the program is judged to have met or exceeded its objectives, but a number of suggestions are offered for improving resource allocation, use of supplies, staff utilization, and record keeping.
