The Supplementary Services for Previously Non-Public-School Institutionalized Students in New York City was designed to assist students who were formerly educated at state-operated or state-supported schools to adapt to public school education. The 1982-83 program served 1054 students in 367 sites, which included community schools, high schools, a special school for the deaf, special education schools, and approved work sites. Approximately 50 percent of the students were mentally retarded, 20 percent were emotionally handicapped, and the remainder had other disabilities. The age range was from 6 to 2l. Analyses of data gathered to evaluate the program indicated that most of its objectives were largely or completely met. Students demonstrated positive growth in communication, reading, math, sensory and motor development, self-help and societal/community living skills, social interactions, and vocational competencies. Observations and interviews indicated that, for the most part, program services met the individual needs of the students and effectively supplemented basic instructional activities. However, all aspects of the program suffered from delays in funding approval. In addition, although program-eligible students were identified before the beginning of the program cycle, locating many of them in particular classes at particular sites was difficult. (CMG)
