The report covers the replication and continuation efforts of Project UPSTART, a program in Washington, D.C. and southern Maryland, for severely retarded and multihandicapped infants and young children. The sequenced neurosensorimotor program (SNSP) provides the following services: a diagnostic educational prescriptive program; therapeutic activities; psychological services; social work services; professional and paraprofessional training; volunteer training; and orthopedic, neurological, and pediatric clinics. The project identified replication sites and provided assistance in the areas of staff training, followup consultation, child/parent programing, and evaluation. The SNSP was field tested with a total of 79 children and their families at the replication sites, the two model classrooms, and a public school classroom. A total of 166 university students, teachers, therapists, paraprofessionals, and volunteers were trained in the program. Most of the report consists of statistical data, reprints about the program, schedules, letters, and other program materials. (DB)
