The Public Law 89-313 Instructional Support Program is a federally funded program that serves handicapped students who were enrolled in state-operated or state-supported settings for a minimum of 1 year and then transferred to a New York City public high school. The 1986-87 program emphasized teacher training, consisting primarily of in-class support, consultation, and workshops. Students received special education services based on Individual Education Plans (IEP) that took into consideration their skills and abilities. The program's stated evaluation objective was that 75 percent of students whose teachers were assisted by the program would achieve their IEP objectives in the subjects in which their teachers received instructional support. During the 1986-87 school year, in which 201 students enrolled in 75 high schools received services from participating teachers, 81 percent of the students met all of their IEP objectives. Interviews with a sample of supported teachers and assistant principals indicated that the assistance which teacher trainers provided was viewed positively. This evaluation report focuses on program structure and implementation, analysis of outcome data, and recommendations. (JDD)
