The final report describes the evolution and accomplishments of a project designed to identify factors associated with successful completion of education/training programs for mainstreamed mildly handicapped secondary students. Program outcomes were measured via examination of the student records, interviews, and recollections of special education practitioners. In chapter 1, an overview of the project is presented. A summary of findings revealed that students with less serious handicaps were more likely to complete secondary training than were those with more serious handicaps; the secondary special education program appeared effective in helping the majority of students to function in the regular high school environment, and the effects of program intervention did not seem to be uniform across categories of handicap or for students from different backgrounds. Findings supported the need for data-based decisionmaking. A second chapter describes in detail the research methodology and the final dispositon of the students. Chapter 3 examines three aspect of secondary program operation: level of intervention of program staff in students' academic programs, extent to which a student's history in special education influences the current level of functioning, and the effects of a district's discipline policies on the academic programs of handicapped children. The final chapter offers a causal model of special education services designed to evaluate program operations by examining the interrelationships of program variables. (CL)
