The report describes the third and final year of a 3-year case study of the technical assistance process as implemented by the Technical Assistance Development System (TADS) for the staffs of two demonstration programs for preschool handicapped children and their families. Following a review of TADS and the two demonstration programs, the development of the conceptual framework for the study is recounted. The bulk of the report is devoted to case reports of the technical assistance delivery process as it occurred during fiscal year 1981-82. A story-telling approach is used to present the observations regarding settings, individuals, events, and interactions. Processes described include initial needs assessments, phone conferences, followups, on-site and off-site consultations, and final interviews. (CL)
