Presented are evaluation reports on four special education programs in the District of Columbia Public Schools: a daily program for the development of linguistic and conceptual ability in 12 aphasic children, emphasizing language reception and expression; a complete instructional program for some 18 multiply handicapped, hearing impaired rubella children ages 4-9 years; a program based on principles of behavior modification and called DILE (Designed Individualized Learning Environment) for 35 seriously emotionally disturbed or socially maladjusted children; and a program focusing on the training of adaptive behaviors in 38 severely mentally retarded children. Evaluation techniques included observation of behavioral changes, performance measures, analysis of diagnostic tests, anecdotal and cumulative records, and interviews or reports from social workers, psychiatrists, parents, teachers, principals, and project directors. A summary and a consultant's detailed systematic evaluation are given for each project. Consultants' examine extent to which projects meet objectives, strengths and weaknesses, and successes and failures of projects. Recommendations and some statistical data are included. (KW)
