The sixth annual comprehensive evaluation report of the U.S. Office of Education (OE) reviews approximately 90 programs administered by OE as of September 30, 1976. It updates the information in the fiscal year 1975 report by incorporating the results of evaluation studies completed during FY 1976 as well as additional information obtained from program operations and monitoring activities. Elementary and secondary education, post secondary education, handicapped and special education, vocational and adult education, and developmental programs are described. Each program report outlines funding history, program goals and objectives, program operations, program scope, program effectiveness and current progress, and ongoing as well as planned evaluation studies. A discussion of the impact of evaluation findings on federal decision making, a progress report on the implementation of Title I evaluation requirements, a summary of current planning and evaluation contracts, and a report on the status of reports mandated by Congress are also included.
