This is both a formative and summative evaluation of the 1969 Co-Operative Services for Teacher Education Projects (Co-Op STEP) as an innovative and experimental federal project. The evaluation identifies the main objectives of the project, which include experimenting with team teaching in an atmosphere of freedom and innovation, providing master teachers with leadership experience and teacher assistants with teaching experience, and developing innovative materials. The evaluation includes reports on various workshops, in-service training projects, programs, tests, and questionnaires. The Co-Op summer session is characterized as having had high interest and total involvement, but some changes are recommended. The appendixes include a map of North Carolina showing participating counties and college locations; forms used in evaluation; and possible scores by test, form, and level.
