The 1971-72 evaluation report of Project Follow Through in the Cleveland public schools focuses on the following issues: (1) degree to which product objectives at each grade level were attained, (2) degree to which such factors as project participation, teacher, preschool experience, and socio-economic factors influenced children's performance, (3) what other factors had important influences, and (4) degree to which the principles of the responsive classroom environment were evident in the classrooms. The Follow Through Project in Cleveland provides a comprehensive program of instruction and supportive services for 4 1/2 years. The instructional approach, Responsive Classroom Environment, is characterized by individualized instruction, free exploration, immediate feedback to children about the consequences of their actions, self-pacing and child orientation, and structure designed to facilitate interconnected discoveries by the learner. The project served a total of 466 children during the '71-'72 year in Cleveland. Major evaluative findings are presented, and recommendations for the program are discussed. (DP)
