A systems approach to evaluation of the Diagnostic Reading Clinic Program's progress and its effects upon participating pupils from the Cleveland schools is reported on in this document. Formal evaluation of the Diagnostic Reading Clinic Program is directed toward the following objectives: to assess the extent to which the Diagnostic Reading Clinic has fulfilled its objectives; to describe, through objective measurement and statistical analysis, the amount of reading growth pupils have achieved through the diagnostic-prescriptive approach proposed by the clinic; to inform the clinic staff, administration, school personnel, and other concerned audiences of the current status of the Diagnostic Reading Clinic's efforts with pupils; and to provide feedback to those who are directly concerned with the direction, management, planning, implementation, and instructional operations of the clinic concerning implications which have resulted from the analysis of data collected for purposes of evaluation.
