This report presents 1979-80 evaluation findings of the Non-Public Schools Learning Resource Center, in Detroit, Michigan. The center, funded by Title I, provided diagnostic/prescriptive-learning techniques to 1,400 students (in 27 non-public schools) who had learning difficulties in mathematics and reading. The first section of the report discusses: the project's rationale; its functions and responsibilities; eligibility criteria, the referral process; diagnostic and prescriptive procedures; parental involvement; and the process of student monitoring and documentation by staff members. The second section explains methods utilized to evaluate students (based on results of pre- and post-California Achievement Tests and the Stanford Diagnostic Test). The third section indicates how data was analyzed and evaluated after students were screened and diagnosed. Finally, section IV presents statistical tables that indicate student achievement by project objective. The project is said to have been effective in implementing the proposed activities and continuation is recommended. Appended to the report are samples of questionnaires administered to staff, teachers, and parents regarding their perceptions of the learning center, as well as a copy of the inservice training evaluation instrument.
