Presented are evaluations of eight 1973-75 objectives of the Oregon Model Center for children with learning disabilities. The center was developed to facilitate expansion of the Educational Evaluation Center, a diagnostic-prescriptive center at Oregon College of Education. Among objectives evaluated are: studying the process of the Education Evaluation Center to develop more efficient and effective methods of diagnosing and prescribing for learning disabled children; developing minidemonstrations of methods and materials to be delivered with the prescription for the child; and developing a training program for administrators of Diagnostic-Prescriptive centers. Included is information such as suggestions from advisory councils regarding changes in the diagnostic-prescriptive process; results of followup studies in which teachers and parents were surveyed; descriptions of materials produced for parents and teachers; contents of a diagnostic-prescriptive manual; and evaluations of the three pilot centers established. Appendixes include parent and teacher followup forms and the diagnostic-prescriptive service program report from a local school district. (LS)
