This paper describes an evaluation study of the use of paraprofessional personnel in school districts in general, and at Parma (Ohio) Schaaf Junior High School in particular. The members of the evaluation team included representative teachers from the school system led by a university coordinator. They describe problems and promising practices in regard to how paraprofessionals are used in the classroom. This information was gathered from documents and references available through the ERIC retrieval system. In addition, the evaluators discuss what Parma educators believe are the advantages and disadvantages of the extensive use of university students as instructional aides. The major purpose of the paper is to relate the findings of an evaluation study implemented at the high school during spring 1976. The study focused on how university students were trained to be competent instructional aides. The study, based on the Stufflebeam and Guba "CIPP" model of evaluation, concludes with a series of recommendations to improve the training system that assists paraprofessionals and the faculty persons who supervise them.
