The Director of Evaluation Services of a mid-sized urban school district describes her job exchange experiences as an assistant principal in a junior high school. The background of the writer and description of the district, evaluation training in the district and returning to the field, and how evaluation fits are discussed. The purposes of the job exchange included providing on site evaluation training to building staff; providing the school administrator with evaluation supervision experience; providing the director an opportunity to view field use of evaluation methodologies and products; and the opportunity to assess problems of a particular school and developing strategies to resolve them. The administrators involved in the exchange returned to their respective positions at the end of the year. They agreed that their assignments had been a valuable personal and professional growth experience. The evaluation methodologies used at schools and those supported by central administration are related. However, there is a wide variation in perspective concerning what is of importance to school based personnel as contrasted to central administration personnel. (DWH)
