During the last five years, the Instructional Support System for Occupational Education (ISSOE) in New York State has grown to involve approximately 3,000 teachers in development activities. To manage this system, a management information system was set up to develop reports on student progress, student decision making, and planning for student programs. Guides for teachers and administrators were prepared for each of these areas, as well as a guide providing an overall view of the system. A field test was conducted for six months in order to see how well the various components of the system were functioning. The majority of the field test was evaluated by descriptive comments and talks with teachers and administrators in the field. In addition, student questionnaires were administered. In general, results of the field test showed that the system was working well, and all who were involved with it felt that it was a positive effort. Five recommendations, mostly having to do with expanding capabilities of assessment through computerization, were made. (KC)
