The purpose of this practicum was to develop, implement, and evaluate a humanistic system for student registration and self-scheduling in a comprehensive high school. The author developed a model registration and scheduling system, which was introduced on an experimental basis in a Baltimore-area high school and then evaluated by staff members and students at the school. On the basis of that evaluation, the model was adopted to replace the school's former registration and scheduling system. Following several short chapters describing the objectives of the practicum and the development of the model, most of the report consists of a detailed description of the model's implementation and a discussion of its evaluation. In addition, extensive appendixes contain a flow chart and chronology of the model's development and implementation, as well as samples of all the instruments and materials used to plan, implement, evaluate, and institutionalize the model system.
