This report presents a replicable model for developing a magnet school based on the planning of the Dallas Independent School District's Science and Technology Magnet High School. The model is based on Malcolm Provus' process called "Discrepancy Evaluation," designed as a guide for public school programs to describe the discrepancy between expectation and performance. The model contains four levels with each level more detailed than the previous one. At each level there are four components: the network, the input-process-output, the activity schedule, and the flow chart. The remainder of the report presents a description of the history of magnet schools, visitation reports, the educational specifications, consultant reports, and an annotated bibliography. (SA)
