This publication describes the Program Evaluation and Review Technique (PERT) network for the Preparing Regular Educators for Mainstreaming (PREM) project. PREM is a competency-guided program being developed at the University of Texas at Austin to prepare educators to meet the needs of exceptional children in the regular classroom. PERT is an administrative device for the improvement of the planning, controlling, and decision-making activities experienced in project development. This publication presents the PERT network developed for use in the three-year PREM project. Estimated expenditures of time for various activities and planned completion dates for different events are outlined. In an attempt to channel resources for the most effective utilization of time and energy, the critical path for the completion of the activities is provided. Also included are flow charts illustrating both intracluster and intercluster functioning. (Author/JG)
