This resource guide is designed to summarize the relevant research and practical information currently available to administrators on school effectiveness. The guide consists of two major sections to aid in the development of planning skills and the implementation of programs to increase student and teacher performance. The first section details the "Process Steps": formation of teams, assessing needs, establishing priorities, developing action plans, implementation of the plans, monitoring progress, and evaluation of the impacts. The second broad area covered is labeled "School Effectiveness Variables" and reviews the research on school goals, instructional leadership, setting high expectations, time on task, student performance, safe environment, and home-school relations. In each subtopic actions are suggested, the research is summarized, considerations for the principal are given, and selected references are included. (LMS)
