Since 1982-83, Spencerport Central School District (New York) has conducted a project to improve the educational program and student learning in each building of the district. This report provides a comprehensive overview of the project, focusing on five elementary schools. The project's goal for each building is that at least 95 percent of all students at each grade level shall demonstrate minimum academic mastery regardless of socioeconomic status. Basically, the project attempts to improve student achievement by causing the characteristics of an effective school to come into place in each building. These are: (1) safe and orderly environment; (2) clear school mission; (3) instructional leadership; (4) high expectations of students; (5) opportunity to learn and student time on task; (6) frequent monitoring of student progress; and (7) good home/school relations. The first section of the report, focusing on student achievement, offers a disaggregated analysis of each of the five participating schools. In the second section, correlates of an effective school are outlined with data on the activities pertinent to each correlate and needs assessment findings for each of the five schools. Appendices include an overview of the project and summary of responses from each school to a survey covering 1983-1990. An executive summary of the report and the application for program evaluation are included. (JD)
