In order to develop a formula to measure effective schooling and student achievement, a number of reports on excellence in education were reviewed: (1) The National Commission on Excellence in Education's report, "A Nation at Risk"; (2) The Education Commission of the States Task Force on Education for Economic Growth report; (3) The Twentieth Century Fund Task Force on Elementary and Secondary Education Policy report; (4) John Goodlad's study, sponsored by the Martha Holden Jennings and Kettering Foundations; and (5) Theodore Sizer's research, sponsored by the National Association of Secondary School Principals. It was commonly concluded that all students should be expected to achieve at their optimum level; that boards of education and school principals must take responsibility for school effectiveness and environment; and that student outcomes must be emphasized. Research identified five correlates of effective schools: institutional focus; school climate; instructional leadership; teacher expectations; and monitoring pupil progress. These factors were included in an achievement grid which was developed for field testing in public schools in Ohio. Other components included prior achievement, aptitude, anticipated and actual mastery, attendance, and student attitudes. A plan for conducting the field test was presented. A seven-page reference list concludes the report. (GDC)
