Study of Instructional Improvement

The Study of Instructional Improvement is a research project conducted by the University of Michigan in partnership with the Consortium for Policy Research in Education.

The Study of Instructional Improvement (SII) was a large scale quasi-experiment that sought to understand the impact of three widely-disseminated comprehensive school reform (CSR) programs on instruction and student achievement in high-poverty elementary schools. Over a four-year period, researchers at the University of Michigan followed schools working with one of three CSR programs—Accelerated Schools Project, America's Choice, and Success for All. The study also followed a set of closely matched comparison schools. The purpose of the study was to track implementation of the CSR programs in elementary schools and to investigate the impact of participation in these programs on teachers, students, and schools.
