Measuring School Effectiveness in Memphis--Year 2. Final Report

New Leaders for New Schools, a nonprofit organization committed to training school principals, heads the Effective Practices Incentive Community (EPIC), an initiative that offers financial awards to effective educators. New Leaders and its partner organizations have received from the U.S. Department of Education tens of millions of dollars in financial support for EPIC. Through this initiative, New Leaders offers financial awards to educators in two urban school districts and a consortium of charter schools. New Leaders contracted with Mathematica Policy Research to help design the methods for identifying effective schools and teachers. This report presents the method used to identify effective schools in the Memphis City Schools (MCS), one of the partner school districts, during the second year of this project. This year's model differs from last year's model in that the authors used a shrinkage estimator to help ensure that schools with small numbers of students in their model were not overrepresented at the top and bottom of the resulting performance measures. A shrinkage estimator is a statistical technique that "shrinks" the school effects toward the average, with greater shrinkage for schools whose results were less precisely estimated--typically smaller schools. Key aspects of the Mathematica model are outlined in this paper, along with a more detailed technical description, found in the appendix. (Contains 1 table, 3 figures and 12 footnotes.)
