Wisconsin Report on Charter School Efficiency in Milwaukee Not Supported by Evidence
EAST LANSING, Mich. (Jul. 12, 2016) — A recent report from the Wisconsin Institute for Law and Liberty (WILL) attempted to estimate efficiency scores for schools in Milwaukee and make the case for greater autonomy for charter schools. The scores were used in an attempt to draw conclusions about the relative "efficiency" of Milwaukee's charter and traditional public schools. An academic review released today of the report found the strong claims about the relative efficiencies to be too weak to serve any useful function for policymakers.
The report, Bang For The Buck: Which Public Schools In Milwaukee Produce The Best Outcomes Per Dollar Spent?, was reviewed by Dr. Casey Cobb, University of Connecticut, for the Think Twice think tank review project. Cobb is Neag Endowed Professor in Educational Policy at the Neag School of Education. Think Twice, a project of the National Education Policy Center (NEPC), is funded in part by the Great Lakes Center for Education Research and Practice.
The report used a simple analysis of math and science scores divided by per pupil funding. A second analysis from the report generated "efficiency scores" by using a regression model, which accounted for selected demographic characteristics. The authors of the report claimed that schools with greater autonomy were more efficient than schools with less autonomy.
Five major problems arise from the report's approach, Cobb finds:
In his conclusion, Cobb states: "Taken on the whole, the research warrants are simply too weak to support the report's very strong claims."
