Charter School Productivity Report, Recommendations Indefensible
Nothing in the report provides any guidance for educators or policymakers
EAST LANSING, Mich. (August 19, 2014) – A recent report from the University of Arkansas Department of Education Reform (DER) on charter school productivity claims superiority of charter schools in producing achievement per dollar invested. The report, the third in a series of reports, asserts charter schools are more effective in producing achievement on standardized tests and are also less costly per pupil than traditional public schools. An academic review finds the claims made by the report rest on shaky ground and suffer from multiple sources of invalidity, rendering the report useless.
Gene V. Glass, Regents' Professor Emeritus at Arizona State University, reviewed The Productivity of Public Charter Schools for the Think Twice think tank review project of the National Education Policy Center (NEPC), with funding from the Great Lakes Center for Education Research and Practice.
The report utilizes findings from the National Assessment of Educational Progress (NAEP) and "revenues received" to support that charter schools spend less per pupil than traditional public schools and produce achievement as good or superior to that of traditional public schools.
In his review, Glass found the report inaccurately utilizes NAEP test results while discounting the fact that demographic differences between the two sectors are highly correlated with NAEP performance. In short, Glass says, "The sector with the higher percentage of poor pupils scores lower on the NAEP test."
Additionally, Glass also finds that the assessment of expenditures is based on questionable data, leaving readers with little evidence on which to base any valid conclusions.
In his conclusion, Glass says, "The report continues a program of advocacy research that will be cited by supporters of the charter school movement." Despite its many shortcomings, charter school supporters will attempt to utilize the report for an expansion of funding for charter schools.
