Measuring Charter Performance: A Review of Public Charter School Achievement Studies
Friday, December 3, 2010
Do you know how many studies on the academic achievement of charter schools have been conducted since the opening of the first charter school in the United States in 1992?
According to the Sixth Edition of the National Alliance of Public Charter Schools report, "Measuring Charter Performance: A Review of Public Charter School Achievement Studies," the answer is 284, of which 203 are included in the review because they meet the criteria established for inclusion in the report.
The eligibility criteria for inclusion in the review include that: the studies compare charter school achievement with that of traditional public schools, they use serious research methodologies, and they examine a significant segment of the charter school sector.
The studies are divided into three categories: panel studies that use longitudinally-linked student level data; cohort change studies that look at performance changes over time, using methods other than following individual students; and snapshot studies that look at student performance at one point in time. (You may remember that the 2008 Office of Legislative Auditor Report on charter schools used a snapshot approach when it looked at the academic performance of charters in Minnesota.)
