WWC Quick Review of the Report "Charter School Performance in Los Angeles Unified School District: A District and Neighborhood Matched Comparison Analysis"
What Works Clearinghouse
The study examined whether charter schools have higher growth in student achievement than traditional public schools. The study analyzed data on 79 charter schools and 593 traditional public elementary, middle, and high schools in the Los Angeles Unified School District from 2005-06 to 2006-07. School-level academic achievement was measured using the California Academic Performance Index (API), a composite measure of how well a school's students perform on standardized tests. The research described in this report is not consistent with What Works Clearinghouse (WWC) evidence standards. The study compared the annual API change in charter schools to the change in traditional schools. Although the study attempts to match charter schools to traditional public schools based on racial and income composition, parent education, and geographic proximity, it does not provide evidence that these two groups were initially equivalent on academic achievement. Although the authors use statistical techniques to adjust for some differences, it is possible that there were differences between the two groups that were not accounted for in the analysis, and these differences could have influenced changes in API. In addition, schools with very low API levels may make greater gains than other schools simply because they have more room for improvement. For these reasons, differences in API trends between the two groups of schools cannot be attributed with confidence to the effect of charter schools.
