The report's multi-site analysis of charter schools in Chicago, Denver, Milwaukee, Philadelphia, San Diego, Florida, Ohio, and Texas concludes there is "little evidence that charter schools, on average, are producing test-score impacts" substantially different from conventional public schools. No effect size is printed in the available text.

"Overall, there is little evidence that charter schools, on average, are producing test-score impacts that are substantially better or worse than those of conventional public schools"
