Title:  WWC Review of the CREDO Charter School Studies
Description: The study, National Charter School Study: 2013, examined the effect of charter schools on annual student achievement growth in reading and math in 25 states, the District of Columbia, and New York City. The study primarily used data on students in grades 3-8, but additional elementary and high school grades were included for several states. Researchers compared year-to-year test score changes from state-level standardized reading and math tests administered during the 200809 through 201011 school years. This research meets WWC evidence standards with reservations. Although the charter school students and traditional students were well matched, using demographic and academic characteristics, unobserved differences may have existed. In addition, the study results are difficult to interpret because they blend 1-year gains from the first year of charter school attendance and 1-year gains during subsequent years.
