Charter School Performance Study Finds Small Gains

Charter students on the whole end the school year with reading skills eight instructional days ahead of public school kids, and perform at about the same rate as public school students in math, according to the study released Tuesday by Stanford University’s Center for Research on Education Outcomes, or CREDO.

In math, the study found that 29 percent of charter schools showed “significantly stronger learning gains” than their public school peers, with 40 percent performing similarly and 31 percent “significantly weaker.” In reading, 25 percent of charters showed “significantly stronger learning gains” than public schools, 56 percent showed no difference and 19 percent showed “significantly weaker gains.”
