UNDATED (AP) -- A study on charter schools finds they tend to benefit students from poor families, black students and Hispanic English-language learners more than peers in other groups.
The study from the Center for Research on Education Outcomes at Stanford University in California shows overall charter school students are faring better than they were four years ago, surpassing those in traditional public schools in reading gains and keeping pace in math.
The study updates and expands upon 2009 findings comparing student performance on standardized reading and math tests.
American Federation of Teachers president Randi Weingarten says the findings show charter schools have failed to live up to promised performance gains.
The study analyzed student data from 25 states, the District of Columbia and New York City.
