Students’ gains in mathematics after three years in a charter school run by the Knowledge Is Power Program, or KIPP, are large enough in about half of schools to significantly narrow race- and income-based achievement gaps among students, according to a study of 22 KIPP middle schools nationwide.
The report, released today, is the first of a series focusing on the nationally known charter school network. Conducted by Mathematica Policy Research, Inc., of Princeton, N.J., the study was planned and commissioned by KIPP with grants from several private foundations. Plans are in the works for future reports to expand the sample to more KIPP charter schools, use randomized experimental research in a subset of schools, and look at measures other than state test scores.
