Issue: The Knowledge is Power Program (KIPP) is a network of charter schools designed to transform and improve the educational opportunities available to low-income families, and ultimately, prepare students to enroll and succeed in college. KIPP has grown from a core of two middle schools established in the mid 1990s to a nationwide network of 82 schools in 19 states and the District of Columbia. In the wake of its growth, the KIPP Foundation was eager to rigorously assess the programs’ effectiveness and identify best practices that lead to positive student outcomes.
Study: Mathematica Policy Research is conducting a multiyear evaluation of KIPP scheduled to continue through 2014. The evaluation includes both experimental and quasi-experimental components designed to examine KIPP’s impacts on student achievement and college readiness. This initial report uses a matched, comparison group design to estimate KIPP’s effects on achievement in 22 middle schools—making this the first study that applies a rigorous (nonexperimental) methodological approach across a nationwide sample of KIPP schools.
Findings: For the vast majority of KIPP schools included in the initial report, impacts on students’ state assessment scores in mathematics and reading are positive, statistically significant, and educationally substantial. The main findings include:
Quote: “The positive impacts in KIPP schools are compelling in their consistency and size across diverse states and students served,” said Christina Clark Tuttle, researcher at Mathematica and co-author of the report. “In future reports, we’ll incorporate even more KIPP schools and students, examine effects on other student outcomes beyond state test scores, and test the robustness of the results against different analytic methods.”
The Report: “Student Characteristics and Achievement in 22 KIPP Middle Schools.” Christina Clark Tuttle, Bing-ru Teh, Ira Nichols-Barrer, Brian P. Gill, and Philip Gleason.
