In 2013, Mathematica released the second report from their multi-year study of KIPP middle schools. This report represents the most rigorous and in-depth research on KIPP to date.
KIPP middle schools have positive and statistically significant impacts on student achievement across all years and all subject areas examined. According to a matched comparison design study, KIPP students showed gains in math, reading, science, and social studies on state assessments. This finding confirms that we have been able to maintain the quality of our middle schools as we have expanded our network.
The magnitude of KIPP’s achievement impacts is substantial. Across all grade levels and subjects studied, KIPP’s achievement impacts are large enough to be educationally significant.
The matched comparison design produces estimates of KIPP’s achievement impacts similar to estimates of the same impacts based on an experimental, lottery-based design. Researchers found that KIPP’s achievement gains are similar for the matched comparison design and the experimental lottery analysis--demonstrating that parental motivation cannot explain our student’s achievement gains.
In the lottery sample, average KIPP impacts on a nationally normed test that includes items assessing higher-order thinking skills were similar to impacts on high-stakes state tests. For students in the lottery sample, gains on the national norm referenced test mimicked those on state tests.
KIPP is committed to equal treatment for all individuals. KIPP does not discriminate on the basis of race, color, gender, disability, age, religion, sexual orientation, or national or ethnic origin.
