q2 · i? · causal · r?

First findings from a multi-year evaluation of the KIPP charter school network, comparing KIPP students to a matched comparison group. The report states impacts on state assessment scores in math and reading are "positive, statistically significant, and educationally substantial" for the vast majority of schools evaluated.

"Using a matched comparison group design, results show that for the vast majority of KIPP schools in the evaluation, impacts on students’ state assessment scores in math and reading are positive, statistically significant, and educationally substantial."
