q3 · i? · causal · r?

The Key Findings section reports a null achievement result for continuing KIPP students entering KIPP high schools; the summary restates that for this group impacts on achievement are "not statistically significant, on average." No effect size is printed, so the null is not evidence of equivalence.

"For students continuing to KIPP high schools from KIPP middle schools, impacts on achievement are not statistically significant."
