Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? Attending a KIPP charter middle school raises student test scores in reading, math, science, and social studies, with effects that are consistently positive and statistically significant. → Philip M. Gleason 2014
q2 i? KIPP middle schools produce significant achievement gains across four subject areas: reading, math, science, and social studies. → Various authors 2013
Evidence¶
Philip M. Gleason 2014¶
Philip M. Gleason, Christina Clark Tuttle, Brian Gill, Ira Nichols-Barrer, Bing-ru Teh. (2014). Do KIPP Schools Boost Student Achievement? Education Finance and Policy, vol. 9, no. 1. https://www.mathematica.org/publications/do-kipp-schools-boost-student-achievement doi:10.1162/edfp_a_00119
q3 · i? · causal · r?
The publication's own summary of the evaluation states that the study measured achievement impacts of "41 Knowledge Is Power Program (KIPP) charter middle schools nationwide" and found "consistently positive and statistically significant test-score effects" in all four subjects. No effect sizes or sample sizes are printed on the page.

q2 · i? · causal · r?
The brief's title states that KIPP middle schools produce significant achievement gains in reading, math, science, and social studies; the landing page provides no effect sizes, sample details, or test statistics, so the magnitude of the gains is not reported here.

- The second phase of the national KIPP evaluation nearly doubled the sample to 43 KIPP middle schools and estimated achievement impacts in four subjects — related
