For this phase the sample was nearly doubled to 43 KIPP middle schools, including all KIPP middle schools open at the start of the study in 2010 for which relevant data could be acquired from local districts or states. → Christina Clark Tuttle 2013 q2 i? The report estimates achievement impacts for these 43 schools in science and social studies in addition to math and reading. → Christina Clark Tuttle 2013 (2)

q2 · i? · causal · r?

The executive summary states the evaluation "nearly doubled the size of the sample, to 43 KIPP middle schools", drawing on data from local districts or states for schools open at the study's 2010 start. No effect sizes are printed in the summary.

"For this phase of the study, we nearly doubled the size of the sample, to 43 KIPP middle schools, including all KIPP middle schools that were open at the start of the study in 2010 for which we were able to acquire relevant data from local districts or states."

q2 · i? · causal · r?

The summary states the report estimates achievement impacts for the 43 KIPP middle schools and broadens subject coverage: "includes science and social studies in addition to math and reading." No impact estimates are printed in the summary itself.

"This report estimates achievement impacts for these 43 KIPP middle schools, and includes science and social studies in addition to math and reading."
