Mathematica Study on KIPP Middle Schools

Mathematica logo

KIPP has a longstanding commitment to performance transparency. We rigorously examine our performance data to understand our impact —what is working and what needs to be improved —so that we can better serve our students, and fulfill our commitment to continuous learning and improvement.

In 2008, Mathematica Policy Research began a multi-year longitudinal study of KIPP middle schools. Mathematica has released two reports to date, in 2010 and 2013, along with two installments of a working paper. The report released in February 2013, is the latest and most comprehensive look at KIPP schools to date

This report showed that (1) KIPP middle schools made significant gains in reading, math, science, and social studies across all grades; (2) The magnitude of KIPP’s achievement impacts is substantial. Mathematica found that students showed gains equivalent to an extra 8 months of learning in reading, 11 months in math, 14 months in science, and 11 months in social studies; and (3) Mathematica’s research included a test of higher thinking skills, which students could not have prepared for in advance. On this exam, KIPP students showed substantial gains in all tested subjects and across all grades-demonstrating that KIPP’s gains could not be explained by teaching to the test.

By engaging in rigorous research and evaluation, we hope to promote continuous improvement within our network and serve as leaders in demonstrating what’s possible in public education for children from underserved communities. The final Mathematica report on KIPP will be released in 2015.
