KIPP (Knowledge is Power Program) is a national network of public charter schools whose stated mission is to help underserved students enroll in and graduate from college. Prior studies (see Tuttle et al. 2013) have consistently found that attending a KIPP middle school positively affects student achievement, but few have addressed longer-term outcomes and no rigorous research exists on impacts of KIPP schools at levels other than middle school. In this first high-quality study to rigorously examine the impacts of the network of KIPP public charter schools at all elementary and secondary grade levels, Mathematica found that KIPP schools have positive impacts on student achievement, particularly at the elementary and middle school levels. In addition, the study found positive impacts on student achievement for new entrants to the KIPP network in high school. For students continuing from a KIPP middle school, KIPP high schools' impacts on student achievement are not statistically significant, on average (in comparison to students who did not have the option to attend a KIPP high school and instead attended a mix of other non-KIPP charter, private, and traditional public high schools). Among these continuing students, KIPP high schools have positive impacts on several aspects of college preparation, including more discussions about college, increased likelihood of applying to college, and more advanced coursetaking. This report provides detailed findings and also includes the following appendices: (1) List of KIPP Schools In Network; (2) Detail on Survey Outcomes; (3) Cumulative Middle and High School Results; (4) Detailed Analytic Methods: Elementary School (Lottery-Based Analyses); (5) Detailed Analytic Methods: Middle School (Lottery-Based Analyses); (6) Understanding the Effects of KIPP As It Scales Mathematica Policy Research; (7) Detailed Analytic Methods: Middle School (Matched-Student Analyses); (8) Detailed Analytic Methods: High School (Matched-Student Analyses); (9) Detailed Analytic Methods: High School (Matched-School Analyses); and (10) Detailed Tables For What Works Clearinghouse Review.
