The Knowledge Is Power Program (KIPP) is the nation's largest network of public charter schools. KIPP began as a network of charter middle schools designed to serve underserved communities, with the goal of closing achievement gaps and preparing students to succeed in college. KIPP has since expanded its model to include elementary and high schools in most regions, and expanded its goals to include preparing students to persist in multiple postsecondary pathways. In this report, we present the results of the second phase of a long-term tracking study that follows 2,066 students who applied to enter 21 oversubscribed KIPP middle schools through an admission lottery in 2008, 2009, or 2011. [For the first phase study "Long-Term Impacts of KIPP Middle Schools on College Enrollment and Early College Persistence," see ED603636.]
