In this report, we present the results of a long-term tracking study that follows 1,177 students who applied to enter 1 of 13 oversubscribed KIPP middle schools through a 5th or 6th grade admissions lottery in 2008 or 2009. Those students are now old enough to have attended college for at least two years. This study uses a randomized controlled trial design to ensure that students who were offered admission to a KIPP middle school (the treatment group) are similar on average to students who did not receive an offer of admission (the control group) on both observable characteristics, such as prior test scores, and unobservable characteristics, such as levels of motivation and parental support.
