The charter school sector plays an important role in efforts to reform the education system and better serve the nation's public school students. To help understand this role, more than a decade ago the National Evaluation of Charter Middle Schools examined how admission to about 30 charter middle schools affected students' achievement. On…

This issue brief presents results of a long-term tracking study that follows 1,177 students who applied to enter 1 of 13 oversubscribed KIPP [Knowledge Is Power Program] 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…

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…

The Knowledge Is Power Program (KIPP) is a network of charter schools designed to improve the educational opportunities available to low-income families. KIPP schools seek to boost their students' academic achievement and ultimately prepare them to enroll and succeed in college. To achieve these objectives, KIPP schools leverage strong…

Recent federal policy initiatives are aimed at improving disadvantaged students' access to effective teaching. These efforts, including Race to the Top and the Teacher Incentive Fund, arise from concerns that disadvantaged students are taught by less effective teachers. A growing body of research uses value-added analysis to measure teacher…

This paper draws on data and experiences observing and analyzing school lotteries from the National Evaluation of Charter School Impacts (Gleason et al., 2010) to describe the challenges associated with lottery-based research. In that study, covering 36 charter middle schools in 15 states, we found that charter schools did not affect student…

As a condition of its i3 grant, KIPP contracted with an independent evaluator (Mathematica) to address a key research question: does KIPP maintain its demonstrated effectiveness as it scales? While this question sounds simple enough in theory, it poses several methodological and practical challenges. This paper outlines some of those key…

This paper presents findings from the first national randomized study of the impacts of charter schools on student achievement, which included 36 charter middle schools across 15 states. The paper compares students who applied and were admitted to these schools through randomized admissions lotteries with students who applied and were not…

The Knowledge Is Power Program (KIPP) is a network of charter schools designed to improve the educational opportunities available to low-income families. KIPP schools seek to boost their students' academic achievement and, ultimately, prepare them to enroll and succeed in college. This paper provides the most thorough analysis to date of the…

In this set of four supplemental tables, the authors compare the baseline test scores of the treatment and matched control group samples observed in each year after KIPP entry (outcome years 1 to 4). As discussed in Chapter III, the authors used an iterative propensity score estimation procedure to calculate each student's probability of entering…

Adding to the growing debate and evidence base on the effects of charter schools, this evaluation was conducted in 36 charter middle schools in 15 states. It compares the outcomes of 2,330 students who applied to these schools and were randomly assigned by lotteries to be admitted (lottery winners) or not admitted (lottery losers) to the schools.…

The Knowledge Is Power Program (KIPP) is a bold effort to create a network of charter schools designed to transform and improve the educational opportunities available to low/income families. KIPP schools seek to actively engage students and parents in the educational process, expand the time and effort students devote to their studies, reinforce…
