Mathematica Research on KIPP Schools
In 2007, KIPP commissioned independent
research firm Mathematica Policy Research to conduct a multi-year study of our
schools. We wanted to find out whether we were truly fulfilling our promises to
students and families, and to make that information publicly known.
Mathematica’s most recent report,
released in 2015, examines KIPP’s K-12 impacts as well as our middle school
impacts over time, in conjunction with our federal Investing in Innovation (i3)
Scale-Up Grant. The first two reports, released in 2010 and 2013, examine
impacts of KIPP middle schools.
Mathematica 2015 Report
Understanding the Impact of KIPP as it Scales
Released September 2015
In 2015, Mathematica released the report
from their five-year i3 Scale-Up Grant Evaluation of KIPP schools. This is the
first report ever to include KIPP schools at all K-12 levels, including
elementary and high schools as well as middle schools. The report also examines KIPP’s
middle school impacts over the past decade. View the report >
elementary schools have positive, statistically significant, and educationally
meaningful impacts on three of four measures of reading and mathematics skills.
with prior research, KIPP middle schools have positive, statistically
significant, and educationally meaningful impacts on student achievement in
math, reading, science, and social studies. Average impacts of middle schools
were positive and statistically significant throughout the 10-year period
covered by the study, though higher in earlier years than recent years.
high schools have positive, statistically significant, and educationally
meaningful impacts on student achievement for high school students new to the
KIPP network. For students continuing to KIPP high schools from KIPP middle
schools, impacts on achievement are not statistically significant. For this
group of continuing KIPP students, KIPP high schools have positive impacts on a
variety of college preparation activities and the likelihood of applying to
surveys of student motivation, engagement, behavior, and educational
aspirations, KIPP schools showed no significant impact. However, KIPP
elementary and middle schools had positive impacts on parent satisfaction.
