Title:  Student Characteristics and Achievement in 22 KIPP Middle Schools
Description: The WWC quick review of the report "Student Characteristics and Achievement in 22 KIPP Middle Schools" reviews a study that examined the effect of charter schools in the Knowledge is Power Program (KIPP) network on reading and mathematics achievement in 5th- through 8th-grade students. The study analyzed scores on state assessments for more than 5,600 students who attended 22 KIPP middle schools in nine states and Washington, DC, in the 2000s. Students were followed for one to four years, depending on data availability, and the study standardized all test scores so they could be compared across states. Study authors found that students in the 22 KIPP charter middle schools examined had higher reading and math test scores, on average, than similar students in public middle schools. The WWC rated the research described in this report as meets WWC evidence standards with reservations because, although the study matched KIPP students to comparison students based on test scores and demographic characteristics, it is possible that differences existed between the two groups that were not accounted for in the analysis; these differences could have influenced achievement growth. In addition, the study examined each of the 22 KIPP schools separately, so cross-school conclusions should be interpreted with caution.
