  • Some Schools and Networks Achieve Strong Results

    Some charter schools are independent; others are part of not-for-profit organizations that have unique philosophies and approaches that they use to operate multiple charter schools. The Knowledge Is Power Program (KIPP) is a network of charter schools that currently serves 70,000 students in 183 schools in 20 states. 

    Mathematica Policy Research’s 2013 study found that the average impact of being enrolled at a KIPP middle school on student achievement in math, reading, science and social studies is “positive, statistically significant, and educationally substantial.”

    The study found that after three years of enrollment in a KIPP middle school, students learn the equivalent of about 11 additional months in math than their traditional public school peers. In reading, students gain an advantage of 8 months of additional growth over three school years. In science, they gain a 14-month advantage, and in social studies, they gain an 11-month advantage.
