Public charter schools represent educational opportunity for millions of children across the country. Despite charter school growth and the overall importance of the sector, data on charter schools remains difficult to find and collect. That's why the National Alliance for Public Charter Schools took on this work — to serve as the eminent source of comprehensive data on charter schools. As leaders of the sector, we compile and thoroughly review data from multiple administrative sources, while accurately identifying and tracking charter schools to better reflect the unique environments in which they operate. The Knowledge Base is the first comprehensive compendium resulting from these efforts. Here you can find not only find data on the size and growth of the charter school sector over time, but also information on other important topics such as the student demographics, where charter schools are located, how charter schools are managed and governed, and other selected topics.
