About The Knowledge Base

Public charter schools provide educational opportunity for millions of students across the country, yet data on charter schools remains difficult to find and collect. The National Alliance of Public Charter Schools (National Alliance) is the eminent source of comprehensive data on charter schools. We compile and thoroughly analyze data from multiple administrative sources while also accurately identifying and tracking charter schools to better reflect the unique environment in which they operate. The Knowledge Base is our comprehensive compendium resulting from these efforts. Here you can find information on the size and growth of the charter school sector over time and other important topics, such as the demographics of charter school students, information about the location of charter schools, details on the management and governance of charter schools, and other selected topics.
