Are Charter Schools For-Profit? Charter schools choose their own management structure: 67 percent of all charter schools are independently run non-profit, single site schools; 20 percent are run by non-profit organizations that run more than one charter school; and just under 13 percent are run by for-profit companies.
Since the first enactment of charter school legislation in Minnesota in 1991, 43 states and the District of Columbia have adopted laws allowing charter schools. Alabama is the most recent state to allow charter schools. According to the National Alliance for Public Charter Schools, there were 5,997 charter schools in the 2012-2013 school year, making up 6.3 percent of all U.S. public schools.
