About Florida’s Charter Schools
Charter schools are public schools of choice. They are very popular—and among the fastest growing school choice options in Florida. Charter schools are largely free to innovate, and often provide more effective programs and choice to diverse groups of students.
Since 1996, the number of charter schools in Florida has grown to over 400 in 2010. Charter school student enrollment has grown well over 175,000 students.
