Two million students now attend charter schools, a 13 percent increase in one year, according to the National Alliance for Public Charter Schools. More than 400,000 students remain on wait lists.
Over 500 new charter schools opened this fall, raising the total to 5,600 schools.
Some 150 public charter schools closed for reasons that include poor performance, low enrollment and financial problems.
