This annual report on the charter school movement tracks student enrollment, growth, performance/accountability, the policy environment, and public opinion. Currently, 4,046 charter schools serve approximately 1,144,758 students in 40 states and the District of Columbia. The number of charter schools that opened in each of the past three years (between 400 and 450 per year) was noticeably higher than the average of the previous four years (340) and nearly twice as high as in the 2003-04 school year (260).
