In the fall of each academic year, NAPCS contacts state departments of education and charter support organizations to gather lists of anticipated new charter schools and lists of charter schools that closed the previous year. When state departments of education make official fall enrollment files available, NAPCS revises the lists to determine new and closed charter schools.
