The three principal choices in primary and secondary education include home schooling, attendance at private schools, and attendance at public schools nearest the home. However, parents feel that more options are necessary, due to the inadequacy of particular public schools or the need for educational programs not offered in public schools. Thus, educators have proposed other programs, such as magnet schools, work-based attendance, and voucher systems. But magnet schools and work-based attendance provide little choice, and some educators fear that voucher systems would result in instability. Another schooling option is the open enrollment policy of the Minneapolis Public Schools, which offers a wide array of programs. This policy is most effective in a district with a large population.
