Many school districts and states are examining parental choice as a means of improving public education. This document identifies various forms of school choice and describes existing programs across the United States. Within the public school system, choice programs fall into two basic categories--intra-district and cross-district. Intra-district programs include alternative schools, magnet schools, and open enrollment. Cross-district programs can be limited or comprehensive. Among the factors that facilitate effective choice programs are a clear statement of goals for all schools; parental information and counseling regarding school selection; fair and equitable admissions procedures; help for all schools to develop distinctive features; opportunities for teachers and principals to create programs; student transportation; requirements that state dollars follow students; and procedures that ensure racial balance. Tensions within the choice movement revolve around the issues of autonomy versus accountability, equity versus excellence, and diversity versus unity. Instead of asking whether or not school choice should be implemented, a more appropriate question would be: Could all constituents be offered more choices than they now have? (LMI)
