Controlled Open Enrollment
The Florida Legislature recognizes the value of an educational system that provides numerous and meaningful options for students and their parents. In order to promote parental involvement in the school selection process, the Florida Legislature enacted section 1002.31, Florida Statutes (Public school parental choice.–) to require each district school board to develop a plan that describes the controlled open enrollment public education delivery system that allows school districts to make student school assignments using parents indicated preferential school choice as a significant factor. The district school board must submit the controlled open enrollment plan to the Department of Education on an annual basis.
Each district school board may offer controlled open enrollment within the public schools in addition to the existing choice programs such as magnet schools, alternative schools, special programs, advanced placement, and dual enrollment. Controlled open enrollment emphasizes the rights for families to choose among existing public schools. Instead of being assigned to a public school by a school district based on attendance zones, parents may choose a school from anywhere within the district or, if not geographically feasible, from within established zones or boundaries within the district.
