Charter schools are well positioned to serve the needs of English Learner (EL) students, but need to be aware of the legal parameters governing public education of ELs. The greater flexibility afforded to charter schools offers opportunity to develop innovative approaches to providing ELs, one of the fastest growing demographic groups among students in the United States, with a quality education. But as charter schools are still subject to all federal and some state education laws, charter schools must understand their legal obligations to EL students. This report, co-authored by Safal Partners and Public Impact for the National Charter School Resource Center, examines federal requirements under civil rights laws and the Elementary and Secondary Education Act, and state laws governing charter school recruitment, retention, enrollment of EL students and their accountability for EL student performance; requirements and current challenges related to EL data reporting; and whether existing laws are adequate to address the needs of this growing population of ELs in charter schools.
