Arizona charter schools are supposed to be open to everyone. They can't discriminate against prospective students on the basis of gender, ethnicity, disability, or language proficiency. But as it turns out, some charter schools were ignoring state law. In a December 2017 report titled "Schools Choosing Students," the Arizona chapter of the American Civil Liberties Union revealed that a shocking number of charter schools use exclusionary enrollment policies. Families attempting to enroll their child in charter schools faced essays, interviews, requests for a birth certificate or Social Security number, and fees. Some schools asked whether the prospective student had a disability or special education needs, and others asked about the primary language spoken at home. The ACLU argued that these hurdles are unacceptable, and last spring advocates showed up to lobby the Arizona State Board for Charter Schools. Apparently, the board was listening. In June, officials reviewed enrollment policies and mandated changes at almost 100 charter schools. The ACLU says that more oversight is needed. Nevertheless, the campaign achieved an impressive outcome: a fairly quick response from a board that has been criticized for a laissez-faire approach to charter schools.
