Hundreds of Arizona's charter schools are facing accusations of not opening their doors to all students.
The American Civil Liberties Union of Arizona on Thursday said an investigation found the schools, which receive state funding, discourage enrollment of students with disabilities, English-learning needs and other vulnerabilities.
According to the report, roughly 260 schools out of more than 470 use discriminatory enrollment practices.
Among the allegations are that some schools limit the number of special education students or have no enrollment documents in Spanish.
The Arizona Charter Schools Association called the ACLU report a "hit piece."
In a statement, the organization says charter schools have always been open to everyone.
Arizona law states schools cannot limit admission based on certain criteria including disability, proficiency in English and income level.
