Chilocco Indian School, which opened 85 years ago, has faced criticism for its treatment of students, including allegations of physical and mental abuse. The Bureau of Indian Affairs has investigated the school and is considering contracting its operation to a non-government agency. The school has grown significantly since its opening and now houses over 1,000 high school students on a 40-acre campus. The use of handcuffs to restrain unruly students is a controversial issue at the school.
