The city's public education system is composed of pre-schools, elementary and high schools (from grades 7 to 11), which are located in all of the city's districts and are under the supervision of the Ministry of Public Education. Nevertheless, private institutions do exist within the city. These educational institutions range from pre-schools to universities. Most tend to be bilingual, teaching subjects in either French or English and Spanish, among other languages, apart from just teaching a certain language.
