The primary and secondary education is subdivided into four stages: preschool education, primary and low secondary education, high secondary education and special education. Preschool education is for children from the ages of one to five. Primary and secondary education is obligatory for everyone. It is provided by gymnasiums and vocational schools and also available in languages of recognised minorities in Kosovo, where classes are held in Albanian, Serbian, Bosnian, Turkish and Croatian. The first phase (primary education) includes grades one to five, and the second phase (low secondary education) grades six to nine. The third phase (high secondary education) consists of general education but also professional education, which is focused on different fields. It lasts four years. However, pupils are offered possibilities of applying for higher or university studies. According to the Ministry of Education, children who are not able to get a general education are able to get a special education (fifth phase).
