According to the General Law on Education the teaching and learning in mother tongue for persons belonging to national minorities is provided; “In municipalities inhabited by persons belonging to national minorities traditionally or in substantial numbers the teaching and learning is being conducted in their minorities` languages.” When teaching and learning is conducted in minorities’ languages it is obligatory to also learn the official language. A school is obliged to offer a student that follow classes in a language that is not his or her mother tongue adequate assistance in teaching a language in which the teaching process is conducted in that school” ( Article 11 of the Law). Also, Article 13 of the Law on Minorities Rights and Freedoms anticipates the right, for persons belonging to national minorities, to education in their languages and to adequate representation of their languages in generic and vocational education, depending upon the number of students and financial resources in the Republic. These rights are being exercised in special schools and special classes in regular schools, at all educational levels. Article 14 of the Law on Minorities Rights and Freedoms defines that a class in which a teaching process will be conducted in a language and script of a minority can be formed for less number of students than the number planned to be in an institution, and it can not be less than 50% of the number of students anticipated with regulations in education areas.
