Croatian i/kroʊˈeɪʃən/ (hrvatski [xř̩ʋaːtskiː]) is the standardized variety of the Serbo-Croatian language used by Croats, principally in Croatia, Bosnia and Herzegovina, the Serbian province of Vojvodina and other neighbouring countries. It is the official and literary standard of Croatia and one of the official languages of the European Union. Croatian is also one of the official languages of Bosnia and Herzegovina and neighbouring countries. Education system Primary and secondary education is essentially free because it is mostly sponsored by the Ministry of Education of the Croatian Government. Higher education is also mostly free because the government funds all public universities and allows them to set quotas for free enrollment, based on students' prior results (usually high school grades and their result at the set of exams at enrollment). Social political stand points Croatian, although technically a form of Serbo-Croatian, is sometimes considered a distinct language by itself Purely linguistic considerations of languages based on mutual intelligibility (abstand languages) are frequently incompatible with sociopolitical conceptions of language so that varieties that are mutually intelligible may be considered separate languages. Differences between various standard forms of Serbo-Croatian are often exaggerated for political reasons. Most Croatian linguists regard Croatian as a separate language that is considered key to national identity.
