Croatian language
Standard Croatian is the official language of the Republic of Croatia and, along with Standard Bosnian and Standard Serbian, one of three official languages of Bosnia and Herzegovina. It is also official in the regions of Burgenland (Austria), Molise (Italy) and Vojvodina (Serbia). Additionally, it has co-official status alongside Romanian in the communes of Carașova and Lupac, Romania. In these localities, Croats or Krashovani make up the majority of the population, and education, signage and access to public administration and the justice system are provided in Croatian, alongside Romanian.
Serbian language in Croatia
Most schools with instruction in Serbian are located in Vukovar-Srijem and Osijek-Baranja County in the area of former Eastern Slavonia, Baranja and Western Syrmia where rights on education in minority languages were provided during the United Nations Transitional Administration for Eastern Slavonia, Baranja and Western Sirmium based on the Erdut Agreement. Today with those schools there is also Kantakuzina Katarina Branković Serbian Orthodox Secondary School in Zagreb.
