I and II level of accredited professional studies at Higher Business School of Professional Studies in Leskovac are realized in Serbian language.

Office for projects and international cooperation will organize all activities and offer help related to language preparation of students. Language Coordinator will, when needed, organize a preparatory (basic) language course for incoming students and will be available for any kind of support and assistance in the duration of their mobility. The aim of basic language course is for incoming students to be independent in communicating in Serbia and attend lectures and practice classes organized in Serbian.

Each student participating in an outgoing mobility must meet a number of requirements including those related to language and communication skills. Serbian students start learning English language in elementary schools and English language is one of the courses that students attend at the first level of studies at HBSL. A certain number of students at the first level of studies at HBSL learn both French and English language. Language Coordinator with the Office for projects and international cooperation at HBSL will conduct foreign language placement tests in the process of selecting mobility students. Students selected for outgoing mobility can attend free, additional foreign language training and a type of cultural preparation depending on the country to which students are going within their mobility program which the Coordinator organizes (when needed).
