France has a wide range of institutions offering tertiary education. The state operates the university system, but there are also private universities run by the churches, as well as several private international schools such as the American University of Paris.
Classes in French schools are held primarily in French. Many Universities do however have departments offering one or two year programmes in French as a foreign language to bring students up to a fluency in French which will allow them to enter a degree or diploma programme.
French Universities offer diplomas, while only the State itself awards degrees. There is a gradual move towards the more normal degree system with the state expanding its field of degrees, but most institutions still offer a complex mix of diplomas, depending on the field of study. Many diplomas still do not have equivalent degree recognition.
These are offered in most fields, including art.
The great majority of French programmes at all levels include a one-year relevant work-placement, in France or overseas, called le stage. More prestigious institutions often work in conjunction with overseas universities to offer exchange programmes during le stage. So a way to spend a year studying in France at a top school is to enrol in such a programme at a university in your own country.
