The first 3 years of the Sciences Po Program are the most diverse as courses in Political Science, Economics, Public Law, History, International Relations and Sociology are taught as well as a minimum of two foreign languages. In the second year of the 3 year undergraduate Program IEP students are sent abroad as exchange students and as they come back, specialize in one of the three sections the IEP proposes in the 3rd year of its curriculum. Following the 3rd year, students must choose and be accepted into the masters program they desire - which lasts two additional years. Although some students leave the IEP at the term of their 3rd year, new students are admitted from other universities at the masters level.
