In Berlin, as in the rest of Germany, upon completing seven years of primary education, children and their parents choose between the following four kinds of secondary schools: Hauptschule (general secondary school), Realschule (secondary modern school), Gymnasium (which prepares students for university education) and Gesamtschule (comprehensive school). Parents may also choose to enroll their children in a unique school programme embedded in the European School (Europaschule), where pupils are taught in German and a foreign language, from primary school through secondary school. Additionally, four schools of classical study, known as Humanistische Gymansien, teach ancient Latin and Greek to their students. The Berlin-Brandenburg capital region is one of the major centers of higher education and research in the European Union. There are four universities and a number of private, professional and technical colleges throughout the city, altogether enrolling about 130,000 students, which have an international reputation in a variety of disciplines.
