Responsibility for educational oversight in Germany lies primarily with the federal states individually whilst the government only has a minor role. Optional kindergarten education is provided for all children between three and six years old, after which school attendance is compulsory for at least nine years. Primary education usually lasts for four years and public schools are not stratified at this stage. In contrast, secondary education includes four types of schools based on a pupil's ability as determined by teacher recommendations: the Gymnasium includes the most gifted children and prepares students for university studies and attendance lasts eight or nine years depending on the state; the Realschule has a broader range of emphasis for intermediary students and lasts six years; the Hauptschule prepares pupils for vocational education, and the Gesamtschule or comprehensive school combines the three approaches.Germany study in university :
To enter a university, high school students are required to take the Abitur examination, similar to A-levels; however, students possessing a diploma from a vocational school may also apply to enter. A special system of apprenticeship called Duale Ausbildung allows pupils in vocational training to learn in a company as well as in a state-run school. Most German universities are state-owned and charge for tuition fees ranging from €50–500 per semester from each student. Germany's universities are recognised internationally, indicating the high education standards in the country.
