Context: Early-years education is quite common in Thuringia. Since the 1950s, nearly all children have been using the service, whereas early-years education is less developed in western Germany. Its inventor Friedrich Fröbel lived in Thuringia and founded the world's first Kindergartens there in the 19th century. The Thuringian primary school takes four years and most primary schools are all-day schools offering optional extracurricular activities in the afternoon. At the age of ten, pupils are separated according to aptitude and proceed to either the Gymnasium or the Regelschule. The former leads to the Abitur exam after a further eight years and prepares for higher education, while the latter has a more vocational focus and finishes with exams after five or six years, comparable to the Hauptschule and Realschule found elsewhere in Germany.
