These are attended by about two thirds of the students and the first two are practically unknown in other parts of the world.[citation needed] A Gesamtschule largely corresponds to a British or American comprehensive school. However, it offers the same school-leaving certificates as the other three types—the Hauptschulabschluss (school-leaving certificate of a Hauptschule after 9th grade or in Berlin and North Rhine-Westphalia after 10th grade), the Realschulabschluss (also called Mittlere Reife, school-leaving certificate of a Realschule after 10th Grade) and Abitur (also called Hochschulreife, school-leaving certificate after 12th Grade). Students who graduate from Hauptschule or Realschule may continue their schooling at a vocational school until they have full job qualifications.
