Some special areas provide different paths. After attending any of the above schools and gaining a leaving certificate like Hauptschulabschluss, Mittlere Reife (or Realschulabschuss, from a Realschule) or Abitur from a Gymnasium or a Gesamtschule, school leavers can start a career with an apprenticeship at a Berufsschule (vocational school). Here the student is registered with certain bodies, e.g. associations such as the German Bar Association Deutsche Rechtsanwaltskammer GBA (board of directors). During the apprenticeship, the young person is a part-time salaried employee of the institution, bank, physician or attorney's office. After leaving the Berufsfachschule and passing the exit examinations set by the German Bar Association or other relevant associations, the apprentice receives a certificate and is ready for a career at all levels except in positions which require a specific higher degree, such as a doctorate. In some areas, the apprenticeship scheme teaches skills that are required by law, including certain positions in a bank or those as legal assistants. The 16 states have exclusive responsibility in the field of education and professional education. The federal parliament and the federal government can influence the educational system only by financial aid to the states. There are many different school systems, but in each state the starting point is always the Grundschule (elementary school) for a period of four years; or six years in the case of Berlin and Brandenburg.
