Before that, children usually go to kindergarten, but it is not necessary. Students are separated depending on whether they speak French, German or Italian. At the end of elementary school (or at the beginning of middle school), students are separated according to their capacities and career interests in several sections. Students who aspire to a high school academic career (named Gymnasium or Kantonsschule) must be prepared for further study and maturity (usually obtained after 12 or 13 years of school at the age of 18/19). Students who intend to pursue trade or work complete only an additional 3 years before entering vocational education regulated by federal law and are based on private business cooperation that offers educational positions and public schools that offer compulsory free schooling to work educators. This “dual system” which is called splitting academic and vocational training has a continuation in the higher education system.
