The education system in Switzerland is very diverse, because the constitution of Switzerland delegates the authority for the school system to the cantons (Article 62). The Swiss constitution sets the foundations, namely that primary school is obligatory for every child and is free in public schools and that the confederation
can run or support universities. Swiss people have voted on May 21, 2006 to reform the education system in one common program for all the cantons. Because of its diversity, there are many private international schools in Switzerland that encourage respect for all cultures.
