In the German part of the country, the situation is somewhat different. Sex education as a school implemented program is a fairly recent subject, the responsibility given to school teachers. Though federal structures give authority to each State to decide, there are efforts, notably under the auspices of "Santé sexuelle Suisse" - the Swiss branch of IPPF (International Planned Parenthood Federation) - to look for and propose possible models of application which take into account all factors of sex education according to their different levels of concern, parents, teachers, and external experts.
