In Switzerland there is a long tradition of the Dual Education System. From this it fallows that there are two possibilities to enter the workforce:
1) After nine years of primary and secondary school there is the possibility to do an apprenticeship in a company combined with a vocational education. The advantage is, that the student is an employee of the company from the beginning and receives tasks according to his growing abilities. There is a strong commitment of the companies to offer these apprenticeships and contribute to the education of young professionals.
2) There is the possibility to complete high school and college after the nine years of compulsory school. The advantage is the high education level of the students.
With this system, students can enter the workforce at different ages and there are more individual ways to form their skills.
