The vocational education in upper secondary school contains general and vocational subjects.Its aim is to give the students relevant vocational competence and employability. This study investigates the nature of didactical choices in vocational subjects as described bystudent teachers (future vocational teachers). Social cultural approach and pedagogic content knowledge (PCK) are used as theoretical perspective and analysing model, respectively. The analysis shows that the choice of content in vocational subjects is the specialised vocational content as it relates to the general content. Teaching also focuses on silent knowledge as a useful competence. In the pedagogical practice the student and the students’ needs are central for teachers´ choices of methods and also the approach. The vocational teacher emphasises that the students develop relevant and useful vocational competence. Employability is related to the student´s possibility to succeed in the coming profession.
