The Swedish teacher training has since the end of the 20th century been affected by several extensive political reforms. The last reform, which was implemented in 2011,completly changed the teacher training. One of several implications of the reform was a return to a diversification of different teacher categories. The intentions of this diversification were, among others, to give each category of teachers specialized knowledge concerning their teaching subjects as well as the ages of their future pupils (based on a developmental psychology rationality), but also to attain stronger professional identities. The study is based on the Primary education teaching program with focus on the grades F-3 and 4-6. The empirical material consists of the assessment assignments given to the students in both programs. The aim of the study is to investigate what knowledge, knowledge forms and abilities that are assessed during the teacher training and consequently constructed as the teachers’ professional knowledge base. Bernsteinian theories on how power relations are produced and reproduced in and through the educational system is the main theoretical framework for the study. Pedagogic discourses, i.e. how the choice of content operates in the teacher training is also an important theoretical perspective. Another perspective in the analysis is how the knowledge and knowledge forms are represented in relation to horizontal and vertical discourses. The study finally tries to answer the question on how national policies are transformed into educational practice.
