Political parties are widely recognised as indispensable actors in democratic systems. One way to illustrate the actions and role of political parties is to explicate various party functions that may be carried out in a political system. The aim of this paper is to explore the relationships between the organisation of party education and five specific party functions in Sweden. The empirical material consists of interviews with party officials from all eight parties that were represented in the national parliament during 2018-2022 as well as a mapping of educational content, structure, and activities from various parties. This material has been analysed in relation to five concrete party functions and a theoretical approach that highlights interactions and relationships occurring on different levels in apolitical system. The results demonstrate that there are different relationships between party education and party functions which may generate implications that are important both for the agency of a party but also to the broader political landscape. It is also possible to discern one specific function related to the provision of party education, namely an affirmation function.
