The aim of this study is to examine children's beliefs with regard to their agency (i.e., to know and predict your own actions and the consequences of them), in different contexts (family, school and peer-situations). Interviews were conducted with 103 ten-year-old Swedish children. Vignettes were presented to the children and their answers were written down for subsequent thematic analysis. Children think of their agency differently depending upon which context they find themselves in. The contexts where children believe most in their agency are found in situations with peers, and the contexts where they believe least in their agency are experienced with teachers. In situations with parents children think they would react with more resistance than with peers and teachers.
