The aim of this study is to examine how the induction period for newly employed upper secondary school teachers is implemented in practice, in relation to the Swedish Education Act and the National Agency for Education?s general guidelines. Although this induction period has been legally mandated since 2010, both previous research and current statistics indicate significant shortcomings or wide variation in its practical execution. The study is based on a qualitative interview study involving 13 school leaders. The interview responses were analyzed using three complementary theoretical frameworks: Lipsky?s theory of street-level bureaucracy, Meyer and Rowan?s concept of decoupling, and Schein?s model of organizational culture.
