The aim of this study was (1) to examine if people raised in different Christian religious movements have experienced a tension between the movement in question and the Swedish school system, if so, (2) how this tension was perceived, and (3) whether the tension have contributed to the decision to leave the movement. The study has been conducted through semi-structured qualitative interviews with six informants from four different religious backgrounds. The theoretical approach has been to analyse the tension aspect of Rodney Starks theory of church growth. Previous research about school discourses in religious education has been the base for analysing the school practice, while research on defectors experiences have been the base of analysing the informants’ experiences. The result shows that all informants have experienced a tension between the two contexts and that this tension is a contributing factor in their choice of leaving the movement. However, it seems that the movements views of the outside world are of more importance than the tension between the movement and the Swedish school.
