This article presents statistics from a longitudinal study of attrition within the cohort of 87 Swedish teachers. The findings reveal that combining qualitative data with statistics in a longitudinal study on teachers’ career show that teacher attrition is a more complex and non-linear phenomenon than what is often proposed. The authors argue that the early leavers consist of a small and heterogenous group of individuals. Some of the reasons for attrition related to parental leave, Work overload, increased documentation and the notion of altered professional objectives.
