Shortages of qualified teachers in primary and secondary education are very common in almost all European countries and in the US. Since high quality teachers are usually the most likely to leave, much attention has been focused on teacher turnover; retaining the best teachers can help to ameliorate teacher shortages. Using data from the Survey of Health, Ageing and Retirement in Europe (SHARE), this paper examines the rates and characteristics of teacher turnover across European countries. Though the numerical rates of teacher turnover have followed similar patterns, countries are very individual in other respects, including the types of positions teachers hold and how they are appraised. Moreover, from the early 1990s, Eastern European countries experienced economic transitions that have influenced teacher mobility in the long term. Thanks to SHARE, we can study the occupational trajectories of respondents in nineteen European countries. By identifying those who changed their occupation, we can learn more about teacher turnover, its characteristics across Europe and how it has been affected by economic and political transition.
