What proportion of teachers leave the teaching profession?

This indicator analyses teacher attrition that is to say, the proportion of teachers (between pre-primary and upper secondary levels of education) leaving the teaching profession during their career. Several methods can be used to measure attrition, and this indicator focuses on an indirect measure of attrition, computing attrition based on the number of teachers in two successive reference years and the number of teachers who entered the teaching profession between these two reference years. This follows the method proposed by the Sustainable Development Goal (for comparability issues related to this method, see  for more information on other methods to estimate attrition, see ).
