Finnland: „When new teachers are employed in a school, they usually stay there for life. Very few primary school teachers leave their work during the first 5 years, and attrition is much less common than in other countries. An official estimate suggests that only 10 % to 15 % of teachers leave the profession during the course of their career.“
