Estland: „Overall, teachers’ working conditions in Estonia include small class sizes, low student-teacher ratios and less teaching time than on average across OECD countries. Except at the pre-primary level, Estonia has some of the shortest teaching hours per year among OECD and partner countries, and they have fallen in recent years.“
