- More than one-third of male primary school teachers in OECD countries are now over 50 years old.
- Across OECD countries, the average age of secondary school teachers has increased by one month every year in the last decade.
- Only a few countries have managed to develop policies which lower the average age of teachers significantly.
- Increasing the numbers of female teachers no longer lowers the average age, as the female teaching workforce is ageing faster than its male counterpart.
