OECD members: Trained teachers in preprimary education (% of total teachers)

Key figures

What the numbers say

In 2022, OECD members' trained teachers in preprimary education (% of total teachers) fell 0.51 percentage points on 2021 (from 88.61% to 88.1%).

Across the 16 yearly changes before that (2006 to 2021), the average change was −0.2 percentage points and a typical year strayed about 1.23 percentage points from that (the standard deviation). This year's change was 0.2 standard deviations below that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 3.55 percentage points in 2006 and the biggest yearly fall was 1.6 percentage points in 2020. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2013 to 2022 the straight-line trend is downward, about 0.76 percentage points a year. A straight line explains 97% of the movement over 10 observed years.

Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.

A straight-line projection, tested first

Extending that straight line gives about 85.72% for 2025. We show this only because the same method, fitted on earlier years, predicted 2020 to 2022 better than "no change" would have: its average miss was 0.73%, against 2.32% for assuming no change. Treat it as a continuation of the recent pattern, not a forecast of events: it cannot see a recession, a policy change or a revision to the data.

What this measures

Trained teachers in preprimary education are the percentage of preprimary school teachers who have received the minimum organized teacher training (pre-service or in-service) required for teaching in a given country.

Limitations: This indicator does not take into account differences in teachers' experiences and status, teaching methods, teaching materials, and classroom conditions - all factors that affect the quality of teaching and learning. Some teachers without formal training may have acquired equivalent pedagogical skills through professional experience. In addition, national standards regarding teacher qualifications and pedagogical skills may vary.

Regional and income-group figures are computed by the World Bank as a weighted average.
