OECD members: Pupil-teacher ratio, upper secondary

Key figures

What the numbers say

In 2018, OECD members' pupil-teacher ratio, upper secondary rose 0.07 on 2017 (from 13.29 to 13.35).

Across the 25 yearly changes before that (1993 to 2017), the average change was −0.02 and a typical year strayed about 0.18 from that (the standard deviation). This year's change was 0.4 standard deviations above 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 0.53 in 2013 and the biggest yearly fall was 0.4 in 2000. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2009 to 2018 the straight-line trend is upward, about 0.03 a year. A straight line explains 32% of the movement over 10 observed years.

What this measures

Upper secondary school pupil-teacher ratio is the average number of pupils per teacher in upper secondary school.

Limitations: The comparability of pupil-teacher ratios across countries is affected by the definition of teachers and by differences in class size by grade and in the number of hours taught, as well as the different practices countries employ such as part-time teachers, school shifts, and multi-grade classes. Moreover, the underlying enrollment levels are subject to a variety of reporting errors.

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