Chile: Pupil-teacher ratio, upper secondary

Key figures

What the numbers say

On record, the biggest yearly rise was 1.44 in 2013 and the biggest yearly fall was 1.25 in 2010. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2008 to 2017 the straight-line trend is downward, about 0.45 a year. A straight line explains 83% of the movement over 9 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 16.9 for 2020. We show this only because the same method, fitted on earlier years, predicted 2014 to 2017 better than "no change" would have: its average miss was 0.55, against 1.64 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

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.
