Eritrea: Pupil-teacher ratio, upper secondary

Key figures

Over five years it is down 24.84% from 36.77 in 2013 (5.55% a year on average, compounded). Since 1996 it is down 17.9% from 33.66 in 1996 (0.89% a year on average, compounded). The World Bank has no value for 3 of the years in between; the chart leaves those gaps open rather than joining across them.

What the numbers say

In 2018, Eritrea's pupil-teacher ratio, upper secondary fell 3.74 on 2017 (from 31.38 to 27.64).

Across the 15 yearly changes before that (1997 to 2017), the average change was −0.88 and a typical year strayed about 7.41 from that (the standard deviation). This year's change was 0.4 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 7.49 in 2003 and the biggest yearly fall was 16.95 in 2007. 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 downward, about 0.83 a year. A straight line explains 37% of the movement over 9 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.
