Sudan: Pupil-teacher ratio, preprimary

Key figures

What the numbers say

In 2017, Sudan's pupil-teacher ratio, preprimary rose 0.48 on 2016 (from 25.36 to 25.84).

Across the 13 yearly changes before that (2002 to 2016), the average change was −0.08 and a typical year strayed about 6.12 from that (the standard deviation). This year's change was 0.1 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 7.86 in 2008 and the biggest yearly fall was 10.97 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 2008 to 2017 there is no clear straight-line trend: a straight line explains less than 1% of the movement over 9 observed years, so the value is moving around more than it is heading anywhere.

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

What this measures

Preprimary school pupil-teacher ratio is the average number of pupils per teacher in preprimary 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.
