Chad: Repeaters, primary, total (% of total enrollment)

Key figures

What the numbers say

In 2016, Chad's repeaters, primary, total (% of total enrollment) fell 6.51 percentage points on 2015 (from 23.33% to 16.82%).

Across the 23 yearly changes before that (1977 to 2015), the average change was −0.15 percentage points and a typical year strayed about 2.04 percentage points from that (the standard deviation). This year's change was 3.1 standard deviations below that average, so it was unusually large compared with the rest of the record.

On record, the biggest yearly rise was 5.75 percentage points in 1995 and the biggest yearly fall was 6.51 percentage points in 2016. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2007 to 2016 there is no clear straight-line trend: a straight line explains 13% 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

Repeaters in primary school are the number of students enrolled in the same grade as in the previous year, as a percentage of all students enrolled in primary school.

Limitations: Country policies on repetition and promotion differ. In some cases the number of repeaters is controlled because of limited capacity. In other cases the number of repeaters is almost 0 because of automatic promotion – suggesting a system that is highly efficient but that may not be endowing students with enough cognitive skills.

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