Repetition rate in indicators more closely follows the percentage of repeaters

[Ghislain Hachey]

I think the repetition rate of the EMIS indicators dashboard is more like the Percentage of Repeaters indicator than the Repetition Rate.

Percentage of Repeaters: Total number of pupils who are enrolled in the same grade as in a previous year, expressed as a
percentage of the total enrolment to the specified grade. Since VERMPAF is build from enrol & PupilTable → tableEnrol → enrolmentRatios the raw source of repeaters is really the “Total number of pupils who are enrolled in the same grade as in a previous year”.

Repetition Rate: Proportion of pupils from a cohort enrolled in a given grade at a given school year who study in the same grade in the following school year. This one technically requires data for two consecutive years. We do it when producing “flow” indicators dividing the Repeaters of Next Year by the Enrolment of this Year. It is typically a by grade indicator. Probably should eventually check the repeat rate in the individual school chart to see what this actually does and clarify there too.

At a minimum for now I think perhaps renaming this in the Indicators dashboard to avoid future questions on these indicators.

A consequence of the definition of repetition rate is that it is an indicator for the BASE year;

ie

RepRate 2022 is the percentage of enrolment in 2022 who repeated in 2023.

So you cannot calculate the RepRate for 2022 until you have the 2023 census.

So when you re displaying a page of indictors for 2023, you will display what is by this defintion the 2022 RepRate.

One thing I have done to explicate what is going on is to describe the repetition rate indicator

as RepRate 2022=>23

which makes it obvious the years we are talking about.

Note the drilldown on the Indicator page ('Click to explore repetition rate') has a detailed explanation

With drill down by gender, grade, school:
