A parent opens the quarterly report card, sees an average of 11.4 in mathematics and a general average of 12.8. First reaction: compare with the previous term. Second reaction: wonder why the score from the last test, which was good, didn’t raise the result more. The calculation of the school average remains unclear for most families, even though it is based on mechanisms that become accessible once laid out clearly.
Coefficient and weighted average: the mechanism that the report card does not explain
When you add up the scores in a subject and divide by their number, you get a simple average. This is the natural reflex. The problem is that most teachers do not assign the same weight to each evaluation.

A two-hour supervised test often counts more than a five-minute exercise collected in class. This weight is the coefficient. The actual formula becomes: sum of the scores multiplied by their coefficient, divided by the sum of the coefficients. If a test scored 8 has a coefficient of 3 and another scored 15 has a coefficient of 1, the average is not 11.5 but 9.75.
This explains why a “good grade” does not always raise the average as much as hoped. The coefficient of the failed assignment weighed more heavily. Many parents mentally reproduce the average calculation on Apprendissimo to verify what the report card displays, and sometimes notice a discrepancy with their initial estimate.

Discrepancy between the average displayed by Pronote and the average from the class council
School management software like Pronote or ÉcoleDirecte displays averages to parents, but these figures do not always reflect the reality discussed in the class council. Feedback from teachers for the 2024-2025 period indicates that some interfaces round results, hide diagnostic evaluations, or exclude assignments deemed insignificant.
The result: the average seen by parents and the one used by the teaching team can differ. A student displayed as having 12.3 on the family portal may be discussed in council based on an 11.8 that includes an assignment that the parental interface has excluded.
To avoid this confusion, you can ask the main teacher for the complete list of evaluations considered along with their coefficients. This is a document that families have the right to obtain. The ministerial guide accompanying the evaluation encourages institutions to make the criteria and methods for calculating averages clear in the documents provided to parents.
What you can verify yourself
- Count the number of grades displayed on the portal and compare it to the number of assignments the child mentions. A discrepancy indicates an evaluation excluded from the visible calculation.
- Redo the weighted calculation manually or with a spreadsheet, asking the teacher for the exact coefficients. If the result differs from the displayed one, ask the main teacher about it.
- Check if any evaluations are marked “non-significant” or “diagnostic”: they are sometimes removed from the displayed average but remain in the educational record.
Numerical average and competency assessment: reading the report card in full
In middle school, the report card is no longer limited to a column of numbers. The texts on the common core have introduced levels of mastery (insufficient, fragile, satisfactory, very good mastery) that coexist with grades. The class councils base part of their decisions on these levels, not solely on the average.
A student with an average of 10.5 in French but evaluated as “satisfactory” in text comprehension and “fragile” in written expression provides much more usable information than a simple number. The average aggregates everything, while competencies disaggregate. To identify where to focus efforts, it is the competency reading that guides the work.
How to combine the two readings
You start with the average to situate the overall level. Then you look at the competencies to pinpoint specific weaknesses. If the average drops from one term to the next but the competencies progress, it often indicates that one or two high-coefficient assignments have negatively impacted the result without the actual level having declined.
Feedback varies on this point depending on the institutions: some teachers incorporate competencies into the average calculation, while others treat them separately. Asking at the beginning of the year how the articulation works in your child’s class avoids unpleasant surprises at the end of the term.
Concrete method to recalculate the overall average of a report card
The overall average is not the average of the averages by subject. It is a weighted average where each subject weighs according to its own coefficient. Mathematics or French generally count more than music education or visual arts.
To recalculate:
- Take the average obtained in each subject and the coefficient of that subject (indicated on the report card or available from the administration).
- Multiply each subject average by its coefficient.
- Add all these products, then divide by the total sum of the coefficients.
- Compare the result with the overall average displayed. A discrepancy of a few hundredths comes from rounding, a larger discrepancy deserves a question to the institution.
This calculation takes a few minutes with a calculator or a spreadsheet. Redoing the calculation at least once per term allows you to anticipate trends rather than suffer them when reading the report card.
The school report card gains clarity as soon as we separate three readings: the average by subject for ongoing monitoring, the competencies for diagnosing gaps, and the weighted overall average for global positioning. None of these three dimensions tells the whole story on its own, but together they provide a reliable picture of a student’s progress.
