In order to avoid penalizing students under exceptional circumstances for which they
are not responsible, the Ministère converts the results, which reduces the failure rate.
This procedure is applied to the results of all students who wrote the examination. All other marks are converted upwards, taking into account their original distribution. Since conversion is a procedure that is intended to correct exceptional situations, it is
used only on a small proportion of uniform examinations. Moderation involves comparing the school marks obtained by each group of students
(usually about 30 students) with the marks they obtained on the uniform examination. Moderation may thus adjust the school marks upwards or downwards. However, this
practice can never cause the failure of a student who would otherwise have obtained a
passing mark at school (before moderation) and on the uniform examination.
