The R score (cote de rendement au collégial or cote R in French) is a statistical method which classifies CEGEP students' academic performances in Quebec. It is used by Quebecois universities for selection purposes.
The R score is in fact a z-score to which has been added an indicator of the strength of the group (ISG). Since the z-score does not take into account characteristics specific to a student group, the inclusion of the ISG in the determination of the R score allows a more equitable comparison of students between themselves, regardless of their CEGEP's academic rank.
Most R scores range from 15 to 35; average marks result in a R score of 20 to 26.
