Published R score thresholds
| Threshold type | R score | Term | Applicant category | Source |
|---|---|---|---|---|
| Required minimum R score | 25 | Fall 2027 (page consulted on 2026-10-26) | CEGEP applicants (Quebec) — pre-university DEC | Source |
| Minimum per subject | 26 | Fall 2027 (page consulted on 2026-10-26) | CEGEP applicants (Quebec) | Source |
Official Concordia wording: "Minimum cut-off averages" — published minimum cut-offs, to be used as indicators; the page specifies that the cut-offs can change depending on the applicant pool and that meeting the minimum does not guarantee admission.

Per-subject minimum published by Concordia (R score "mathematics"). Official Concordia wording: "Minimum cut-off averages" — published minimum cut-offs, to be used as indicators; the page specifies that the cut-offs can change depending on the applicant pool and that meeting the minimum does not guarantee admission.
Prerequisites
Basis of admission
- Pre-university DEC (2 years)
- Eligible technical DEC 420.A0/BO/AA (3 years)
Eligible DECs and their conditions
- 420.A0/BO/AA (eligible technical DECs)
Required prerequisite courses
- Calculus 1 (Calcul différentiel)
- Calculus 2 (Calcul intégral)
- Linear Algebra (Algèbre linéaire)
Admission is based on the indicated mathematics R score and on passing the listed courses within the DEC. Holders of an eligible technical DEC (420.A0/BO/AA) may be admitted WITHOUT the listed prerequisites; however, if the prerequisites were taken, a minimum of 26 in mathematics is required. Recognition of prior learning (advanced standing) possible.
Key dates
| Date | Deadline | Applicant category |
|---|---|---|
| November 1, 2026 | Application — winter entry (offered depending on the program; Concordia gives priority to applications submitted before the official deadline and considers late applications if seats remain) | CEGEP applicants (Quebec) |
| March 1, 2027 | Application — fall entry | CEGEP applicants (Quebec) |
If you're not eligible yet
- Overall R score below 25 or mathematics score below 26
- Missing prerequisites (Calculus 1, Calculus 2, Linear Algebra) — except eligible technical DEC
Official pathways
Missing prerequisites: admission possible, prerequisites to be completed
Concordia's official R score page indicates that applicants who are missing certain prerequisite courses may still be eligible for admission ("Applicants missing some of the prerequisite courses may still be eligible for admission"), while recommending completing as many prerequisites as possible at CEGEP. The missing prerequisites are then completed at university, depending on the program.
Extended Credit Program — 30 additional credits (mainly outside Quebec)
Extended Credit Program (ECP): 30 additional credits beyond the regular program. Published by Concordia mainly for applicants whose pre-university schooling is shorter than Quebec's (outside Quebec); for the BA/BEd and BSc programs, the calendar details the ECP's mandatory courses (mathematics, science, PSYC 205 for the BSc in psychology, etc.).
Mature Entry Program (without a DEC only)
Adult entry program (Mature Entry Program): at least 18 preparatory/supplementary credits in the absence of a DEC. Important official RESTRICTION for our audience: holders of a Quebec DEC or the equivalent are NOT eligible for mature entry (Undergraduate Calendar, section 14). This pathway is therefore intended for applicants without a DEC, not for CEGEP graduates.
No published pathway specific to the program beyond Concordia's general pathways opposite.
