Admission
Basic Requirements for Admission
If you have six Grade 12 U/M (4U/M) midterm grades or 3 final Grade 12 U/M (4U/M) grades, you will be considered for admission on a rolling basis beginning in February 2027. To be eligible, you must have six Grade 12 U/M courses, completed or in progress, including any program-specific requirements. Your application will be reviewed again once your second-semester midterm grades are received.
Note: Co-op courses are not included in any admission or final admission average calculations.
Admission to all programs requires the completion of English (ENG4U).
Failed and Repeated Courses
For students who have repeated up to 2 courses, the highest mark reported will be used in the calculation of the admission average. Students repeating more than 2 courses, or an individual course 3 or more times, may be asked to provide a letter explaining the need for the repeats. This information may be considered when determining admission. Courses completed after June 30 will not be included in the admission average calculation.
Timing and Process for Admission Decisions
Be sure to check the university's Admissions Tool for information and updates about the admission process, estimated cut-offs, enrollment targets, application deadlines and more. McMaster will begin making offers of admission at the end of February until early May on a rolling basis, based on a minimum of 3 final 4U/M grades and registration in sufficient 4U/M courses to a total of 6; or 6 interim and/or final 4U/M grades, including any required courses.
All offers are conditional upon completing the OSSD with at least six 4U/M courses and an acceptable final admission average, which will be specified in the offer of admission.
Notes:
- Most offers to the By-Selection Programs will be made in May. All of these programs require supplementary application information (except Midwifery, where an interview is part of the application process). Contact McMaster for details about application deadlines, timing of offers and more.
- We do not automatically make alternative offers of admission. Instead, we encourage you to apply to all of the McMaster programs you are interested in (up to 3). We will give full consideration to each program selection.
- We may not accept your application if you do not pay the OUAC application fee by the program deadline date.
