Language Requirements

English-Language Proficiency Requirements 

When you become a Western student, we want you to be successful. Part of that means making sure your English skills are strong enough so you can understand and enjoy your courses at Western. 

If English is not your first language, you must provide proof of your proficiency in listening, speaking, writing and reading English. Typically, this is done through an official test or English as a Second Language (ESL) program.

We reserve the right to ask anybody to provide proof of English language proficiency. If we need it from you, it will be on your To Do List on Student Center after you apply. Some students may be able to request an exemption or waiver.

Find additional details on acceptable proof of English proficiency.

Note: English-language proficiency requirements for admission to Undergraduate Nursing programs are different than the requirements for other programs at Western. For more information, visit the Nursing website.

Midterm and Final Grades

• If you do not have a grade in a prerequisite course, don't worry. We will review your application based on a combination of Grade 11 and Grade 12 grades available at the time of each offer round (provided your application is showing enrollment in prerequisite courses).
• You can log into your OUAC account to confirm proper submission of your grades and enrollment information.
• If you are registered to take a course outside of your home school, make sure it is a Ministry-accredited and approved school that offers the same rigorous curriculum and level of instruction as your high school. Grades must be reported through the OUAC.

Timing and Process for Admission Decisions

For Ontario Secondary School Students, we give offers in rounds from December to May. We will review your application in every single round.

We will use the combination of grade 11 and/or grade 12 grades we have available at the time of each offer round.

Typically, the last offer round is around mid-May. There is no disadvantage to getting an offer in the last round, so don't worry if you don't hear back early.
