Frequently asked questions
Below are frequently asked questions from students applying to Perimeter Scholars International. Please carefully read through these questions and answers before emailing PSI for any other inquiries.
Is there an application fee?
There is no application fee.
Will I get scholarship funding?
Successful PSI applicants may receive funding as described in the Financial Support section. Applicants are also encouraged to seek out and apply for externally available scholarships.
When are the application deadlines?
There are two deadlines:
- Deadline for early consideration — December 1st at 11:59 EST
- Deadline for final consideration — February 1st at 11:59 EST
Why are there two deadlines?
Having two deadlines allows for us to accommodate consistently with graduate schools internationally. Those who do meet program requirements from the early deadline will be moved into the final selection stage in February. There may be a few offers made in December or early January to exceptional applicants.
Which deadline should I apply for?
We encourage all eligible applicants who meet the required criteria to apply for the early deadline. However, applicants whose information may significantly change by the second deadline in February should not apply for the early deadline.
Will applications be considered after the final deadline?
We cannot guarantee consideration of late applications. However, we do accept late submission of the ELP scores (TOEFL, IELTS, C1 Advanced, C2 Proficiency) if these are unavailable by the deadline.
What are my chances of being accepted into the PSI program?
We are unable to tell you via email what your chances are of being accepted into the PSI program. Each year, we receive several hundred applications for approximately 25 available positions. Some offers will be made in December or early January, and some early applicants will be reconsidered at the final deadline.
