COMP & COMP-NW: Application Requirements

Application Process

Step 1: Prerequisites And Application Requirement

The first step in the admissions process is to ensure you are on track to complete both the course prerequisites and application requirements (see below) in time to apply for your preferred year of entry.

International Students: We do not require a separate application or fee, and you should be prepared to meet all of the prerequisite and application requirements as outlined. If you need assistance with immigration (I-20 form, F-1 visa, SEVIS, etc.), our International Student Services (ISS) staff are available to help you. Visit the ISS website to learn more.

Step 2: Make Yourself A Competitive Candidate

Admission to the program is competitive so you should strive to not only meet, but exceed the minimum requirements. To get an idea of the competitiveness of those accepted into the class, we recommend that you view our Competitive Class Stats page.

Step 3: Preparing And Submitting Your Application

The apply now page will provide you with step-by-step instructions as well as an application checklist.
