COMP & COMP-NW: Application Requirements

We use Acuity Insights to help us ensure we recruit only the highest-quality candidates for the highly-selective DO programs.

Acuity Insights has developed three assessments for evaluation of candidates for admission, CASPer, Snapshot, and Duet. The COMP and COMP-NW require that all applicants take the CASPer assessment. It should be taken concurrently with completing the Secondary Application. Applications will not be considered complete and ready for review without a CASPer Report. For the application year 2023-2024 COMP-Northwest has also chosen to trial Duet and is recommending that all applicants take the assessment. Duet will not be used in the decision process; its validity will be assessed against the data they collect.

Thank you for considering WesternU. Learn more about the application process and 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.

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