COVID-19 and Observation Hours

Due to COVID-19, observation at our Oregon and SW Washington clinical affiliate locations is currently on hiatus until further notice. Review the updated 2020-2021 admissions observation requirements below. (Last updated 11/2/2020)

Steps to Apply to the Radiation Therapy Program

Step 1: Complete academic prerequisites

Review the list of Radiation Therapy Program academic prerequisites. The Radiation Therapy Program offers unofficial transcript reviews and advisement for all potential students. We encourage you to contact the Radiation Therapy Program  with any questions regarding acceptable prerequisites, or to set up a phone meeting with Program faculty.

Please review the program-specific and OHSU technical standards prior to applying to the program. 

Step 2: Complete 30 hours of observation

All applicants are required to spend 30 hours of observation time in radiation therapy departments. Applicants must also have a Documented Observation Form with them at the time of each visit. Please provide the form to a therapist from each observation clinic for completion after observation. Please request that the completed form be sent (scanned/mailed) to the OHSU Radiation Therapy Program.

All observation hours must be documented on the Completed Observation Form, and submitted with the application to the Program.

Contact information for program affiliated clinics in the Portland area may be provided by the program upon request. Please contact us at to obtain this contact information and supplemental HIPAA training module.

2020-2021 Admissions Observation Requirements:

We recognize that the majority of radiation oncology departments are not currently offering applicant observations due to COVID-19 precautions. This may result in difficulty obtaining the required 30 hours of observation.

At this time we request that when applying for 2021 admissions, applicants submit any hours observed, along with a brief statement of your efforts in acquiring any remaining observation hours. A lack of 30 hours of observation will not negatively impact your application for 2021 admissions.

Observation is a critical step in understanding the field of radiation therapy, and we recommend that each applicant spend time researching the radiation therapy profession to learn what the field entails.

Please reach out with any questions related to the application process and/or observation. We will communicate any changes in observation opportunities when available.

Step 3: Submit completed application between November 1st and February 1st

Documents needed to complete the application process:

  • Official transcripts
  • Completed Observation Form
  • Personal statement
  • Two letters of recommendation

In addition to OFFICIAL transcripts, please upload UNOFFICIAL transcripts from all colleges attended to the application for the initial review. Please submit official transcripts to:

Next Steps

After submitting a complete application, the following steps occur:

1.  Applicant Review

  • The admissions committee reviews all application documentation.

2.  Interviews

  • Based on the application review, a select group of applicants is invited to OHSU for on-site interviews. Interview day consists of tours, demonstrations, and a panel interview by the admissions committee. Note: Interviews may be conducted virtually in 2021.

3.  Admissions Decisions

  • All applicants are notified of admissions decisions. The program accepts up to nine students per cohort, and creates an alternate/waitlist. Admission decisions are based on a combination of application documentation and the interview.

Didn't get accepted this year? Apply the next year! The admissions committee looks favorably on applicants who apply again – particularly those who spend the year gaining experience in the field.

Acceptance from the waitlist

It is the policy of the OHSU Radiation Therapy Program to accept no more than nine students in an admission cycle. Applicants on the admissions waitlist will be accepted when an accepted student chooses to decline or defer their offer of admission, or otherwise cannot attend the program. The Radiation Therapy Program does not accept students off the admissions waitlist after July 31st of any given year for a Summer B Term start date.


The OHSU Radiation Therapy Program prepares students to pass the American Registry of Radiologic Technologists (ARRT) Radiation Therapy Examination, the national benchmark to practice in the United States. OHSU is unable to monitor requirements for licensure in every state, and therefore is unable to make a determination if an OHSU program meets all requirements for licensure for a given state. You should always check with the individual states for the current expectations regarding licensure in that state. Additional information regarding licensure can be found on the OHSU out-of-state authorization webpage under licensure.
