To align with the current state of COVID-19 precautions, we have amended our 2021-22 observation requirement. Applicants, please review the updated observation requirement below. -Updated 10/1/2021

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.


We recognize that the majority of radiation oncology departments are not currently offering applicant observations due to ongoing COVID-19 precautions. Observation at our Oregon and SW Washington clinical affiliate locations remain closed. This may result in difficulty obtaining 30 hours of observation.

At this time we request that when applying for 2022 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 2022 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 through our program website.

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

  • Official transcripts

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 individual and group interviews with the admissions committee. Note: Interviews will be conducted virtually in 2022.

3.  Admissions Decisions

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

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.

Refer to the Education site for Student Admissions Requirements and a comprehensive list of OHSU's approved academic policies:

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.

OHSU Employees as Students

OHSU employees seeking to pursue individual courses for academic credit or an academic degree or certificate within OHSU must declare their employment status to the Academic Program prior to registering for courses or accepting admissions.

OHSU students wishing to accept an employment offer from an OHSU department (excluding positions identified as Student Employment or Student Work Study) must notify their program director prior to accepting the position for the purposes of initiating the process to review conflicts of interest.
