Radiation Oncology Examination Schedule

All ABPS written examinations are offered in a computer-based, multiple choice format in test centers across the United States, Puerto Rico and Canada.

The computer-based format allows the candidate great flexibility in examination scheduling, and in most cases, eliminates the need for long distance travel.

The computer-based examination window usually spans four weeks, and the candidate can schedule on any day during the four weeks that his/her chosen test center is open, and at any time during the day, so long as he/she allows enough time to complete the examination. Most test centers are open Monday through Friday only.  ABPS strongly suggests that you do not schedule your examination on a weekend, or a holiday.

Once a candidate is approved to sit for the examination, and the examination fee paid, ABPS will send the candidate a password and directions to registering for the examination on the date and at the test center of his/her choice.


Submission of an incomplete application may delay the board’s acceptance of your application in time for you to take the examination on the date desired.

At the end of the application, there is a checklist detailing the items required for attachment in order for your application to be considered complete. Please review the materials you are submitting against this checklist.

If after a period of one year from your submission of your application, all of the application materials are not deemed complete and the application has not been approved by the appropriate board of certification your application will become invalid, thereby requiring you to submit a new application and fee in order to pursue certification. You must meet the certification requirements, in effect, at the time the second or subsequent application is received by ABPS.

You do not submit an application for the oral examinations, only the fee. Oral examinations are typically administered on Saturday, and occasionally, on Sunday. Examinees are not permitted to take both the written and oral examinations during the same administration. Oral examinations are not required for every specialty.

Patient Care Is Our Priority

Medical organizations throughout North America understand that our rigorous certification standards prove that ABPS Diplomates are capable of delivering the best patient care possible.

I feel truly blessed and grateful to be an internal medicine board-certified diplomate with the American Board of Physician Specialties. Their ongoing, steadfast commitment to physician board(s) enhancement, forward focused vision, and tenacity is second to none. ABPS has become a recognized choice in Physician Board Certification.

To be the best, you must measure yourself against the best. Achieving Board Certification in Emergency Medicine by the ABPS gave me the opportunity to demonstrate mastery of the art of EM in an objective way. The high bar that ABPS sets for candidates to be allowed to take both the written and oral exam is a testament to ABPS's rigorous vetting of one's ability to practice Emergency Medicine at a high level. By maintaining these credentials, I've been able to instill confidence in my abilities at the department/employer level and ultimately with the patients that choose to seek emergency care at the facilities at which I practice.

The American Board of Physician Specialties has supported the entire field of Integrative Medicine in sponsoring our board. It has been so validating of the importance of prevention-oriented and holistic approaches to care while emphasizing the scientific basis of this specialty to have it recognized by ABPS. I am proud to have been one of the first groups to be board certified by ABPS in Integrative Medicine, leading the way for others committed to training in this specialty.
