Conditions and Reregistration
You have three opportunities to appear for and pass any examination. Failure to accept an appointment, cancellation of an appointment, or failure to appear for a scheduled examination will be regarded as one of the three opportunities.
If you fail an exam or fail to appear as noted, you must submit a new registration, pay the fee, and retake the examination.
You will be notified by the ABR if you need to reapply.
Computer-Based Examination
Failures and Missed Opportunities
You may CHOOSE to take the Physics and Cancer Biology portions of the written exam after 36 months of training in radiation oncology, but taking the exams is not REQUIRED until the fourth year. If you take these exams before the fourth year of residency and pass only one, you will be required to repeat the one you did not pass.
In the fourth year of residency and beyond, you have three opportunities to appear for and pass the examinations (see above).
Conditions
If you fail one or two portions of the computer-based exam, you will be considered to have "conditioned" that exam.
You will have three consecutive opportunities to appear for and pass the examination. If, after three opportunities, you fail to pass the examination, you must submit a new registration, pay the fee, and retake all of the computer-based examinations.
You will be notified by the ABR if you need to do this.
Oral Examination
Failures and Missed Opportunities
For the oral exam, if you pass five or fewer categories, you have failed the examination. A candidate who fails the oral examination may be reexamined on the next year's scheduled dates.
Conditions and Reregistration
If you fail one or two categories, you are considered to have "conditioned" the exam. You will have three consecutive opportunities to be reexamined in the conditioned category(ies).
A conditioned candidate will be examined by two examiners in the conditioned category. The candidate must receive passing scores from both of these examiners to remove the condition.
If, after three opportunities, you fail to erase the conditions, you must submit a new registration, pay the fee, and repeat the entire oral examination at the next appointment.
You will be notified by the ABR if you need to do this.

Anyone who does reapply for an examination may submit that registration at any time. However, for a candidate to be considered for an exam in any given year, the reregistration form must be submitted to the ABR with payment prior to December 15 of the previous year.
Any candidate whose form arrives after December 15 will be eligible for the exam in two years. (Registraton forms received after December 15, 2009 are eligible for examinations occurring in 2011.)
