From 2007 onward, urologists who become ABU certified, recertified, or subspecialty certified must enter Maintenance of Certification (MOC).  MOC is designed to evaluate the continued competence of a Diplomate.  MOC was developed by the American Board of Medical Specialties (ABMS) and its 24 member boards.  It has also been supported by the Accreditation Council for Graduate Medical Education (ACGME), the American Medical Association (AMA), the Federation of State Medical Boards (FSMB), and many other organizations.

The ten year MOC cycle, which culminates in recertification after completion of Level 4, has various requirements to be completed every two years.   A chart showing the requirements appears here.   The current Recertification process, applying to Diplomates originally certifying between 1985 and 2006 will be merged into Maintenance of Certification in 2018, as all time-limited Diplomates complete recertification.


Schedule and Fees:

In 2009, the Board implemented a $200 Annual Certificate Fee to streamline and replace all Recertification and Maintenance of Certification (MOC) fees.  The Annual Certificate Fee, payable by April 1, is charged to every ABU Diplomate who certified after 1985.


Application Documents:

Application documents for MOC Level 4 will be available via the above drop-down menu in December for those diplomates who are eligible to apply.  Information about the process is available in the handbooks.

The examination for recertification and maintenance of certification emphasizes clinical management. As many as 30% of the questions on the exam are derived from AUA Self-Assessment Study Program (SASP) booklets from the past 5 years. Another 15% of the exam questions are based on the AUA Guidelines.

The examination is the final component of Maintenance of Certification. It is taken after satisfactory completion of the other elements of the process. In 2017, the examination will return to a modular examination. There will be five modules: Core/General Urology, Oncology (includes urinary diversion), Andrology/Infertility/Erectile dysfunction, Female Urology/Incontinence/Voiding dysfunction and Calculi/Obstruction/Endourology/Laparoscopy. All diplomates will be required to take the Core/General Urology module plus one specific content module of their choosing. The core module will incorporate questions based on the AUA guidelines where possible. The proctored computerized examination will be administered at over 200 Pearson VUE testing centers located throughout the United States, Canada, and Puerto Rico.

The MOC exam is a 4 hour, 75 question examination covering the domains of urology.

The board will continue to identify those Diplomates who fail the MOC exam. However, due to the smaller number of exam items on the modular exam, the Board will identify a second group of Diplomates one Standard Error of Measurement (SEM) above the “pass point” for the exam. These will be designated as a ‘conditional pass” group. The latter group would be required to complete additional CME in the areas where they demonstrated low scores. After successful completion if the designated CME activity, recertification would then be approved. The “failed” Diplomates that score below the “pass point” will also need to participate in CME activities in their areas of deficiency and those will be discussed with the Diplomate. The “failed” Diplomates will the retake the MOC exam in the next year, retaking the same modules as taken in their initial exam. Those Diplomates who fail the exam on the second attempt will be offered an oral examination in Dallas the following year. This oral examination 26 will be structured toward the urologist in practice and not like the Certifying (Part 2) Examination with which all are familiar.


The MOC Pediatric Subspecialty examination is a 150 multiple choice question examination designed to assess knowledge in the field of pediatric urology.

The exam will include all aspects of pediatric urology, including but not limited to: congenital abnormalities, childhood acquired urologic problems such as tumors and trauma, and overlapping problems of adolescence.

The examination is a four -hour, proctored, computerized examination, administered at over 200 Pearson VUE testing centers located throughout the United States, Canada, and Puerto Rico.


The method used to determine a passing score on the recertification examination is based on criterion reference testing.  Criterion reference testing uses a benchmark examination to establish a performance which all candidates must meet.  Examinations are compared to the benchmark standard and the passing score varies according to the difficulty.  The probability of passing remains constant, and the examination process provides a uniform opportunity to pass from one year to the next.  In theory, all who take the examination could pass; there is no mandatory failure rate.  On average, approximately 98% of candidates pass the exam.


The American Board of Urology (ABU) is organized to encourage study, improve standards, and promote competency in the practice of Urology. The Board evaluates candidates who are duly licensed to practice medicine, and arranges and conducts examinations for the purpose of certification, subspecialty certification, recertification, and ongoing maintenance of certification. Certificates are conferred by the Board to candidates who successfully complete all requirements for a given certificate...
