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 Information for Applicants for Maintenance of Certification handbook.



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 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...
