Special Notice from Prometric Regarding COVID-19 (Coronavirus) >

Since the inception of the outbreak of COVID-19 in Wuhan China, Prometric (who administers the ABCGN Certification Exam) has been actively engaged in identifying and responding to the potential health risks it presents to its test takers, staff, and other individuals in the impacted areas.


Its responses have taken into account numerous perspectives, including local governmental policy and actions, information provided by global health organizations such as the World Health Organization (WHO) and the US Centers for Disease Control (CDC), corporate policies, and input from our testing partners and customers.


The Prometric Incident Management team will continue to monitor the situation around the globe and take proper future actions as needed. Please check back frequently for more updates regarding test center closings.


Test Center Actions


Candidate Safety


Candidates will be permitted to use medical masks and gloves while they are testing. Please note these items will be subject to visual inspection upon entry to the test center. For a full list of permissible items, please check here.


Test Center Cleanliness


We have fully reviewed all test center operations and continue to reinforce expected actions at all test centers around the world that will mitigate the risk of spread of the virus at these locations. These procedures include regularly cleaning high-touch surfaces (ex. test station keyboard keys, mouse, biometric touch chip device) and providing disposable wipes so that common surfaces can be wiped.


Protect Yourself!


  • Wash your hands frequently with an alcohol-based hand sanitizer or soap & water for at least 20 seconds.

  • Cover your mouth and nose with your elbow or a tissue while coughing or sneezing.

  • Avoid touching your eyes, nose, or mouth with unwashed hands.
