ARDMS Examination Testing

Take your exam from home. Simply choose 'Online at my home or office' when presented with exam options. Learn more about OnVUE.

OnVUE testing is currently available for select ARDMS examinations. Please check the ARDMS website for further information.

It is your responsibility to review the technical requirements to ensure your system is compatible with the online proctoring software. If your system does not meet the requirements and causes a problem during the examination, you will have to reschedule at your own cost. Additionally, when choosing the online delivery option, ARDMS candidates accept all responsibility for the testing environment and ensuring all requirements are met. Be advised that while your device may pass the system check, your device may still not function properly once the examination is downloaded. If your examination is revoked for any reason, as noted by Pearson VUE, this will result in the candidate needing to submit a new online application and payment. If you are concerned about these requirements, candidates are encouraged to test in a Pearson VUE test center.
