China-based testing update

In response to the Coronavirus outbreak and as a precautionary measure against the spread of the outbreak, Pearson VUE is temporarily closing its China-based testing centers and suspending exam delivery through our third-party, China-based test center network effective January 27, 2020 to ensure the health and safety of testing candidates and Pearson VUE employees.

At this time, our intention is for exam delivery within these locations to remain suspended through February 2020, in alignment to the guidance provided by local authorities, the World Health Organization, and others. However, we will continue to monitor the situation and act upon any new guidance provided related to the safety of our candidates and employees.

All exams originally scheduled to be taken within this timeframe have been cancelled by Pearson VUE and candidates will receive a full refund.
