I have recently changed my address/name/nationality. Do I need to inform the secretariat?

Address changes can be made by candidates themselves in the EQC portal.

For changes of the email address, please inform the Examination Secretariat by using the contact form.

In case of change of name or nationality a certified copy of the supporting document (e.g. marriage certificate or passport) is necessary.
