Overview of expertise examiners

Dear interested parties!


Here you will find all expertise examiners who are currently authorized to carry out expertise examinations on behalf of VDA-DGHT Sachkunde GbR. To contact an examiner, you can contact them by email. You can obtain the list by clicking on the "Inspector list" button (PDF file).


General information about examinations and certificates:


You will receive your certificate and your examination certificate after you have successfully completed the expertise examination. Both will be sent to you by the office.

If you have completed a skills test for a commercial area (so-called § 11 skills), you will receive the test certificate at the test site. The certificate will then be sent to you by the office.


If you have completed a purely theoretical dangerous animal training course (i.e. without a practical part), you will receive a certificate of participation from the office. You will only receive a certificate if you have completed both theory and practice.


Since April 2022, all certificates have been provided with security features and have a registration number. In the event of a loss, we can use the registration number to determine what type of proficiency test you have taken.


Please also note that creating and shipping can take up to four weeks! We endeavor to create all documents as quickly as possible, but would like to point out that the office is run purely on a voluntary basis and therefore all activities are carried out exclusively in our free time.


Always make copies of the certificates and the examination certificate. Your data will be completely deleted after a period of 10 years. Since VDA-DGHT Sachkunde GbR is a separate company of the VDA and DGHT associations, we do not pass on any data to the associations. We also cannot view any data from the associations.
