LibreOffice Certified Professional Trainers

LibreOffice Professional Trainers are individuals who have proven their ability in developing training programs for LibreOffice, at basic, intermediate and advanced levels. They are able to implement the Training Protocol provided by The Document Foundation (or a similar training strategy).

Therefore, they are able to interact with the LibreOffice project at any level, either directly through their contacts or through mailing lists.

The objective of Certified Professional Trainers is to help organizations or independent users to get to know and then become proficient in the use of LibreOffice, to gain a high level of productivity and user satisfaction.

Certified Professional Trainers should be TDF members, although membership is not a pre-requisite. They can be nominated by the Certification Committee for their activity, or they can apply for certification using the certification application form, and subsequently go through the peer-review process organized by the Certification Committee.
