The Certifications menu item under Achievements in the Avendoo frontend provides users with an overview of all certifications they have obtained as part of their learning activities. Certifications officially document completed qualifications or learning objectives and can serve as important evidence for professional or personal development. Certifications can be valid either indefinitely or for a limited period. If a certification expires, you will be notified accordingly in this area. In addition, the history of renewed certifications can be viewed at any time.
