About Us

By Examiners, for Learners

ZertifikatDeutsch was developed by officially licensed examiners of the Goethe, ÖSD and telc exams. Our team consists of experienced German-as-a-foreign-language teachers and examiners who know the requirements of the various exam formats inside out.

We know the exam formats not just from theory, but from daily practice. This experience flows directly into our tasks and grading criteria.
