Today I got the official notification of what I already knew unofficially. I am qualified to teach at the university. In other words, I received the certificate that is called University Teaching Qualification (or, in Dutch, BasisKwalificatie Onderwijs, BKO).
This certificate signifies that I have required pedagogical competencies to teach University students. Among others, I have shown that I can design new bachelor and master courses in a responsible way (and yes, I am using the design to teach my BSc course on automata & complexity theory). Also, I gathered enough proof to show that I can give lectures in a way that gets students engaged!
