And more…

Teelen is the developer and supplier of TestVision. But Teelen is much more than that! It is our mission to help people in their personal development. This could be through teaching specific knowledge or skills, through testing or by creating conditions that allow people to develop.

Our test specialists are knee-deep in test clay every day. We advise, coach, train and certify organisations in education and beyond on test quality.
