What do our customers think?

Andrew Smit, Hogeschool Inholland

“During the implementation, Teelen was more than a supplier. They felt more like a partner, always ready to listen. Ready to jump into action and always willing to discuss the things we needed.”

Henk van der Meijden, Stipel

“Teelen has supported us in further professionalizing our theory exams. They are also helpful in professionalizing our practical exams.”

Alwin van Attikum – Wullink, Saxion

“Throughout this process, we came to know you as a reliable partner who actively thinks along with us in every possible way. Together, we achieved a great result and the implementation went smoothly. In the very first academic quarter after go-live, we successfully delivered nearly 15,000 tests over a two-week period — without a single issue. A successful exam period!”

Patricia Jonkers, Rabobank

“We experienced the implementation of TestVision as very pleasant. What we especially appreciated was how quickly the process moved forward. The preparation was thorough, and it was clearly communicated what was needed from our side to ensure everything ran smoothly.”

André Bremers, iVTG

“The collaboration with Teelen was in both legal, financial, and educational areas. The technology worked flawlessly from the start.”

Sandra Wiechers, Politieacademie

“Thank you so much for the nice cooperation! It is good to see how you operate as a company, so honest, open and energetic. The passion radiates from it. In this day and age this is unfortunately a rarity.”
