Hi. We are creating a new project with Vaadin. I’m hoping to test my team members’ skills by asking them to take your certification tests. I’d like to ask some questions. If someone fails in their first attempt, can they retake the test? How many times can they re-take the test? The free certification week is over, how much is the exam fees? I can’t find it on the web.


you should find answers to your questions and also the pricing at [url=https://vaadin.com/certification]


Thank you tepi. Sorry I couldn’t see the price before, the pop-up blocked it.
How many times can a candidate take the test after he pays. Can he re-take if he fails?


I got an answer from here. 5 times each time 30 days apart.
