WRO® International Final

Our international final is hosted by a different country each year. Delegations from all over the world travel far to participate in the competition and make new friends from other countries.

With so many member countries, the international final is a big event. Over 400 teams join the competitions, and this means over 2,500 people visit the event. Countless local volunteers make sure that the international delegations have the time of their life. And many of our national organizers bring experienced volunteer judges to help make the competitions possible.

WRO® Friendship Invitationals

The WRO® Friendship Invitationals are organized by different member countries each year. Friendship Invitationals are events where it is just as important to make new international friends and have fun as it is to compete in the WRO challenges. Invitationals are also meant to give more teams the opportunity to visit an international WRO event.

We had two successful first events in Philippines (2018) and Denmark (2019). We were planning to have three Invitationals in 2020, but unfortunately these events were cancelled because of the pandemic.

Because the Covid pandemic is ongoing, we have decided not to host any Friendship Invitationals in 2021. We trust that we will be able to organize a Friendship Invitational again after this year!

Our International Final is held in another country each year. And that means that it is one of our national organizers that takes on the responsibility to organize this amazing event. It is a good thing that they can usually expect a lot of support in their country. The events in Costa Rica (2017) and Hungary (2019) are a good example of this.
