Yes, you can. In the position of a judge or an observer. All you have to do is to fill out and submit to us online registration form. All information regarding that can be found here:

In case you are a debater without a team, you can write to registrations@heart-of-europe.org and we will attempt to find you teammates.

Each team must have the minimum of 3 members in the position of debaters. The top limit is not strictly defined, but we do not recommend more than 5 debaters per team. If you have six debaters or more, it is generally better to split them into two or more teams. Take note that each delegation must also bring n+1 judges with them, where n is the number of teams in the delegation. Should you bring less judges than that with you, you will have to pay extra fee.

Each team must also have an adult with them who is responsible for them.
