Regulations

In addition to the game rules for our different challenges we have a set of "General Rules." These tell you everything you need to know about participating in a WRO competition. The General Rules state what is permitted and what is not permitted in the WRO competition. If you participate in the competition you should read them to avoid problems.

You can download the General Rules here.​​​​​​​ 

Age Group Definitions

Compete with peers

In WRO we have the ambition of being relevant to students of different ages. That is why we offer competitions on platforms that provide fun and challenging experiences.

It is also why we have devided two of our categories into three age groups. In the Regular Category, each age group has a different mission. In the Open Category, the challenge is the same for all participants, but they are judged within their age group.

Please note:

The mentioned ages reflect the age of the participant in the year of the competition, not at the competition day. For participation in the international WRO final it is strictly enforced that students cannot, at any time in the year of the competition, be older than specified in the age group definitions. Example: A participant that is still 12 years old at the time of the international WRO final in November, but turns 13 years old in December the same year cannot participate in Elementary Category.

For more details please look at the General Rules.

Table of Eligibility (TOE)

Qualification for the international final

Only teams that participated in a national competition in one of our member countries can qualify for the international final. The WRO Table of Eligibility (TOE) defines how many teams a WRO National Organizer can register for the international final.

  • The number of teams a National Organizer may send to the international final depends on the number of teams in the national competition.
  • Each competition category has its own TOE. 
  • A country has to have minimum 5 teams in a competition category to register teams for the international WRO final for that category.
  • A team may participate in only one competition; Regular Category, Open Category, WRO Football or Advanced Robotics Challenge.
  • Any student may participate in one team only.
  • The numbers in the tables are maximum per age group and category and cannot be transferred from one age group or category to another. National Organizers may register fewer teams than allowed, but never more. 
  • In Regular category, if a country does not compete in a certain age group, it is not allowed to swap teams around. (For example: If you have 5-99 teams and you don't compete in Senior age group, it is not allowed to bring 1 Elementary and 2 Junior teams.)
