In WRO, there are the following age groups (valid for 2024):
Age group | Age | Years of birth |
---|---|---|
Elementary | 8 to 12 years old | 2012 to 2016 |
Junior | 11 to 15 years old | 2009 to 2013 |
Senior | 14 to 19 years old | 2005 to 2010 |
Starter (Starter Category only) | 6 to 10 years old | 2014 to 2018 |
The deciding factor is the year when a participant was born, not the age they happen to be on the date of the competition.
