From kindergarten to junior high, children follow our ROGY system (Blue, Red, Orange, Green, Yellow) — with the right track, ball and challenge at each level. It provides quick mastery, confident development and enjoyment of the game from the very first moment.

At Oslo Tennisklubb we use the international ROGY system to ensure that children develop in a safe, fun and age-appropriate way. Each level has the correct path size and ball type, so kids learn faster, move more, and experience early mastery.
The training is active, social and varied — filled with play, exercises and games that create real tennis enjoyment and a strong sense of mastery.
