Junior roller derby is a modified version of roller derby for children and adolescents, typically up to age 18, that emphasizes safety through a tiered skill system with varying levels of physical contact. Played on flat tracks, skaters learn essential skills like stopping and falling, progressing from no-contact levels to full-contact play as their abilities advance. The sport is facilitated by organizations like the Junior Roller Derby Association (JRDA) and aims to build athleticism, confidence, and teamwork in a fun, inclusive environment.
