The OSL is organised and run by the four Gauteng-based orienteering clubs, RACO, Adventure Racing Club, ROC and WITSOC. The league is aimed at learners from Grade 7 to Grade 12.
The Schools League runs annually in January, February and March which falls in term 1. Children are encouraged to join orienteering at a club level, which runs throughout the year on Sunday mornings. This improves their orienteering skills and makes them eligible for selection in the National SA Squad; they may be chosen to represent South Africa at the Junior World Orienteering Champs (JWOC).
