Hoërskool Ooskus Gimnasium, historically known as Hoërskool Grens, is a co-educational public high school serving the Ooskus community of East London. The school has deep Afrikaans roots and remains closely connected to Laerskool Ooskus as its primary feeder. Ooskus Gim has a steady presence in Eastern Cape school sport, particularly in rugby, where its teams regularly face regional opponents such as Dale College, Queen's College, Hudson Park and Cambridge.
The school delivers the full CAPS curriculum in an Afrikaans environment with an increasing bilingual influence. Its sports programme covers rugby, hockey, netball, athletics and cricket, supported by a traditional campus with established fields and standard public-school facilities. Although smaller than many East London counterparts, Ooskus Gim’s identity is built around resilience, pride and a competitive edge that reflects its Grens heritage.
