The school has been famous since the 1930s, and in 1962, 1963, 1964, 1965 and 1966 concurrently, under the dedicated tutelage of late Mr Keong Snr, it rose to a new high with its boxing and rugby dominance over Singapore Boy's Town, Anglo-Chinese School, and Raffles Institution. Since the 1970s, the school has won the National championships consistently. The 1990s saw competition from Anglo-Chinese School (Independent) and Raffles Institution, but St Andrew's has had a major revival in the sport in recent years.
