The school was founded in 1961, as the earliest secondary school in the Tsuen Wan District. Today it is recognised as one of the leading schools in Hong Kong in terms of academic results. 11 September 1961 was a memorable day to TWGSS. On that day, TWGSS opened. The first campus site was in the newly established Hoi Pa Street Government Primary School, where sixty-eight boys and seventy-five girls were accommodated temporarily. In September 1963, however, due to the lack of classrooms available for S1-S3 levels, the school was separated into A.M. and P. M. session. 25 June 1964 was another meaningful day to our school because on that day, old boys and girls moved to the new campus and thus the whole-day school arrangement resumed. The opening ceremony of TWGSS was held on 25 November 1964. His Excellency the Governor, Sir David Trench, was invited to be the Guest of Honour to mark the opening of the school. A historical plaque of the grand opening ceremony can be found on the wall of the main lobby. It reads: "The school opened by His Excellency The Governor Sir David C.C. Trench K.C.M.G., M.C. on 25th November 1964." Two survivors of the 2010 Manila hostage crisis, who were orphaned by the tragedy, were students of the school.
Academic results
Historically, more students at the school have received 10 A grades on the Hong Kong Certificate of Education Examination than at any other secondary schools in Hong Kong. Out of over 572 secondary schools in Hong Kong, fewer than 30 have ever produced these so-called "10A" students. In particular, between 2000 and 2010, eight Tsuen Wan Government Secondary School students have received 10 A's in the Hong Kong Certificate of Education Examination and 14 students have received 9 A's, ranking ninth among all secondary schools in Hong Kong. In the Hong Kong Advanced Level Examination, more than 30 students have received 5 A's, 4 A's or 3 A's between 2000 and 2010. The school received a relatively high number of A grades and A-C grades per student. TWGSS counts a total of 12 winners of the Hong Kong Outstanding Students Awards, ranking seventh among all secondary schools in Hong Kong.
