CMA CHOI Cheung Kok Pre-vocational School is celebrating its 10th anniversary this year, with 148 students graduating.
Director of Education Lam Woon-kwong, who was guest of honour, praised the Chinese Manufacturers' Association for its contribution to education.
In the 1950s the association helped to lay the foundation of education in science and technology by donating millions of dollars for the construction of the Hong Kong Technical College (now Hong Kong Polytechnic University).
Mr Lam said that pre-vocational education is now recognised as an integral part of secondary school education.
Giving the students a word of advice, he encouraged them to read widely in their leisure time in order to improve themselves.
This year, the school had 148 graduates, 121 from Form Five and 27 from Form Seven.
In his address, school supervisor Patrick Choi Wan-hoe traced the school's development since it was set up in 1984.
