Declared open by Prime Minister Mr Lee Kuan Yew on 18 July 1964, Serangoon Garden Technical School (a secondary school) was the third technical school founded in Singapore. Its first intake consisted of 1,002 students drawn from both the Chinese and English stream. In 1969, it became a purely technical school and since 1972, it functioned as a single-session school with remedial lessons and extra-curricular activities held in the afternoons. Due to the shrinking number of Chinese stream students, the school offered its final batch of ‘O’ Level Chinese Stream candidates in 1983. The school stopped offering technical subjects in 1990 and merged into Serangoon Garden Secondary School in 2003.
