The school was started on 9th August 1909 as a pure Technical School providing a 3 – year course in Woodwork and Metalwork. It was then called Accra Technical School and was sited at the current site of Kimbu Secondary Technical School, Accra. It was founded in response to the growing demand for technical education at that time and its purpose was to train artisans to man the essential service of the Gold Coast i.e. Transport and communication, Public Works Department and Electrical Supply Commission.

It was transferred to Takoradi in 1939 and later sent to the Elmina Castle in 1940. It was however closed down in 1941 because of the 2nd World War.
This was to give way to the Royal Air Force to use the school. It was reopened in 1947 in Takoradi at its present site. In 1953, the school became Government Secondary Technical School. It however became government assisted in1970 and became known as Ghana Secondary Technical School. This was to keep the initials of G.S.T.S.

Interestingly 5 girls have passed through the school as “Old Boys”. They passed through from 1991 to 1993. They were among the first batch of the Senor Secondary School programme. Currently the school runs the General Arts. Science and Technical programme. The school’s motto is in Latin – “Mente et Manu” which means “With mind and hand”.
