The Ghana Secondary Technical School is a science and technology-oriented high school located in Takoradi on the west coast of Ghana. It is the third oldest high school in Ghana â the oldest 'non-missionary' high school. The School was founded on 9 August 1909 in Accra as Accra Technical School and later changed to Government Technical School. It moved to its current site in Takoradi in 1939. In 1953, the name was changed to Government Secondary Technical School, and in 1970, it was given its current name. Former students of the school are known as Giants, and students in the school are called Tescans.
The school was started in 1909 as a pure Technical School and was then sited at the former premises of the Accountant General (the current site of Kinbu Secondary Technical School in Accra). It was founded in response to the growing demand for technical education in the British colonies at that time.
In 1939, the school was moved to Takoradi. The first head was Mr. T. T. Gilbert. The first African head was Mr. J.W.L. Mills, who took up his post in 1958. A sixth-form was introduced in 1961.
The school's name changed from Government Secondary Technical School to Ghana Secondary Technical School in 1970.
For a brief period in the mid-nineteen-seventies students were admitted as part of military training. This started with Intake 15 of the then Military Academy and Training Schools. They underwent a combination of regular academic work with intermittent military training during holidays.
In 2025, the Ghana Secondary Technical School (GSTS) from Takoradi achieved a remarkable feat by eliminating Presbyterian Boysâ Senior High School (PRESEC), Legon from the National Science and Maths Quiz (NSMQ). GSTS triumphed in the quarter-finals with 39 points, narrowly defeating PRESECâÂÂs 38 points and Our Lady of Grace SHSâÂÂs 28 points. They were later edged out by the previous winners, Mfantsipim School.
