The buildings in Takoradi were completed in 1939 at the cost of £37,000. The site, was larger by far than the former, the new site being on a 120-hectare ground. Accordingly, packing started immediately from May 1939 and equipment from Accra was transferred to Takoradi during the month of June, July and August by road. The school re-opened in Takoradi on the 21st of September, 1939 under the headship of Mr. T. T. Gilbert. Here its unique character became evident as students from other West Africa countries came to do courses in the school. In 1940 students came from Nigeria and the Republic of Benin (then Dahomey) and in 1941 others came from Sierra Leone. Clearly, grammar schools were present all over West Africa but not Technical Schools.

Just when the school was settling down in Takoradi the World War II was declared and the school had to move house again as its premises were required for the use of the Royal Air Force. In August, 1940 the school moved to the Elmina Castle and the Royal Air Force occupied its buildings. (Today a miniature nose of an aeroplane hangs at the entrance of the main classroom block to commemorate the occupation by the Royal Air Force). The castle was woefully unsuitable for a school and a few alterations were required before it could house a school. Equipment had again to be transferred and this was done in November and December and the school re-opened in January 1941. Fifty (50) of the old students returned.

Then another setback was recorded for after a mere sixteen-month period the castle was also required for the training of service tradesmen, the technical branch of the military force. This time the school was closed altogether or rather was absorbed by the technical branch of the military force, for all the staff and most of the pupils served with the forces until the end of hostilities. The Royal Air Force which occupied the school's buildings in Takoradi moved out in October 1945 giving way for the return of Government Technical School under the headship of Major T.C. Watkins, designated Acting Principal. A few of the former staff were brought back and the school started assuming shape and growing again, though rather relatively slowly, for in 1950 there were 110 students compared to 80, recorded as early as 1928.

THE MODERN ERA

Calling the period from 1953 the modern era is not making to subjective an assertion for the year 1953 saw the beginnings of drastic revision which was characterised by the introduction of a Secondary Curriculum. The school then became Government Secondary Technical School. A five-year course was begun leading to the School Certificate. The pre-1953 curriculum comprised Engineering and Construction with English, Mathematics and Science as background subjects.

From 1953 there was an expansion to include academic subjects like Physics, Chemistry, Elementary and Additional Mathematics, Geography and French. Religious Knowledge, Music and History also came later though for a considerable length of time they were not offered for the school certificate examinations. They were brought in to avert a situation of narrow-mindedness on the part of the products. Government Secondary Technical School had its first African Headmaster, Mr. J.V.L. Mills (who took over from the last white head, Mr. F.E. Joselin) in August 1958. Sixth-form education began in 1961.

Another landmark is the story of the military's involvement in the school. On 3rd November 1965 the late Dr. Kwame Nkrumah, first President of the Republic of Ghana. Announced that Government Secondary Technical School would be adopted and turned into an Air Force Training College.

"Students in the Government Secondary Technical School will be given such opportunities as are appropriate and suitable to make them potential candidate to the Air Force and even for our Civil Aviation," he said. This pronouncement was not immediately followed by any action until the early 1970s when Air Marshall M. A. Otu (formerly Lt. General) and Senior Officers of the Military Division of Ministry of Defense visited the school on 23rd April, 1971 to clarify the intention of the Army involvement in the school.

In the 1972-73 academic year a batch of students were admitted to do a two-year sixth-form course. It was short-lived for no others came.

The academic year 1970-71 recorded another change of the name of the School. From Government Secondary Technical School it became Ghana Secondary Technical School (to maintain G.S.T.S.) when the school ceased to be a completely Government Institution.

The course of the school's history in the 1970s seemed to suggest that everything had fallen in place. The curricula of the school appeared to have undergone all the relevant changes and had stabilised. The school was doing well in sports, always taking the first position in athletics and rubbing shoulder with other schools in hockey, football, basketball and the rest. There were a number of clubs and societies to take care of both the social and academic life of the students. The upward surge in the reputation of the school brought other problems in its wake. The chief of these was the pressure on the school for admission and consequently on the facilities of the school.

Many parents sought admission for their wards without considering whether their children could read the science and technical course. The then authorities of the school gave in to pragmatism and created class for arts. Students who realised they could not read science were given the opportunity to read arts to the ordinary level examination. For a while the school carried on successfully until it became evident that the authorities had bitten more than they could chew in allowing arts to be read to the examination level. The intense pressure on the time-table was an unhealthy one. In 1985, therefore, a bold decision was taken to drop the arts course and this was done with the last batch of full arts students passing out in 1986.

With the introduction of the Senior Secondary School system the authorities realised they could not run away from the maxim, "Variety is the sauce of life." An arts course had to be adopted.
