Sunyani Senior High School (SUSEC) is a coeducational second cycle institution in Sunyani in the Bono Region of Ghana.
Sunyani Secondary School popularly known as SUSEC is one of the products of Ghana Education Trust. It was established in 1960 by Ghana's first President Osagyefo Dr. Kwame Nkrumah.[1] [2], the then Prime Minister of Ghana.
The first batch of students 36, in number, comprising 31 Boys and 5 girls were admitted on Friday 30th October, 1960.
On 13th December, 1960, Osagyefo Dr. Kwame Nkrumah inaugurated the school at a colourful ceremony. The school started with only 3 Teachers and 9 Non-Teaching Staff.
Sunyani Secondary School started as a co-educational Institution but after a short time, people in high places decided to make it a Boys’ school. As a result, the few girls in the school were sent to Yaa Asantewaa Girls’ School. Fortunately, the decision was rescinded and the following year, girls were admitted again to the school.
The first Headmaster of the school was the late Mr. P.D. Quartey, a bold Sportsman and adventurer who dared the unknown to come from Accra to Sunyani to start a big programme. He and his staff did a yeoman’s work to lay a solid foundation for great institution to emerge in Brong Ahafo Region.
The school's emblem, an Elephant, was selected because the name Sunyani is a distorted variant of the name "Ason Dwaee," signifying the location where the legendary hunter and warrior Nana Boahen Korkor, the creator of the Sunyani traditional territory, killed and skinned elephants.
The famous leader Osagyefo Dr. Nkrumah said in Latin that "A man was born not for himself alone but for his country," which inspired the motto "Me man nti enye me nti," which was originally used by the first Headmaster, Mr. P. D. Quartey, of blessed memory.
By methodically building on the strong foundation that previous heroes set, the current administration has turned Sunyani Secondary School into a vibrant, resilient, and strong academic paradise for students who aspire to succeed in life.
Over the years, the school has grown tremendously and remarkably. The number of non-teaching employees has increased from nine (9) to one hundred and five (105), while the number of teaching employees has increased from four (4) to one hundred and ninety-eight (198). Four thousand four hundred and thirty-seven (4437) students now make up the original student body of 36.
