The school's first headmaster was David W. Howells, who was previously headmaster at Quakers' Yard Grammar School. One of its longest serving teachers was Howard Davies, who for a time taught maths but eventually finished out his career at the school as a deputy headmaster. The current headmaster is Mr Mike Johns. The deputy headmaster is Mr Clifford Smith.
The school is a strong supporter of the Sixth Form. Past years have seen calls to abolish the sixth form in Afon Tâf as well as others in Merthyr Tydfil in order to centre A-Level education in the county borough at a Sixth Form College.
