The college was established in 2004 as the Cardiff Centre of Excellence (CCOEX), and was originally intended as a private tutorial centre which met regularly in a local church. By 2008, it had become a private company limited by guarantee and had moved to a residential house on 97 Newport Road. In 2012, it was renamed the Cardiff Sixth Form College, and the college moved to its present site at Trinity Court.^[2]

In 2021, the college revealed plans to redevelop Merchant Place in Bute Place and Cory's Building in Bute Street and a new building at the rear. Both Merchant Place and Cory's Building are Grade II listed buildings and form an L shape.

The college caters for students studying for their A Levels and uses the WJEC exam board for all subjects, but the main emphasis is on providing students with the relevant experiences and skills to enter the university of their choice.^[3] It also offers summer school courses based at its UK campus in Cardiff.^[4][5] The college has also made significant outreach efforts to recruit students from other countries and regions, most notably Botswana, Hong Kong, Malaysia and China.^[6]

In November 2016, the former trustees of the college were the subject of an inquiry by the Charities Commission due to failure to submit their accounts on time. The Charity Commission has identified regulatory concerns about the charity's governance, financial management and significant related party transactions between the charity and some of its former trustees. An interim manager was appointed to oversee the running of the college over the course of the inquiry. South Wales Police were looking into potential fraud at the college by the former trustees.^[14]
