The purpose of the Sixth Form in Ysgol Gyfun Gymraeg Llangynwyd is to provide the highest level of education, a wide and varied range of opportunities and the necessary support for every student to achieve their potential and fulfil their ambitions for the future within a Welsh environment. The Sixth Form is a vital part of the life of the school. There is a wide range of academic courses to choose from, especially due to the successful partnership with Ysgol Llanhari.
Years 12 and 13 are open to all students who meet both the academic and personal expectations of the Ysgol Gyfun Gymraeg Llangynwyd Sixth Form. Every student who has achieved 5 grades C or above at GCSE, with at least one of those in a core subject (Welsh, English, Mathematics, Science), will study three level 3 courses (A level/BTEC) and the Skills Challenge Certificate in order to fulfil the requirements of the Welsh Baccalaureate. Every student in the Sixth Form is expected to contribute to the ethos of the school by promoting the use of the Welsh language, as well as being positive role models to the younger pupils.
The school offers a range of valuable extra-curricular opportunities, from sports teams to music ensemble; STEM projects and dramatic performances. In addition, there are opportunities to take part in voluntary activities as part of the Skills Challenge Certificate such as running a club for the younger pupils on a Friday afternoon, as part of the Duke of Edinburgh Award, working with the Urdd as Sports Leaders and Ambassadors as well as with local and international charity organisations. In doing so students develop into well rounded citizens by developing essential skills such as problem solving, working with others and improving their own performance.
The Sixth Form has a dedicated modern and contemporary work space where there are excellent resources. The ICT room has the latest software, and Wi-Fi available for personal digital devices. In addition, the Lolfa offers a comfortable and informal area to study in non-contact periods.
