There will also be an opportunity for every pupil to enjoy Drama lessons as well as other aspects of education which contribute to the student's personal and social development. Information Technology Key Skills are developed through specific lessons on every pupil’s timetable and across the curriculum.
The school places great emphasis on the development of the latest teaching and learning techniques. We encourage teaching methodology that offers our pupils the opportunity to work together, problem solve, work as team members, research and formulate theories and develop opinions and points of view. Such methods develop pupils’ self-respect and self-worth as well as making them independent learners. The development of pupils’ Essential Skills are enhanced and developed in this way.
The school is committed to giving every pupil the opportunity to achieve qualifications by sitting public examinations. Consequently, each pupil has a recognised qualification when he/she leaves Ysgol Gyfun Llanhari. The vast majority of the courses offered at Key Stage 4 lead to a General Certificate of Secondary Education (G.C.S.E.) and it is also possible to gain qualifications in vocational courses. The courses offered to years 12 and 13 lead to various recognised qualifications.
