We also provide every opportunity for our pupils to participate in Cardiff Games which provides pupils with a wide range of opportunities to participate in sport. Many pupils regularly participate in community events such as kwik cricket festivals, sporting matches, athletic events. Several pupils represent Cardiff County, Wales or Britain at sporting events such as swimming, gymnastics, cricket, football, netball and cycling. Several pupils represent the school in Cardiff and the Vale of Glamorgan Orchestra and ensembles.
