Welcome

MBL 2026Thank you for visiting our website, whether you are prospective parent; studet; member of staff; or simply to browse. It is my pleasure to introduce
The Bishop of Llandaff CiW High School to you.

We are an 11-18 co-educational Anglican school, serving the Christian and non-Christian communities within the city and surrounding areas including The Vale of Glamorgan, Caerphilly, Rhondda Cynon Taf and Bridgend. 

Our aim is to provide all our students with the very best start in life by offering them an outstanding secondary education. We seek to achieve this by ensuring each child in our care

  • reaches their full potential academically;
  • develops a broad set of skills that enables them to be successful in our ever-changing world; and
  • understands a sense of morality, guided by the gospel values of love; acceptance; responsibility; and forgiveness.

These aims are delivered through a commitment to providing the highest quality learning experiences, a strong pastoral system and an extensive range of sporting, cultural, physical and extra-curricular activities.

The Bishop of Llandaff is a high performing school. Our public examination outcomes consistently places us amongst the very best in the UK, both in terms of actual attainment and student progress. We are very proud that our students consistently achieve outstanding GCSE and A level results, with many leaving us to continue their studies at university throughout the country (and some abroad on full scholarships). However, more importantly, we are proud that each of our students secure a progression route to the next stage of their lives, regardless of their chosen pathway.

Should you visit, you will see that our students (on the whole!) are happy, hard-working, and incredibly positive about their experience at school. They are a genuine asset to our community and visitors regularly comment on how friendly, polite and articulate they are. Our students want to receive the best possible experiences at school, and to become successful. In addition to our wonderful students, we have some of the finest teachers and support staff in the country who help inspire, motivate and challenge our students to become the ‘best versions of themselves’.

It is my belief that children have 'one chance' at education and they deserve the very best! At The Bishop of Llandaff, we see it as our role to ensure we provide them with this. We set the highest expectations of and for our students, and we will leave 'no stone unturned' in our pursuit of excellence in all areas of our work. We are committed to continuous school improvement and place great importance in working together in partnership with families so that each student receives the best possible educational experience.

Educating children is a great responsibility and an immense privilege. If you are a parent of a student already at the school, thank you for entrusting us with that job! If you are considering sending your child to The Bishop of Llandaff or would like to find out more, then do get in touch.

Dominic Bailey (Year 13)

It is with deepest regret that we share the news that Dominic Bailey, one of our Year 13 students, tragically died in a road traffic accident on Saturday 6th June 2026. Dominic was well-known across all year groups. He was a large personality within our school and had exciting ambitions to travel upon completing his A level studies. He will be sorely missed by everyone at The Bishop of Llandaff and, in particular, his close circle of friends. We give thanks for Dominic's life, for the joy he brought to others, and for memories that will remain in our hearts. The immediate thoughts and prayers of the whole school community are with Dominic's family as they begin to come to terms with this profound loss. When communicating the news with students and staff, the following prayer was shared  Heavenly Father, We commend the soul of Dominic, one of our school family, who has left us to come into your hands. We thank you for placing him in our life here on earth. We glorify Your name for giving the time we had with Dominic. Fill our hearts with courage and help us to accept that he is now with you. Let this knowledge of Dominic joining you in paradise, where perpetual light will shine on him, be our source of comfort and strength. In Jesus’ name, we pray. Amen. The school will provide support to students and staff during this time of grief, and will continue to come together as a community to remember and honour Dominic's life.  I ask that you respect the privacy of the family and school at this deeply challenging time.
