Welcome

MBL 202324Thank 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.

Executive Headteacher

of school"
