"St John’s College, Cardiff is used to the celestial as choir school to Cardiff Metropolitan Cathedral. However, this year it was not just the school’s music that was out of this world. Anyone obtaining a C grade on A-level results day in August will have felt a little lonely, as 98.1% of all outcomes secured A*, A or B grades, putting Eton, Westminster, St Paul’s et al into the shade. It is a remarkable achievement for the 525-pupil Catholic day school, in Old St Mellons."

The Sunday Times Parent Power - December 2017

This achievement is based on the school’s outstanding academic results and our commitment to an exciting programme of co-curricular activities. Emphasis on an ethos that promotes the development of the whole child, in preparation for University and careers after school, has been critical in attaining this accolade.

This prestigious award follows a record-breaking summer of A Level results when the annual league table published in The Times newspaper put us in 3rd position behind two selective Sixth Form colleges, thus confirming our status as the number one secondary school in the UK overall.

Welcome from the Headmaster
Croeso cynnes wrth y Prifathro

Thank you very much for visiting our website. St John's College prides itself on its outstanding academic results and exemplary pastoral care, but it is the extraordinary sense of community of which we are most proud. Our highly skilled and experienced staff inspire children of all ages, from Nursery to Sixth Form, to achieve their very best, in every area of the curriculum and our extensive range of extra-curricular activities. Pupils respond warmly to this dedicated focus on teaching and learning, developing intellectually, morally, spiritually, aesthetically and physically. Most of all St John's students delight in forming friendships for life, with teachers and pupil alike, underpinned by the values of the Gospel.

Academic work, playing and competing in sport, making music of the highest quality, participating in drama and debating and many other facets of growing in knowledge and understanding are given due importance.

Our heritage of Catholic Christianity calls us to hold the highest values of faith, hope and love for one another. We hope that you will enjoy learning more about this young and evolving school, which has already achieved an enviable reputation both in Wales and amongst the top independent schools in England. Our aim is to create the best possible education for our girls and boys as they become young women and young men, embracing all that life has to offer with passion, commitment, competence and integrity.

Mr Gareth Lloyd - Headmaster
