A leading independent day school for boys & girls age 3-18

Choir School to Cardiff Metropolitan Cathedral

"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.


A welcome from the Headmaster

Thank you all for the very positive responses to my new post. I have accumulated 30 years of teaching experience at St John's as well holding the positions of Examinations officer and Assistant Head. St John's is an extraordinary community, within which I feel privileged to belong. The family spirit which is engendered at the school held out its arms to my own daughters who were warmly welcomed and educated up to A Level. Be assured, the core values and Catholic ethos of the school will continue and prosper under my guidance and that of my senior staff. We shall be moving forward with our new initiatives both academic and co-curricular.

St John's College prides itself on its outstanding academic results and exemplary pastoral care and we are immensely proud of all our achievements and progress which has now been recognised in our most recent ESTYN inspection report where we achieved Excellent  Standards: "The standards achieved by pupils across the school are extremely high and throughout the school pupils are confident and articulate learners". We are indebted to all our dedicated staff, hard-working pupils and supportive parents.

Mr Shaun Moody - Headmaster
