In our latest full Inspection, we were rated ‘Excellent’ in all categories, including boarding, with no recommendations for improvement in either the Senior School or Sixth Form.

This exceptional result was quickly followed by the publication of the Denominational (Section 48) Inspection, which rated us ‘Outstanding’ in all areas.

Educating girls

As a girls’ school, we understand the needs of girls better than anyone and are uniquely placed to respond to these needs. At St Mary's success comes as much from confidence as from learning.

Our girls choose subjects they enjoy most, free from the pressure of gender stereotypes. Combined with our academically rigorous environment, this enables our students to excel across the board -  achieving excellent examination results and gaining important life skills: an instinct to achieve, the ability to lead and independence.

Our history and ethos

Our school has a strong Christian ethos, built on a Catholic foundation based on the radical vision of Mary Ward about the place of women in society 400 years ago.

We have remained true to our Catholic foundation and, while we welcome girls from all denominations and faiths, a strong Christian framework firmly underpins our school, helping to build and protect the spiritual well-being of each individual student.

We believe in respecting and caring for the individual – others as well as ourselves, both in school and in the wider community.

Our teaching staff

Our highly qualified teaching staff are passionate about their subjects, with many having studied at Oxford or Cambridge university.

They continually explore effective and beneficial ways of teaching and learning, while offering outstanding pastoral care. Our teacher to student ratio is 10:1.

An international outlook

We embrace globalisation, opening our doors to students from different countries and cultures. Reflecting the cosmopolitan community of Cambridge, 20% of St Mary's girls join us from overseas, from over 20 countries worldwide.

We have a truly diverse and cosmopolitan student body from Reception right through to our Sixth Form, adding to our warm and welcoming school environment.
