We believe that girls are remarkable and have different educational needs. With us, your daughter will be inspired, build resilience, advance academically, learn what interests her and grow. We understand that girls’ wellbeing matters and is critical to achieving. Girls at St Mary’s are not only self-confident and capable, but also kind and considerate.

We know that as parents, you want the world for your daughter – and so do we. And when she leaves us she’ll be empowered to rise to the challenges and the opportunities the world presents.

A strong academic education

We are very proud of our pupils’ success in their GCSE examinations. This year, 55% of GCSEs were 7-9 or equivalent (comparable to grades A*-A), more than double the national average. More than half of the results for the core subjects of Maths, English and Science were graded 9-7. An exceptional 100% of results for Latin, Fashion & Textiles and Hospitality & Catering were graded 9-7 or equivalent.

St Mary’s Lower School is the 12th highest performing Prep School in England, as ranked by the Sunday Times. This year, eight pupils passed their 11+, making us the biggest feeder to Colchester County High School for Girls. Our pupils also achieve outstanding SATs results. In 2025, 90% achieved the higher standard in Reading, almost three times the national average of 33%, 74% achieved the higher standard for Maths, almost three times the national average of 26%, 58% achieved the higher standard for Grammar, Punctuation and Spelling, almost double the national average of 30%, and 42% achieved greater depth for Writing, over three times the national average of 13%.

We’re able to achieve such success by tailoring the education to suit the needs of each individual in our small classes, and by giving the pupils the encouragement and support they need to aim high.
