School Houses

Every pupil belongs to one of the school’s four Houses. These are Abbeygate, Balkernegate, Headgate and Scheregate – named after the gates of Roman Colchester. Throughout the year, there are challenges of all kinds. This includes cake sales and quizzes and charity fundraisers, which offer opportunities for pupils to work together across the year groups and are entered into with great enthusiasm! House Cups are presented at the end of each year.

Positions of responsibility

From helping in the library to perhaps becoming a Lower or Senior School Head Girl, Games Captain, House Official or Prefect, there are many opportunities for pupils to develop their leadership skills. Positions of responsibility also enable the girls to make an active contribution to the school community. School Councils at both the Lower School and Senior School give pupils a voice and their input into school life is valued. Many posts of responsibility are applied for and democratically elected.


We know wellbeing matters and is critical to achieving. Our girls are not only confident and capable, but also kind and responsible. The wellbeing of every individual, pupil and staff member is of paramount importance at St Mary’s. It informs all that goes on at the school. In such a supportive, caring atmosphere, girls learn to be successful. At the same time, it develops a sense of integrity and a strong empathy for those around them.

Mental health

At St Mary’s mental health and wellbeing is at the forefront of our agenda. We are always looking for new ways to support our students and parents. As a result of this we have recently invested access to the Teen Tips Wellbeing Hub, a website for students, parents and teachers. It provides a wealth of resources and information, including webinars and podcasts.

Girls on Board

St Mary’s is proud to be a ‘Girls on Board’ school. That means that when our girls experience some turbulence in their friendships – which is inevitable from time to time – we take an empathy-based approach to supporting them. The approach is described in more detail on the website and key members of the St Mary’s staff are fully trained. Girls on Board has won many national prizes since its creation in 2017. It has been adopted by over a thousand schools world wide. It has proved to be a very effective way of creating lasting harmony amongst girls in school and St Mary’s is committed to its use.

Peer support

The Year 6 girls complete the peer-led Head Smart Wellbeing Ambassador programme. This initiative highlights to the girls how to help others think about their own mental health and the practical things they can do to promote positive wellbeing.

All Senior School pupils take on a pastoral role as ‘Buddy’ to a girl in the year below, helping her to settle into the school and offering support during her time at St Mary’s. In this way ‘Buddy Families’ are formed and there are fun social events for Buddies throughout the year. Selected girls in Year 11 are trained as ‘Listeners’, peer mentors who lend an ear to pupils with minor problems to discuss.


St Mary’s has recently been awarded Anti-bullying Ambassador Status from The Diana Award. The programme’s trainers work with students aged 11-15 to change the attitude surrounding bullying and has a strong peer-to-peer focus, with trainers giving young people the skills and confidence to become Anti-Bullying Ambassadors within their schools.
