Headteacher’s Welcome

Aidan Timmons, Headteacher

Welcome to Steyning Grammar School (SGS), a unique and exciting school that combines the credibility of a long history with an ambition to be innovative and a willingness to forge its own way.  A school that is built on the firm foundations of high expectations for all with a creative and personalised curriculum that will extend learning both in the classroom and through a wide range of enriching experiences and environments.   

Our students are at the heart of all we aspire to and achieve. We are committed to and experienced in developing confident, ambitious and skilled young people who will relish their role in making a positive difference to their communities; whether local, national or global. SGS students are well equipped for any challenge or opportunity.

Our positive and collaborative culture is underpinned by the belief that all members of our school have the potential for excellence. We are committed to raising aspiration and dedicated to supporting all students develop the confidence, self-belief and well-being vital for success.  Our Christian Ethos of kindness and the celebration of diversity, Bohunt Education Trust’s values of Enjoy Respect Achieve and our own unique character education  combine to embed a culture that informs the decisions and actions of everybody in the community meaning everyone in our SGS family will be able to achieve and flourish. 

We are a complex organisation with multiple sites, a state boarding house and students ranging from ages 11-18.  The size and scale of the school is a strength, allowing there to be smaller schools within the school, ensuring everyone can be known as an individual with their needs understood and met.  The breadth of experience of our exceptional staff, all of whom believe passionately in the possibilities of our students, along with support from home gives us powerful tools to get the best out of each and every one of our students during their educational journey at SGS. 

I studied Fine Art at Central St Martins before specialising in Sculpture for my degree at the Kent Institute of Art & Design. I completed a PGCE in Art & Design at Brighton University before taking up my first teaching post at Peacehaven Community school where I stayed for 8 years, becoming heavily involved in curriculum development and staff training. During this period I completed a Masters in Education from the University of Sussex before moving to the Peterfield School in Hampshire. Whilst at The Petersfield School I held the positions of Assistant Head, Deputy Head before becoming Head of School in 2019. After thirteen years at TPS in which time the school has now been recognised as Outstanding by Ofsted, I was delighted to join Steyning Grammar School as Head of School in 2023 and now, Headteacher of Steyning Grammar School as of February 2025.

What I have loved about my three years so far at SGS are the brilliant resources and facilities. For example, I really enjoy the library at shooting field, which has a range of books and ebooks (which I can read on my iPad at home and at school).
