Principal's Welcome

As we enter the academic year 2023/24 there is a new feel in the air at Castle School - one of enormous energy, excitement and positivity as we look forward to a vibrant and busy school year.

Since relocating in 2020 one of the toughest challenges we have faced has been rebuilding the true ‘sense of Castle School’ with all the wonderful parts that make up our truly inclusive family environment.  Not the easiest task in the post pandemic climate but we are there - Castle School of old is back.  Progress, growth and development are really important but retaining and cherishing our core values is essential.  When developing the idea of Castle School I had a very simple remit - it needed to offer a place where children could be safe, valued and thrive.  In 2009 they were and in 2023 they still are.  We adjust to meet new challenges but our ethos will always remain the same.

At Castle School we recognise and fully understand qualifications are a vital part of what we do and an enormous asset to our learners - our GCSE results are always strong - since opening 15 years ago we have topped the local schools ‘league’ and hope this will continue - we are constantly reviewing our teaching and learning and investing in exciting CPD for our staff team to ensure we maintain standards and keep abreast of educational developments.

What we further understand and fully subscribe to is a commitment to assist our pupils in becoming resilient, confident and kind learners with the self belief and self knowledge to navigate their way through this ever changing and increasingly complex world in which we live.

We are firm believers that learning outside the classroom is golden - it is a core part of our provision - it is what we do - in spades; in the community, on the sports field, in boats, in fields, on ski slopes, at home - in fact at every opportunity.

I am delighted the soul of Castle School is very much still with us.  Please take the time to watch this very short video - made in 2014 by a talented young graphic artist assisted by our pupils and staff.  At the time our home was a pretty run down Victorian school house and a 1960s prefab building but I think you will agree the joy, fun and spirit of our pupils shines through.

We now have a ‘campus’ with three sites offering provision from 2 years to 18 years - with our own cookery school, Activity space and Outdoor School - the school has grown and developed but the core ethos stands:  Learning should be joyous, inspiring and exciting.  At Castle School we are committed to these key components in our provision.

For further information, an informal chat and/or a look around our school please contact us via the website or call 01437 558010.

I wish everyone the very best for a productive, fun and joyful academic year in and out of the classroom.

We're committed to helping our students reach their full potential, both academically and personally, and we believe that our management structure is key to achieving this goal.

The school has maintained a remarkable track record, consistently achieving over 97% A* to C grades at GCSE, surpassing the county average of approximately 65%. Castle School initially started in modest primary premises with only 23 pupils and 6 staff. However, it has since grown to accommodate roughly 200 pupils and employ about 35 staff members.


Three Dedicated Sites

Castle School comprises three distinct sites, including Glenover House, The Early Years Centre, and Sixth Form Centre. The primary location is Glenover House, where our Prep, Middle, and Senior schools are situated. Additionally, the Glenover House campus houses a magnificent space for the pupils to create a school garden and an outdoor school classroom. Moreover, we have a dedicated teaching kitchen at our Early Years Centre, accessible to the entire school as part of their academic curriculum.
