About Us

Castle school was started by the Principal, Mrs Harriet Harrison, in September 2009. The aim was to establish a school with an ethos of educational success alongside individual support and guidance and with an emphasis on equipping pupils with skills for life.

We pride ourselves in meeting the needs of our pupils, from the gifted and talented to those who experience learning challenges, by tailoring education to the individual through:

  • Commitment to small class sizes.
  • Stress free learning.
  • Encouraging high expectations.
  • Investing in the complete child.
  • Zero tolerance to bullying and any form of disruption.
  • Developing Life Skills.
  • Building confidence and self esteem.
  • A diverse range of trips and activities enhancing your child’s all round development.
  • The unique environment of Castle School supporting the social and emotional development of all pupils.


At Key Stage 3, pupils study English, Mathematics, Science, History, Geography, IT, Art, Latin, French, Spanish and Physical Education.

At GCSE and A level a wider variety of subjects are offered including the above and Astronomy, Psychology, three Sciences, Computer Programming and four languages – French, Latin, Spanish and Welsh.
