In 1988 the school was founded as St Piran's Preparatory School by Mr Jimmy Reid and his wife. The school was named after the patron Saint of Cornwall and the school continues to celebrate St. Piran's Day annually.  

The school continued as a family run establishment, under the new joint Headship of Mr and Mrs David Jones, until their retirement and the sale of the school to The London School of Commerce, a large multi-national education provider in 2003.   

Mr Deryck Wilson was appointed Headteacher and began the development of the school. While St Piran's began as a primary school Mr Wilson began the process of extending the school to provide secondary education, initially to the end of Year 8.   

Mrs Carol de Labat became Headteacher and the school further developed and extended to Year 11 and GCSE provision. In 2013 the school celebrated its 25th anniversary providing high quality individual education.

In 2022 the Headship passed to the then Assistant Headteacher Miss Louise Adams on an interim basis and she became the permanent Headteacher in September 2023. 

In November 2024 the group that the School belongs to underwent a restructuring process and The Cornwall Independent School (UK) Ltd was formed. Day-to-day school life, our academic programme, extracurricular activities and student care will remain unchanged.

The quality of education and pastoral care that your child currently receives will always remain our top priority. We believe the values, ethos, and supportive environment that make our school a unique place for learning will be enhanced by the opportunities this new company will bring. It has always been our aim to make quality education affordable to parents and this will continue to be a priority.
