The school was established in 1806 by Mary, Countess of Harcourt of St. Leonard's Estate, at her own expense and voluntary contributions, in two converted cottages at Clewer Green. The school was a Charity School, set up to teach the children of the poor who lived in the parish. Upon her death, the deeds were donated to the Diocese of Oxford, although the descendants of the Countess still maintain links with the school through the Harcourt Trust.

Over the years, the original building has been modified and extended to keep up with increasing numbers and statutory changes in educational provision.  We are very proud to have a dedicated ICT suite, a music and drama studio and a separate hall for PE and assemblies; which is a hive of activity from 7.45 to 5.30pm with our in-house breakfast and after-school clubs.  The school facilities are also used for community events throughout the year and available for private hire outside of school hours.

Foundation Stage has a dedicated outdoor area, which has very recently been completely refurbished.

In addition, to the rear of the school, we have a large playground, field, eco-garden and pond.  We have a very active PTA, The Friends of Clewer Green, who have supported us with funding new playground equipment.  We have a play tower, monkey bars, trim trail and climbing wall for children to use at break times.  The school hosts a range of PTA family events such as bunny bingo, a school disco and Summer Fair which you and your family can enjoy.
