Glenthorne High School is a thriving 11-19 mixed comprehensive Academy with 1704 pupils, of whom 350 are in the 6th Form.

We are a heavily oversubscribed, highly successful school with a long and rich history in the local community. The school was founded on the Glastonbury Road site in 1933. It moved to the Sutton Common Road site in 1958. At this time, it was called Sutton Common County Secondary Girls’ School; a small girls’ school for less than 400 pupils. It changed its name to Glenthorne in 1982 and it wasn’t until 1993 that it became co-educational. In 2018, we celebrated our Diamond Jubilee on the Sutton Common Road site.

I joined the school back in September 2000 and is now my pleasure and a privilege to lead the school on the next chapter of its journey. Glenthorne is a unique school of extraordinary staff and pupils and enjoys exceptional support from parents and the local community. We are proud of our history, our success and achievements and our reputation for high standards and high expectations and proud of our contribution to the local community. ​​​​​​​

Yours faithfully,

Our Ethos
“Achievement for All” is our motto and guiding principle. We have established an achievement culture in which every single pupil is encouraged to succeed. We aim to develop each individual’s talent and release each individual’s unique potential. We are an inclusive school and strive to meet the needs of all pupils across the ability spectrum.

Our Values
We believe in traditional values and high expectations. We promote a structured learning environment with an emphasis on the importance of homework. We expect high standards of behaviour, excellent attendance and positive attitudes. We believe in equality, diversity and inclusion. We are a school that actively combats racism and discrimination of all types and we value all our pupils equally, whatever their ability, background or ethnicity. We have a traditional approach to discipline with zero tolerance of disruption and we encourage courtesy, respect, consideration for others, punctuality and pride in the uniform of the school. We encourage all our pupils to contribute to the local community and to remember those less fortunate and we have a rich tradition of charity fundraising at the school.

Our Rewards
We provide a happy, safe, secure school and a caring environment for all pupils. We believe you get the best out of children through praise, encouragement and reward. We reward for effort and participation to motivate and inspire: achievement points, vouchers, reward trips for excellent behaviour, attitude and organisation, and a very special Awards Evening called "Glenthorne Celebrates" every year in June.  

Our Extra-Curricular Opportunities
We encourage all pupils to participate in our comprehensive extra-curricular programme, including a huge range of lunchtime and after-school clubs, cultural and educational visits and residential trips at home and abroad. Our sports teams have enjoyed great success and our performances and productions have a reputation for excellence. We run the Duke of Edinburgh Award scheme for pupils in key stage 4 and 5.​​​​​​​
