Vision & Values

About
Clayesmore

125 Glorious Years

A Rich History and a Bright Future

Lex Devine, our Founder

Clayesmore was founded in 1896, by Lex Devine. A man ahead of his time in terms of his vision for education. His guiding principle was to offer ‘an all-round education’; he understood the importance of a traditional academic education but he also recognised that, without a strong foundation of values and attitudes, it was nothing. That ethos remains at the heart of a Clayesmore education today.

An inspiring place to live and learn

Clayesmore settled in Iwerne Minster in the summer term of 1933, having previously had homes in Pangbourne, Berkshire and Winchester, Hampshire. In 1974, it was joined by Clayesmore Preparatory School, originally Charlton Marshall School, which had been founded in 1929 by R.A.L. Everett. In the following year the school became co-educational.

Adventurous Spirit

In Clayesmore's 125 year history, the spirit of adventure and pursuit of happiness in every aspect of life, including academics has always been clear. We encourage every pupil to 'have a go' with the aim that they uncover their passion and fulfil their ambitions.

Leadership and Service

Service and leadership are key principles of a Clayesmore education, and always have been. The Sixth Form programme, ACE (action, community, environment) provides opportunities for all pupils to spend time in the local community supporting the elderly, young children or the environment with an aim to dvelop a culture of 'giving back' and a sense of responsibility for the wider world.

Embracing the Outdoors

We are blessed to be located in the most glorious Dorset countryside, surrounded by stunning coastline. A Clayesmore education has always embraced the outdoors and the benefits that can bring. Every year, Pupils take part in the Duke of Edinburgh Award programme as well as enjoying country sports, watersports, equestrian activities, climbing, walking and much more.

The Future of LEX

In our 125th year, we proudly introduce LEX, a bold and ambitious weekend programme of trips, experiences and events. LEX is the embodiment of our founder's original principle, enabling pupils to seize fresh opportunities, develop new skills and provide them with transformative experiences and skills to draw upon forever.
