Director's Welcome

Welcome to Sedbergh International Summer School!

For over a decade, Sedbergh International Summer School has been attracting international pupils from around the globe.

Accredited by the British Council, we provide a unique summer experience for pupils between the ages of 8 and 16, enabling them to improve their language skills whilst making connections with other pupils from around the world.

We were delighted to welcome pupils back to Sedbergh in 2022. It was a joy to watch friendships develop as our pupils navigated their way through their chosen programmes, communicating, collaborating and developing in confidence as they made the most of the vast array of opportunities available to them.

Our mission is to ensure each pupil is encouraged to realise their full potential, exploring the limits of their ability whilst learning to thrive outside their own comfort zone. Our dedicated team are committed to providing our pupils with a rich educational experience within an environment that encourages them to flourish, develop existing talents, discover new passions and make life-long friendships in a safe, supportive environment.

Due to the increased demand for places on our Summer School we are excited to announce that we will be hosting pupils exclusively at the senior school site for the first three weeks of the ISS 2023 programme. Thereafter, we will continue to operate across both the senior and prep school sites as before.

As part of the Sedbergh School family, we are proud to boast a reputation that reflects over 500 years of tradition and heritage. We hope that you enjoy learning more about our Summer School
