At Sydenham High School we aim to inspire the future generations of creators, independent thinkers and trailblazers, empowering every girl to forge her own path, strive to be her best and excel. Just a short walk from Sydenham Overground station and easily accessible from across South East London, Sydenham High School is an independent day school for girls aged 4 to 18.

Girls at Sydenham High are ambitious and open minded, with the inner strength and self belief necessary to outstrip all expectations. They are also well rounded, intellectually curious, down to earth and happy.

The school’s original Anglo Saxon motto, ‘Nyle ye drede’, means ‘fear nothing’ and underpins all that we do. Sydenham High is selective and diverse, welcoming girls with wide-ranging talents and backgrounds into a close community that is large enough to offer choice and flexibility but compact enough to ensure that no girl is overlooked.

The best way to discover how we do this is to visit us in person and see our school in action at one of our open events:

Senior School Open Morning on Thursday 21 March (9.30-11am) Prep School Open Morning – Tuesday 12 March (9.30-10.30am)

"Meet the Head" Coffee Mornings throughout the year.
