We are not your typical school. Not only are we Northwest London’s leading co-educational, all-through 3 to 18, independent school but we also are part of something much bigger. John Lyon School sits within John Lyon’s Foundation and is one of the key constituents of the Harrow Family of Schools.
The Harrow Family of Schools comprises:
John Lyon School
- John Lyon School (www.johnlyon.org)
- John Lyon School (Prep) (www.johnlyon.org/prep-school)
- John Lyon School Alumni – Lyonian Association (https://lyonian-association.org/)
Harrow School
- Harrow School (harrowschool.org.uk)
Harrow International Schools
- Harrow-branded schools operating in 10 campus locations in China, Hong Kong, Japan and Thailand by Harrow’s founding schools-franchise partner, Asia International School Limited (aislharrow.com);
- Harrow International School Bengaluru, India (www.harrowbengaluru.in), the first of five planned Amity Harrow Schools, including one in New York, USA; and
- Harrow School Online, which is owned and operated by Pearson (harrowschoolonline.org).
In total, the Harrow Family educates over 9,000 pupils each year. All schools in the Harrow Family that are eligible for inspection were most recently marked “excellent” or “outstanding” in all areas. On average, 48% of the Harrow Family of School’s Year 13 leavers in 2022 had places at the top 100 universities in the QS World University Rankings, with 44% of John Lyon School pupils going on to study at Russell Group universities.
The unique set up of the Harrow Family of Schools means that John Lyon pupils benefit from these close links and regularly take part in pan-Family events, including an annual Fifth Form Conference, assemblies and lessons streamed with partner schools, creative-writing anthology and a STEAM magazine. In addition, staff often have the opportunity to collaborate with colleagues all over the world in order to develop best practice and exchange ideas and resources.
We are proud to be part of this diverse and pioneering global educational community.
We provide a wide range of sporting activities and opportunities for all pupils.
At our Prep School we concur with educational theorists who emphasise the importance of the creative mind and ‘emotional intelligence’ and ‘wellbeing’ – the need to develop the whole personality and our pupil’s imaginations especially. Drama has the power to liberate the mind.
We encourage our pupils to become healthy, independent and responsible members of society. 
At our Prep School, Computing covers the use of electronic technology in all its forms, including computers and other communication devices.
• What is religion?
Art is an integral part of our Prep School’s curriculum, providing our pupils with a unique means of expressing their ideas by allowing them to explore new thoughts and give life to their creative minds.
History is taught throughout the School and pupils are encouraged to find out about events and peoples.
Planet Earth is our only home. It is an mind-blowing, diverse and constantly changing place of awesome beauty and power. 
French is the language of our nearest neighbours, probably the easiest foreign language for English speakers to learn and, after English, one of the most widely-learned languages worldwide.
The core of every science lesson at our Prep School is about developing every pupil’s curiosity in the world around them. 
Mathematics is a key subject for children of all ages at our Prep School.
English is taught using lively and creative methods through a variety of texts and resources incorporating ICT from Pre-Prep onwards.
