Welcome to Isleworth and Syon School for Boys

“Pupils, and students in the sixth form, study an ambitious and broad curriculum that prepares them well for the next stage of their education.” – OfstedIsleworth & Syon has an extremely successful mixed Sixth Form which welcomes applications from all young people. Our primary aim is to ensure that all students experience an academic education of the highest standard, and the school offers a highly supportive environment for students to continue their post-sixteen studies. We take both internal applicants (from our Year 11) and external applicants (from other schools).Isleworth & Syon School were very proud of its Year 13 cohort this summer as they collected their results. These top grades serve as a stepping stone towards their dream next steps as they complete their journey with the school. Students will be attending some of the best institutions in the country; you can see our full list of university leavers. These results were a testimony to the school’s continued desire to be ‘outstanding in every respect’.In the Sixth Form, our expectations are high, with senior students expected to operate as role models for students in the lower school. This is reflected in the Sixth Form appearance policy.Please click on the tabs for more information about what our Sixth Form has to offer.
