About Isleworth and Syon School for Boys
Isleworth and Syon School for Boys sits within the Hounslow local authority, where it ranks 18th out of 19 secondary schools on Progress 8, placing it in the bottom tier of the borough. For context, the top-performing peers in the area are St Mark's Catholic School, Gunnersbury Catholic School, and Reach Academy Feltham, all of which achieve significantly higher Progress 8 scores. The school is a boys-only state secondary with a mixed sixth form, and it operates as a non-faith school with no religious character. It is heavily oversubscribed: for 2025/26 entry, there were 285 applications for 100 places, with 55 first-preference offers made. That gives an oversubscription ratio of 2.85, suggesting strong local demand despite the modest ranking. The nearest school rated Outstanding by Ofsted is Nishkam School West London, just 0.8 km away, which may be a factor for families weighing options within the same catchment.
