About The Green School for Boys

The Green School for Boys sits within Hounslow’s secondary landscape as a Church of England state school for boys aged 11 to 18, but it faces stiff competition from higher-ranked peers. In the local authority, it ranks 16th out of 19 schools of the same type, placing it in the bottom quarter by Progress 8 score. The top three performers in Hounslow are St Mark's Catholic School, Gunnersbury Catholic School, and Reach Academy Feltham, all of which post significantly stronger progress scores. The nearest school rated Outstanding by Ofsted is Nishkam School West London, just 1.4 kilometres away. The Green School itself holds a Good rating from its most recent graded inspection in 2020, and an ungraded visit in April 2025 confirmed that standards are being maintained. Its headteacher is Heidi Swidenbank, and the school operates with a capacity of 1,260 but currently has only 772 pupils on roll, suggesting room for growth.

Academically, the school’s Progress 8 score of 0.2 is rated as Average nationally, but it falls below the Hounslow local authority average of 0.44. That means pupils here make slightly less progress than the typical student across the borough. The Attainment 8 score sits at 48.9, and 67.5% of pupils achieved a grade 4 or above in English and maths, dropping to 53.8% at the stronger grade 5 threshold. The EBacc average point score is 4.32, with 37.6% of pupils entering the EBacc combination of subjects. In the sixth form, results are more mixed: the value-added score is -0.22, rated Below average, and the average points per entry is 30.2, equivalent to a grade C. Only 7.7% of A-level entries achieved grades AAB or higher. The school’s Ofsted breakdown shows personal development was rated Outstanding, while quality of education, behaviour and attitudes, and leadership and management were all judged Good.

The school is oversubscribed for 2025/26 entry, with 294 applications for 106 places and 55 first-preference offers, giving a ratio of 2.77 applicants per place. Facilities include a swimming pool, theatre, chapel, sixth form centre, and dedicated art studios and science labs. Sports on offer include hockey, tennis, badminton, and gymnastics, while clubs range from Model UN and Young Enterprise to gardening and eco club. The school provides support for a wide range of SEND needs, including autistic spectrum disorder, speech and language difficulties, and hearing or visual impairments. Parent View responses from 45 parents show 71% would recommend the school, though opinions are mixed on how well concerns are handled and how effectively the school communicates about learning. This is a school that suits families looking for a single-sex Church of England secondary with a strong personal development focus, but who are aware that academic outcomes sit below the local average.
