About St Mark's Catholic School
St Mark's Catholic School sits at the top of the Hounslow secondary school rankings, placing first out of 19 schools in the local authority based on Progress 8 scores. That puts it ahead of its nearest peers — Gunnersbury Catholic School, Reach Academy Feltham, and Nishkam School West London — and in the top five per cent of all state secondaries nationally. It is one of seven schools in Hounslow rated Outstanding by Ofsted, and the nearest other Outstanding school, Lampton Academy, is just over a kilometre away. The school is a Roman Catholic mixed secondary for pupils aged 11 to 18, with a capacity of 1,213 and currently 1,215 pupils on roll. The headteacher is Andrea Waugh-Lucas. In its most recent graded inspection in September 2022, Ofsted awarded the top grade across every category: overall effectiveness, quality of education, behaviour and attitudes, personal development, leadership and management, and sixth-form provision.
Academically, St Mark's is a high performer. Its Progress 8 score of 1.35 is well above the national average and significantly higher than the Hounslow LA average of 0.44. This means pupils here make around a grade and a third more progress per subject than the average student nationally. The Attainment 8 score sits at 64.7, and 92.4 per cent of pupils achieved a grade 4 or above in English and maths. The EBacc entry rate is high at 83.8 per cent, with 63.8 per cent achieving the EBacc at grade 4 or above. In the sixth form, the average points per entry is 39.73, equivalent to a B grade, and the best three A-levels average out at a B. The sixth-form value-added score is 0.07, which is in line with expectations, and the progress banding is rated as Average. The school's Progress 8 banding, however, is classed as well above average, reflecting the strong gains pupils make during Key Stage 4.
The school is heavily oversubscribed: for 2025/26 entry, there were 1,029 applications for 180 places, an oversubscription ratio of 5.72, with 168 first-preference offers made from 353 first-preference applications. Facilities include a chapel, sixth-form centre, sports hall, playing fields, tennis courts, science labs, music rooms, art studios, and an ICT suite. Sports offered include football, rugby, rowing, cricket, and martial arts, and there are clubs such as the Duke of Edinburgh's Award, Model United Nations, coding, and Young Enterprise. The school provides for a wide range of special educational needs, including autistic spectrum disorder, dyslexia, speech and language needs, and physical disabilities. This is a school for families who want strong academic outcomes in a faith-based setting, and who are prepared for a competitive admissions process.
