Senior School Destinations
The excellence in teaching and learning at Arnold House is reflected in the impressive range of schools to which the boys go when they leave. Generations of pupils have gone, via Common Entrance and Public School Scholarships exams, to leading senior schools: in London, City of London School, Highgate, Mill Hill, St. Paul's, University College School and Westminster; others have left Arnold House to board - and many still do - at Bryanston, Charterhouse, Eton, Harrow, Marlborough, Oundle, Radley, Rugby and Winchester to name but a few of the many schools for which Arnold House pupils have successfully qualified.
