The Marist School
Ascot, Windsor and Maidenhead, South East · SL5 7PS
A small Catholic school in Ascot, The Marist educates pupils from the age of two right through to 18, with around 447 currently on roll. Its compact scale is part of its character: this is a community where children are known individually rather than lost in a crowd. The Independent Schools Inspectorate awarded its most recent inspection the top grade of 'excellent', extending the same judgement to pupils' personal development, and all compliance standards were met. Led by Head Mrs Joanne Smith, it takes its main 11+ intake at age 11 and welcomes both boys and girls.
