St. Margaret's School was founded by the Sisters of Mercy in 1888.

• It is a co-educational Catholic Day School with approximately 205 girls and boys between the ages of 2 and 11, with a strong ecumenical tradition respecting the faiths and cultures of all members of the Community.
• The school provides an excellent, well-balanced, quality education within a happy secure atmosphere based on sound Christian values.
• Pupils are drawn from a wide catchment area which spans West Sussex, Hampshire and Surrey.
• The school serves Senior Independent Schools in these areas.

The school is divided into:

• a Nursery department with boys and girls from the age of two.
• a Pre-preparatory department - Key Stage 1 pupils
• a Preparatory department - Key Stage 2 pupils.

St. Margaret's School is affiliated to the Independent Schools Association (I.S.A.) and although we are not obliged to follow the National Curriculum, its targets are regarded as a basic foundation, which we greatly extend by wider programmes of study.

Children transfer from our Nursery to the Pre-preparatory department at the age of 4 and develop within a challenging and supportive educational environment. All children are encouraged to develop their talents and to achieve their potential through an enriching and stimulating curriculum.
