Evidence shows that single sex education is more effective for girls allowing them to excel in all areas of the curriculum. As Scotland's leading all girls' boarding school, Kilgraston recognises that girls mature differently from boys and therefore provides an education geared to the individual needs of its pupils, with no limitations on their academic and personal ambitions.

That said, socialising is actively encouraged and there is a busy programme of joint events and socials with neighbouring schools, and also the all boys Merchiston Castle School in Edinburgh (where there are reciprocal arrangements for fees).

Kilgraston encourages leadership, confidence, independence, integrity and an ambition to achieve and has something to inspire every young woman, from rock climbing and karate; to photography and ceramics. This approach to education ensures that Kilgraston girls are well equipped for the modern world, whatever and wherever they want to be.
