It teaches independence of thought and action in a nurturing learning environment.

Boarding has been a central part of Ascham from its earlier years and it has one of the largest enrolments of country boarders in NSW. Ascham’s 3.3 hectares of grounds and heritage buildings provide an oasis, only 5 minutes from Sydney’s vibrant cultural centre.
