Our slogan 'Educating for Tomorrow, Today' encapsulates a focus on being forward looking in readiness for the complexities of the world in which the boys will live. The school is of a size where every boy is known personally. The School has two classes in each Year group and a total of nearly 300 students in the fourteen classes. A five day a week Program called Early Entry is available for 4 year olds. The Staff/Pupil ratio is very favourable with smaller class sizes and Teacher Assistants in each class in each of the first four years of schooling. This is designed to help personalise education and maximise learning opportunities at a boy's point of need, in his academic program. Mosman Prep fosters a comprehensive approach to education that emphasises thinking, valuing and doing and occurs in the context of a personalised, Christian philosophy. This enables our boys to excel in academic and sporting pursuits, and in a wide range of expressive arts.
