Pittwater House is an independent, non-selective, non-denominational school offering a private school education for students from pre-school to Year 12. It offers a unique twin school environment in which the Boys Grammar School and the Girls College mix on the same campus but are predominantly educated in single-sex classes, showcasing the best teaching practices of both approaches. Pittwater House is a smaller school, fostering individual attention for each student and a real understanding of each student's abilities, talents and expectations. It provides quality education that caters for every student's individual learning needs, including gender, ability and styles of learning.

The institute has a strong academic focus at Pittwater House and the pursuit of academic excellence is fundamental to the structure of the academic program and is complemented by extensive pastoral and leadership opportunities. Its academic approach is constantly reviewed and refined to accommodate best practice in and beyond the classroom. The School has pioneered this approach based on an understanding that boys and girls learn differently and as a result they are able to tailor teaching styles to suit these differences, while also bringing boys and girls together for a range of activities and interactions. To ensure that child feels supported and encouraged throughout their time at school, Pittwater House has well developed strategies in place to ensure a positive transition for all stages of their journey throughout their school life.

The School is located in Collaroy, on Sydney's picturesque Northern Beaches, and is run coherently in three divisions.
