Wahroonga Preparatory School began at St. John’s Presbyterian Church Wahroonga in 1926, in response to the need for a school in Wahroonga. Headed by Miss E. Whyte, the school opened with 11 pupils enrolled at a fee of 4 guineas per term, and at the end of the first year, enrolment at Wahroonga Prep had increased to 19. Initially lessons were held in the Church hall, and this occurred again during World War 2, which meant that the children had to be taken on long walks when funeral services were being conducted.
Over the years Wahroonga Prep has undergone many changes, building extensions, upgrades and improvements, particularly in recent years. An extensive rebuild of the building and playgrounds in 2010 has transformed the school, the playground areas and staff amenities.
Today, Wahroonga Preparatory School honours the traditions of its history by not only continuing to maintain the highest standards in education, but also by setting new standards in both learning and personal development. By respecting the past, yet embracing the future, Wahroonga Prep continues to offer a learning environment that is both remarkable and unique.
