Entry into Year 7 is managed through the NSW Department of Education - High Performing Students Team. Applications open in October of each year (when the applicant is in Year 5). More information about the selective school placement test can be found here.
Entry into Years 8-10 is limited with vacancies occurring only when a current student leaves the school. Applications are reviewed and a short list of the top twenty applications are established. When a place becomes available, candidates on the short list will be interviewed and a place offered.
Entry into Year 11 is through application. Applicants are required to sit an entrance test. Applicants are shortlisted according to their Acer HAST results and merit of application.
