Priorities for admission are: first current students, staff and founding/associate members; second siblings of current students; other applicants are considered as space allows; under equal conditions, offers go to the student with the best previous academic record. There is a learning support program, but applications with severe emotional needs cannot be catered for. Documentation and an interview are required. OIS accepts applications throughout the year (Rolling Admissions) if space becomes available. English language requirements vary by grade; a minimum level is advised, fluency is not compulsory for admission to certain year groups, and full proficiency is required for Years 10–13 and will be assessed during admissions. The admissions steps are: register your interest; complete the application form and pay the €250 application fee; schedule placement tests; attend an interview with the programme coordinator; Admissions Committee reviews the application; upon successful completion, upload the required documentation and pay the registration fee to secure the place; if there is no space, the applicant will be placed on the waiting list.
