Students entering Form 3 at Auckland Grammar School must realise that this year is the start of a five-year programme which will lead to University Entrance and further study at tertiary level. A small number of students will leave at the end of Form 5 or Form 6 for a variety of courses and reasons, but essentially the Senior School Programme at Auckland Grammar School should be viewed as a three-year commitment, beginning at Form 5.The success of Auckland Grammar School students in external academic examinations is well known and we regard it as our first priority to ensure all students achieve the best examination results of which they are capable. Students must be prepared to work hard and tackle the requirements of the rigorous, advanced courses on offer; in return the School is committed to giving students at all levels the very best in teaching, guidance and support to ensure all students achieve to the best of their abilities.
