The Prep department, consisting of Years 3 to 8, is to be found as the main part of the school on Maori Road.
Over the course of Year 3 and 4 the transition is made from more class-based learning to specialist teachers so that by Year 5 all subjects are taught by specialist teachers in specialist rooms.
Years 5 and 6 take the boys through towards any possible Year 6 entrance exams and also SATs.
There are three classes in each of Years 3, 4, 5 and 6. For Year 7 and 8, boys focus on Common Entrance and Senior School Scholarship Exams. In these two year groups there are two classes.
