Initially established as a Single-sex school for boys only, prior to 2019, the School was co-educational from Year K to Year 6, and in Years 7, 8 and 11 in the Senior School; and in Years 9-10 and 12, the School catered for boys only. Since 2019 the School has been fully co-educational. Boarding facilities for Senior School girls were introduced from 2020.

The Anglican grammar school traces its origins back to 1896 when it was established by Charles Harper. In 1900, the school moved from the Harper family home to its current site near the banks of the Swan River, approximately 15 km (9.3 mi) from the centre of the City of Perth on 80 hectares (198 acres) of property. The East Guildford campus consists of a senior school for Year Seven to Year Twelve, a preparatory school for kindergarten to Year Six, sporting grounds and boarding facilities for 150 students.
