Christ Church Grammar School opened in 1910 as the Christ Church Preparatory School, on a site at the corner of Queenslea Drive and Stirling Highway in Claremont.
There was one classroom and an initial enrolment of nine day boys. Canon WJ McClemans, Rector of Christ Church and the school's founder, ran the School as well as carrying out his parish duties. The School has since grown into Perth's leading boys' school, with approximately 1400 boys from Pre-Primary to Year 12 engaged in a variety of innovative and student-focused academic and co-curricular programs designed to develop each boy's unique talents and interests.
The School maintains an archive of historically significant records and artefacts. Year 8 boys enjoy exploring the archives when studying the school's history Society & Environment lessons in Year 8 and it is also popular with old boys. A history of Christ Church will be published in 2010, the School's centenary year.
