The school was founded in the Gordons' family home on Georgia Street, Vancouver, with just four girls.

Sara E.G. Macdonald became Headmistress and in 1942, the school moved to the present 10-acre (4 ha) site on West 41st Avenue in Kerrisdale.

On the day of its 90th birthday, the school received its own coat of arms, granted by the Lord Lyon.

In Mathematics, French, English, Spanish, Mandarin and the Sciences, students who demonstrate high ability are given the opportunity to accelerate their programs, finishing grade 12 in their eleventh year.

This would allow them to pursue an enriched Board Authority/Authorized course designed to meet students' interests in Economics, World History, Calculus, European History, English Language, Literature, Physics, Chemistry, French, Spanish, Chinese, and Human Geography.

The academic programs at Crofton House School are very rigorous and only select students may participate in accelerated courses.

Proper outerwear is a blazer for assemblies and special events, or a cardigan, pullover, or fleece.
