The senior school has around 400 girls aged 11 to 18, and provides a coeducational sixth form in partnership with the nearby Elizabeth College. An associated preparatory school, Melrose, was opened in 1949 on the same site as senior school. As a selective school, prospective pupils must pass an entrance exam to be offered a place, although the school accepts pupils from a wide ability range. The school charges £3,740 per term, with three terms per academic year, as of 2020/2021.
