Iles was most active in organising various extracurricular activities, with a view to developing students' all-roundedness. He had established the house system, in which students were divided into different houses upon arrival to the school. This intensified the competitive spirit within inter-house competitions, such as the Swimming Galas and the Athletic Meets. Speech Day and Open Day were first held during Iles's headship. The college newspaper, "Torch", was first published in 1964, making it the earliest school publication in Hong Kong. School teams joined various Hong Kong inter-school activities and competitions. In 1968, the school established its first Chinese Society to remind students of the importance of learning traditional Chinese culture in "the reciprocal cultivation of English and Chinese literature and the diffusion of Christianity".
