The school's entrance examinations were open to all Saudis. Some lower class Saudis were granted acceptance and attended the school with wealthier Saudis. Around that era, each graduating class consisted of around 60 boys.

Coll said in the 1960s and early 1970s that the school "had a relatively secular flavor."
