Cathedral's primary entry points are in Kindergarten, and later in 5th and 6th grades where class sizes grow from 24 to 36 students.

For special occasions, students also wear a blazer with the school crest embroidered on the chest.

Cathedral competes against other private schools in San Francisco and the Bay Area, and it uses its on-site gymnasium and nearby city fields as facilities.

Classes in those subjects are mandatory from kindergarten to eighth grade, and all students participate in one drama performance every year.

Students in grades 3–8 participate in the Field Foundation Public Speaking Competition annually.
