This culturally diverse school serves the communities of San Diego County and Tijuana, Mexico.

The school also publicly states, "We open our doors to all boys we believe will benefit from our academic program."

Many of the school's religious staff were trained at Villanova University and Merrimack College, which are both run by the Order of Saint Augustine.

In September 1978, PSA Flight 182 crashed and exploded several blocks (Nile and Dwight Streets) from the campus.

The school shut down and became a triage and command and control center for those authorities who responded to the emergency posed by the crash, culminating in the utilization of the gymnasium as a makeshift morgue.

The biggest change during this era was the creation of an on-campus parking lot and the closure of a portion of Bancroft Street, which previously divided the campus into two separate sections.

The second phase consisted of the new Saint Augustine Commons, a multipurpose gymnasium, and meeting space.

However, some students have longer commutes from areas in the North (such as Carlsbad, Del Mar, Valley Center, Escondido, and Oceanside), the East (such as Poway and Lakeside), and the South (such as Chula Vista, Eastlake and Bonita.)

Most students are Catholic; however, the school accommodates people of other faiths, including non-Christian ones and some degree of non-faith in personal belief.

On Tuesdays and Fridays, all teachers have office hours, allowing students to ask questions or receive help with assignments.
