In 2016, Archbishop Riordan expanded their curriculum offerings to launch a four-year honors engineering program track.

Students apply to the program when applying to the school and are accepted based on their 7th and 8th grade math and science grades, performance on standardized tests, demonstrated ability to handle a rigorous course load, and demonstrated interest in the area of engineering.

Archbishop Riordan High School operates a residential boarding program with students from nine countries currently living on campus.

Within each house, students are divided into "R-Time" rooms, a homeroom classroom they remain in throughout their four years at Riordan and meet with nearly every morning.

The four houses work together to participate in community service events and compete in intra-school competitions, such as the Crusader Games and Frosh Olympics.

In 2010 and 2012, the band was invited to perform as part of the San Francisco Giants Victory Parade down Market Street.

They also played at the 2013 America's Cup in San Francisco, Super Bowl 50, and the New Year's Day Parades in Rome (2017 & 2024), and London (2019).

The Riordan Crusaders field a variety of team and individual sports in the West Catholic Athletic League (WCAL).

Sports that Riordan fields include football, cross country, wrestling, basketball, soccer, track, volleyball, swimming, tennis, baseball, sailing and golf.

Participating in the newly created Catholic League for high schools around San Francisco, the student body enthusiastically supported the program, as Riordan fielded new sports every few years.

Sports at Riordan were initially shaped by Edward Fennelly, a then 24-year-old graduate of St. Joseph's High School in Alameda.

These trophies, signed by the team, reside in the Crusader Forum today, memorializing their legendary upset for the first WCAL championship.

The varsity soccer team won four consecutive WCAL titles and the Central Coast Section championship in 1976.

Original organized leagues included baseball, football, soccer, basketball, pee-wee golf, tennis, track, field hockey, tumbling, wrestling, and bowling.
