Archbishop Riordan High School

Archbishop Riordan High School combines rigorous college-preparatory academics with Marianist values, aiming to develop students intellectually, spiritually, and socially in a community grounded in faith, inclusion, service, and justice. Its teaching emphasizes critical thinking, clear communication, hands-on learning, and applying knowledge to real-life situations; assessment is intended to reward mastery and revision rather than simply accumulating points.
