Stone Bridge competes in the Liberty District of the Northern Region for debate competitions. These are the same districts that Stone Bridge athletics are in, because debate is sponsored by the Virginia High School League. The debate program won the AA state title in 2005, and the AAA state title in 2006. The debate team participates in 3 debate events (Policy Debate, Public Forum Debate, Lincoln-Douglas Debate) and Speech. The team participates at local tournaments hosted by the Washington-Arlington Catholic Forensics League (WACFL) as well as several tournaments out-of-state.
