Extemporaneous Debate
Event Description:
Extemporaneous Debate (XDB)is a one-on-one debate event in which students are presented with a new resolution each round and have 30 minutes to prepare before delivering arguments, refutation, and rebuttals. Unlike traditional debate events, which focus on a single topic throughout a tournament, Extemp Debate introduces a variety of resolutions, testing students’ adaptability and critical thinking across a broad range of issues. The use of evidence is permitted, but due to the short preparation time, the event emphasizes reasoning, structure, and effective delivery over detailed research.
This event appeals to students who enjoy thinking quickly, tackling a wide range of topics, and engaging in real-time argumentation. While students with experience in debate or speaking extemporaneously may feel right at home, public speakers and interpers who are thoughtful, quick-witted, and curious can also find this format exciting and rewarding.
Successful students in Extemp Debate are often analytical, confident, persuasive, and logical thinkers with a broad base of knowledge and the ability to work independently under pressure.
