Lincoln-Douglas Debate

Lincoln-Douglas debate is a one-on-one format centered on a value resolution — a philosophical proposition that competitors defend and challenge using a value and criterion framework. The format is named for the famous 1858 Illinois Senate debates and has been a cornerstone of high school forensics for decades.

Each round features an Affirmative debater defending the resolution and a Negative debater challenging it. Competitors alternate through structured speech and cross-examination periods, with the Affirmative speaking first and last. A typical LD round runs approximately 35–40 minutes.

MIFA LD follows the national topic schedule maintained by the National Federation of State High School Associations (NFHS). Coaches and competitors should consult the current MIFA rules document for topic dates and specific timing rules.

Parliamentary Debate

Parliamentary debate is a team format modeled loosely on the British parliamentary tradition. Two-person teams — a Government team defending the motion and an Opposition team challenging it — alternate through a series of speeches, with interjections and points of information permitted during specified windows.

Unlike Lincoln-Douglas, Parliamentary debate emphasizes in-round argumentation over prepared cases. Topics are often announced shortly before the round, testing teams’ ability to construct arguments quickly, think critically under pressure, and respond to opponents’ arguments in real time.

MIFA Parliamentary debate provides an excellent entry point for students interested in debate but who prefer a more collaborative and spontaneous format. The event builds teamwork as well as individual argumentation skills.
