Chicago participates in parliamentarian debates under the the American Parliamentary Debate Association, which is an entirely different program from NDT. It IS a powerhouse team on APDA.
“The Chicago Debate Society is the parliamentary debate team of the University of Chicago. We compete on the American Parliamentary Debate Association circuit and send debaters to tournaments almost every weekend. CDS has consistently met tremendous success on APDA, qualifying teams to Nationals every year and routinely winning Speaker and Team Awards at tournaments.”
