The unofficial national circuit championship is the Tournament of Champions (LD) (TOC) held at the University of Kentucky. To be eligible for the TOC, debaters must collect at least two bids at various designated tournaments held throughout the year. (They cannot be considered qualifying tournaments because they technically exist independent of TOC authority and are significant in their own right.) These tournaments are granted a certain number of bids by the director of the TOC (Prof. Angela Reed) with the input of her advisory committee that debaters receive upon reaching a certain level in the elimination rounds. The level of elimination round at which bids are awarded is subjective, but depends chiefly on the size of the tournament, the perceived collective quality of the debaters in attendance, and the quality of the tournament itself (whether it is run well or not). There are fluctuations in tournaments' bid levels and the tournaments that have bids in the first place, but the major tournaments have very secure bids. For example, the Dowling Catholic Paradigm held at Dowling Catholic High School in West Des Moines, Iowa is a medium-sized tournament attended by debaters of all experience levels mostly from the Midwest, and therefore receives four bids, awarded to the debaters who reach the semifinal round of the tournament. The Glenbrooks tournament, considered among the most competitive regular season tournaments in the country, is attended by approximately 200 experienced debaters and has for many years had 16 bids to hand out to competitors who reach the octofinal round.
