About Tabroom.com


The goal of Tabroom.com is to provide a free & open source tournament management system to debate and speech tournaments worldwide, for as many formats of debate as possible.  The software that runs Tabroom.com is open source, and its free for anyone to use.  Hosting and support is provided by the National Speech & Debate Association.

The Tabroom system can pair IE and debate events, handles public pairings, enable judges to enter decisions and scores online, and publish and track results all online. It has limited support for Student Congress - it can handle the usual tiebreakers, assign chambers and publish rounds, though it cannot yet handle things like student preferential balloting. Tabroom also supports World's Schools format debates and World's University (British Parliamentary) format debates.

We also develop and host the optional CAT (Computer Assisted Tab), a desktop software client which pairs rounds, generates results, and can also generate paper ballots and printouts for tournaments that prefer to operate offline. CAT and Tabroom are also interoperable with Rich Edwards' TRPC program for debate tabulation.   For the most part, however, tabulation and pairing can and should all be done directly from the Tabroom website; only download and use the CAT if you've done so before. For more information, see the CAT/TRPC info page


Tabroom will support

  • Automatic online registration for tournaments
  • Team management features, including:
    • Student self-signup for tournaments with coach approval required
    • Parent & debate partner notification when a student signs up
  • Students and judges receive pairings and results by phone or SMS/Text
  • Pairings and schedules posted online automatically
  • Multiple systems of mutually-preferred judging (ordinals, tiers, etc)
  • Online entry of strikes/scratches & conflicts
  • Fully automatic generation of pairings, judge placements, rooms, etc.
  • Online and manual ballot entry
  • Pairings and judge placement for elimation rounds
  • Results generation & display, with reporting to leagues and circuits.

Tabroom aims to support as many formats of debate as possible.  Our current list includes:

  • WUDC style Parliamentary (4 teams)
  • US high school debate (Policy, PF, Lincoln-Douglas, Congress)
  • US/Canadian Parliamentary (2 teams)
  • US Individual Events (Interp, Extemp, etc).

If you have a format of debate that isn't on our list, please let us know at requests@tabroom.com. Please also test your format if you do not know that Tabroom has run your format or rules successfully before. There are a lot of settings in Tabroom but we cannot promise it will run your particular form of debate without testing before your tournament


The Tabroom system began as two projects; the CAT (Computer Assisted Tab) by Jon Bruschke of California State University at Fullerton (CA), and Tabroom.com by Chris Palmer of Lexington High School (MA).

The new integrated tabulation system and features were supported by a grant from the Open Society Foundations.  Tabroom support is now being sponsored as part of the Solutions Division of the National Speech & Debate Association (formerly the National Forensic League).  Tabroom is free and open for anyone to use.  Tabroom is also open source software; to browse the software repository, check out our Subversion repository.
