National Parliamentary Debate Association

The National Parliamentary Debate Association (NPDA) is one of the two national intercollegiate parliamentary debate organizations in the United States. The other is the American Parliamentary Debate Association. Its membership is national with participating schools throughout the country. In 2015, NPDA was the largest debating organization in the United States with around 200-250 participating schools in any given year.

The Rules of NPDA Debate
In tournaments sponsored or sanctioned by the NPDA, teams of two debate head-to-head. Tournaments issue a new topic each round, generally on issues such as politics, philosophy and current affairs. After the announcement of the topic, the two teams have a limited preparation time, which is 15 minutes plus the time it takes to walk to the furthest away round in which debates will be taking place (usually rounded to 20 minutes), during which to write out their respective cases.

The standard time limits for an NPDA debate are:
 * Preparation Period: 20 Minutes
 * First Proposition Speaker: 7 minutes
 * First Opposition Speaker: 8 minutes
 * Second Proposition Speaker: 8 minutes
 * Second Opposition Speaker: 8 minutes
 * Opposition Rebuttal: 4 minutes
 * Proposition Rebuttal: 5 minutes

There are tournaments, however, at which these are modified, generally to a 7-7-7-7-5-5 format. The Claremont Colleges tournament, for instance, uses this 7-5 format. During constructive speeches, debaters may introduce new arguments and the speaker's opponents may rise to ask questions of the speaker. Constructive speakers can accept or reject any given question. Rebuttals are exclusively for summarizing the arguments that were made during constructives.

Over the past few years, many coaches and competitors have referred to the official title of speeches with different names. These are unofficial yet very popular with many judges:
 * Prime Minister Constructive
 * Leader of Opposition Constructive
 * Member of Government Constructive
 * Member of Opposition Constructive
 * Leader of Opposition Rebuttal
 * Prime Minister Rebuttal

Debaters may not bring in printed, published evidence and consult it during the round. It is expected that debaters will use their own pre-existing knowledge and research conducted prior to the start of the actual round to back their arguments with reasoning and empirical data. This places parli in stark contrast to the other common intercollegiate debate format, policy debate, where debaters may utilize quoted evidence.

The NPDA Championship Tournament
The NPDA runs one debate tournament each year: the NPDA Championship Tournament, held in late March or early April at rotating host sites. While the inaugural tournament in 1994 only hosted around 40 teams, the 2004 Championship Tournament had over 300 in the field from over a half-dozen nations. The tournament's practices are generally modeled by smaller invitational tournaments, which provide the bulk of year-long competition. NPDA sanctions many of these tournaments, and the school that does the best at sanctioned invitationals over the course of the year is awarded a year-long sweepstakes championship.

Relationship to other tournaments and organizations
There are usually several NPDA-sanctioned invitational tournaments in the US to choose from on almost every weekend of the academic year. The largest of these tournaments include the Mile High Swing held in Januaryd co-hosted in recent years by Texas Tech University and the University of Utah in Salt Lake City, Utah, the season-opening Bowman Debates at William Jewell College in September, the Steve Hunt Classic held at Lewis & Clark College in October and the Paul Winters Invitational at the University of the Pacific in November.

Communicating between tournaments
Almost from its inception, the NPDA community has taken advantage of the Internet to continue debates (and to debate about debates) between tournaments and in the off-season. For years, this took place via the official electronic mailing list, much to the chagrin of those who saw that resource as best used for official communication such as posting tournament invitations and results.

Today, much of the online debate (especially between competitors) in the NPDA community takes place via the online forum Net-Benefits.net, founded by University of Southern California then-undergraduate Jed Link. The name "Net-Benefits" is a pun, referring to the debate paradigm by which the debate judge weighs the net benefits of two competing policies. The site is now an electronic hub for discourse and information on parliamentary debate.

NPDA National Champions
Every year since 1994, the organization has held a national championship tournament. Winning teams include:
