The Women's Flat Track Derby Association (WFTDA) is an association of women's flat track 
In 2004, the ULC was an informal electronic message board through which established leagues compared notes in order to prepare for interleague play, and it was also used to exchange information to help new leagues that were just getting started.
The ULC evolved into a more formal organization in July 2005, when representatives of 20 leagues met in Chicago to discuss establishing a governing body for women's flat-track roller derby. At the meeting, a voting system was established, as was a set of goals and a timeline was established for facilitating interleague play. Among these goals was the production of a standard track design and standard game rules. The design and rules which were settled upon and distributed later that year. In November 2005, the ULC voted to change its name to the Women's Flat Track Derby Association.
In early 2006, a track design and rules were published on the organization's fledgling web site. By that time, the organization had grown to 30 leagues, a cap decided upon at the July 2005 meeting.
Induction of new member leagues was postponed until revised membership requirements could be discussed at the next face-to-face meeting, scheduled for the end of May. However, in February 2006, soon after the initial requirements were published and following the fragmentation of several leagues, a "multi-league per city" clause was added to the membership requirements. Although throughout early and mid-2006 the clause was listed as a requirement for membership, WFTDA's web site was later updated to state that the policy is "unofficial". WFTDA also claims the policy is intended to uphold goodwill between members — by excluding leagues not likely to find favor with established members — as well as to prevent rival leagues in the same city from being privy to each other's "proprietary information."
Following the May 2006 meeting, a press release was issued to promote the organization and publicize the meeting. The June statement covered the following points:
- Representatives of the "30 founding leagues" met to discuss rules, business structure, skill standards, rankings and future tournaments.
- 30 more leagues were slated to be inducted in mid-2006, bringing the total membership to 60.
- Version Two of the WFTDA Flat Track Derby Standardized Rules for Interleague Play was announced as forthcoming in mid-2006.
- Changes to the member league divisions were announced (see table below).
- A 2007 tournament schedule was announced.
In addition, Eastern and Western divisions, delineated by the Mississippi River, were announced. Thus, each member league is either Eastern or Western, and Division 1, 2 or 3. In September 2006, new membership was reopened.
By late August 2007, WFTDA membership was up to forty-three leagues. On August 15, 2007, WFTDA announced it had struck a deal with the MavTV network to record, edit and broadcast the 2007 Eastern Regional Tournament as a weekly series of 12 one-hour episodes (one episode per bout).
In mid-2007, WFTDA's Web site was updated to reflect changes in the requirements for placement in the three divisions: it is now based on seniority, as measured by readiness for inter-league play and the number of seasons completed while a WFTDA member (see table below).
In September 2007, WFTDA was admitted to 
In June 2008, the WFTDA Rules Committee created a Question and Answer forum to "provide definitive and final answers about the Women’s Flat Track Derby Association Standard Rules.
In July 2008, WFTDA began a referee certification program.
In September 2008, WFTDA had grown to 60 leagues, and the official WFTDA magazine fiveonfive began publication.
In November 2008, a flyer was published announcing that for 2009, WFTDA member leagues would be divided into four regions, rather than two: West, South Central, North Central, and East. Each region has a tournament scheduled, followed by a national championship.
Also in January 2009, the WFTDA announced it would stop accepting applications for new membership from February until July, so that it could concentrate on internal restructuring in order to, among other things, "grow the scope" of the organization.
In April 2009 the WFTDA published revised rules, WFTDA Rules 4.0. The revised rule-set became effective for all WFTDA sanctioned bouts on June 1, 2009.
In May 2009, the first officially sanctioned international WFTDA bout was played between Montreal Roller Derby and Harrisburg Area Roller Derby at the Olympic Skating Center in Enola, PA.
In July 2009, the WFTDA announced its new apprentice program for aspiring member leagues that replaced its traditional membership application process. The program is designed to act as a "WFTDA 101" tutorial, and will match new leagues with an established WFTDA mentor, who will guide the apprentice through the processes and requirements necessary to becoming a full member. Upon completion of the program, apprentice leagues will have the knowledge (and the recommendations) needed to apply for full WFTDA membership.
In June 2010, the WFTDA announced the first round of Apprentice league graduates, and formed two new regions outside of the United States. (Leagues in those regions will compete in the closest US region until they develop more fully.)
In June 2013 the Rock n Roller Queens of Bogota, Colombia become the first full member South American league. The Tokyo Roller Girls and Kokeshi Roller Dolls become the first full member leagues in Asia.
Each year a series of playoffs are held, based on the June 30 rankings. 40 teams compete in four Division 1 Playoff Tournaments, and the top 3 finishers from each tournament go on to the WFTDA Championship Tournament. The next 20 eligible teams compete in two Division 2 Playoff Tournaments, with the winners of each tournament meeting at the WFTDA Championship tournament, with the winner crowned the Division 2 champion.
WFTDA league divisions
In 2013 WFTDA changed divisions and expanded the playoff tournament structure. After the November 30 rankings release of each year, each league is placed within a competitive division for the next 12 months based on their charter team's rank. The leagues remain in their division for 12 months, no matter what their rank is in subsequent rankings releases.
A league's division placement determines the game play minimums for their WFTDA charter team in the following year. A Division 1 team must play no less than four WFTDA Sanctioned games, with at least three of those games against other Division 1 opponents and the fourth against either a Division 1 or Division 2 opponent, before June 30 of the following year. A Division 2 team has to play a minimum of three WFTDA Sanctioned bouts, two against Division 1 or 2 opponents and the third against an opponent in any division. A Division 3 team must play a minimum of two WFTDA Sanctioned games against any opponents.
Division placement does not affect which playoffs a team qualifies for, only minimum game play requirements. If a Division 2 or 3 team moves up the rankings into the top 40 at the time of tournament seeding that team will be invited to Division 1 Playoffs. Similarly, a Division 1 team moving down the rankings will receive an invitation befitting the team's rank at the time of seeding.
As of May 2014, 115 leagues are enrolled in WFTDA's Apprentice Program:
Many roller derby leagues that are not WFTDA members use the WFTDA rules.

At the conclusion of each year's competitive season (immediately following that year's WFTDA Championship) final rankings for the year are issued. The top 40 leagues are placed in Division 1, the next 20 in Division 2, and the remainder in Division 3.
