WFTDA-charter teams compete for mathematically calculated rankings, and at the end of the Competitive Season (February 1 – June 30) are seeded into postseason tournaments (WFTDA Continental Cups and International WFTDA Playoffs & Championships) based on those rankings.
Post-season tournaments International WFTDA Playoffs and Championships Each year a series of playoffs are held, based on the June 30 rankings. While the top four teams as of June 30 get an immediate bye to Championships, the next 24 teams are seeded into two Playoff Tournaments, historically termed as
Division 1, with the top three finishers at each advancing to Championships. This was down from the top 36 teams competing in three Division 1 Playoffs in 2017, when the top four finishers from each tournament advanced to Championships without any bye teams. The Hydra Trophy is awarded annually to the top ranked team determined by the International WFTDA Championships tournament. The 2020 Intentional Playoffs and Championships were cancelled due to the
COVID-19 pandemic.
Continental Cups Charter teams ranked below the cutoff for playoffs are seeded into geographically-based Continental Cups, replacing the former
Division 2 system, which in 2017 saw the next 16 eligible teams compete in a single Playoff Tournament, with the winner crowned Division 2 champion. The 2018 announcement described the model for Continental Cups as "scalable", such that event numbers and sizes may change over time based on needs. The Division structure has now been replaced by an updated version of the geographic regional divisions since 2024. In 2013 WFTDA changed
ranking systems from a regional, poll-based format released quarterly to a system based on the competitive ranking of teams using game results. When the organization did so, WFTDA introduced competitive
divisions and expanded the playoff tournament structure. After the November 30 rankings release of each year, each league was placed within a competitive division for the next 12 months based on their charter team's rank. The leagues remained in their division for 12 months, no matter what their rank was in subsequent rankings releases. Through 2016, the top 40 leagues from the November 30 rankings were placed in
Division 1, the leagues ranked 41-100 (from 2015, those ranked 41-60) were put in
Division 2, and through 2014 all other member leagues were grouped in
Division 3. Each region had a tournament scheduled, followed by a national championship. As of 2024, WFTDA has returned to operating under six geographic league divisions. The divisions are Europe (EUR), Latin America (LATAM), North America Northeast (NAE), North America South (NAS), North America West (NAW), and Oceania (OC). In addition to the global regional divisions, they added a Geographically Unrestricted Region (GUR) for teams wishing to play teams outside of their regional division. Until a team has played a team in another regional division, it will not have a GUR ranking. == Roller Derby Certification Program for Officials ==
