BGMs are now held at each World Scrabble Championship (taking place every odd year), and there are currently 24 member organisations.
Its main functions are to promote global recognition of Scrabble as a serious competitive activity; to provide for the benefit of members in pursuing the game; to further the best interests of Scrabble and international tournament players; to represent such players in dealings with other bodies, including the trademark owners of the game; to promulgate and encourage international convergence towards common standards and norms (including international rules, word lists and ratings); to organise global competitions and events; to publish relevant material; and to maintain a website for the benefit of the game and its players.
Following a six-month worldwide consultation process, the first version of WESPA's rules for global Scrabble was released in August 2009.
CSW is therefore substantially larger than TWL and has a more international flavour, including a number of local or dialect words from around the world.
WESPA has undertaken to host biennial world events from 2015 onwards using the old WSC format, with teams qualifying from national organisations.
In the seventh and final game, Alastair Richards of New Zealand won the title with a 13-point lead, defeating Australia’s David Eldar.
In 2023, the fifth WESPA Championship in Las Vegas was won by David Eldar, who defeated Harshan Lamabadusuriya to capture the $10,000 first prize in a four-day, 32-game tournament.
The Youth committee has also been active in promoting the game among young players worldwide, including training workshops held in various locations.
The WESPA committee is made up of nominees representing member nations, and the current Chair is Elie Dangoor (UK).
