All Associate Members of the ICC were eligible to compete in the league system, which featured a promotion and relegation structure between divisions.

[1][2] The initial league began in 2007 with seven tournaments over five global divisions, based upon previous world rankings.

The two last-placed teams in that World Cup Qualifier lost their ODI status and were relegated into Division Two.

In 2005, six associates were assigned One Day International status, based on their performance at the preceding World Cup Qualifier.

In 2017, Afghanistan and Ireland were both promoted to "Full" (test-match) status, leaving only four associate nations with ODI-status: after mid-March 2018 these were Scotland, Netherlands, UAE, and Nepal.

[8][9] Teams that have One Day International status are now included on the main ICC ODI Championship and are listed in the order they appear on that table.
