There are currently four divisions taking place biannually with promotion and relegation taking place between divisions. In 2010 Division One, for the first time, a Twenty20 tournament took place following the traditional 50 over competition.
The ICC Americas Championship first took place in 2000 between the five associate teams in the region. 2006 saw the championship evolve into a league system with three divisions allowing most of the affiliate nations in the region to participate. This coincided with the introduction of the World Cricket League, an ICC initiative to give all cricket playing nations a chance to qualify for the Cricket World Cup. In 2010, a fourth division was added meaning that all members in the region were able to take part in the league system.
Typically, the team finishing first is promoted and the lowest place team is relegated to the division below where possible. The only occasion this did not happen was in 2008 when Turks and Caicos Islands retained their Division Two spot despite finishing last.
The 2000 tournament was held in Ontario, Canada, at the Maple Leaf Cricket Club and G Ross Lord Park. Then affiliate member the Cayman Islands gained a surprise victory over Argentina, and the tournament itself went down to the final day. Canada and Bermuda were level on six points each going into their final game. Bermuda batted first and were dismissed for 186, with Dennis Archer top scoring with 59, with John Davison and Nicholas Ifill taking three wickets each for the home team. When Canada batted, they lost their first two wickets quickly, but Nicholas Ifill (completing a fine all-round performance with an unbeaten 78) and Joseph Harris (who scored 60) putting on a 122 run partnership, before Ifill and Paul Prashad steered them home for the seven wicket win.
The 2002 tournament was held in Argentina and saw the debut of the Bahamas. The home side were disappointed to go without a win, again losing to the affiliate member in the tournament. The USA won the tournament after rain washed out the final day, ending Canada's hopes of winning the tournament for the second time in a row.
The 2006 Division One tournament was held in Canada. The hosts started poorly, losing to Bermuda and the Cayman Islands, and were unable to repeat their 2004 performance, finishing third. The tournament was won by Bermuda for the first time. The tournament also functioned as qualifying for the World Cricket League for Argentina and the Cayman Islands (the other three were already in the tournament). The Caymans finished fourth, giving them a spot in Division Three in 2007, and Argentina a spot in Division Five in 2008.
The Division Two tournament was held from 3–5 April and was won narrowly by the hosts, Suriname. Three of the four teams finished on 8 points but Suriname were promoted due to having the highest net run rate. Although newly promoted Turks and Caicos Islands finished in last place they remained in the division for the 2010 competition.
The Division One tournament was held in Florida from 25–30 November and saw the hosts, USA winning fairly comfortably. As a result they now equaled Canada in winning the ICC Americas Championship twice. Suriname lost all their games and so were relegated back to Division Two for the 2010 competition.
Peru debuted in Division Three. Suriname gained a place in Division One, but was relegated later to Division Two, and Turks and Caicos Islands gained a place in Division Two, but was relegated later to Division Three.
The 2010 Americas Division Two was held from 1–6 February in Nassau, Bahamas. Bahamas won obtaining not only promotion to Division One, but also a place in 2010 WCL Division Eight. Newly promoted Brazil had a disappointing setback after their captain, Matt Featherstone, suffered a back injury just days before the team's departure. They lost all their matches and were relegated back to Division Three.
The 2010 Americas Division One tournament took place from 27 May – 7 June in Bermuda. The hosts were joined by Argentina, Bahamas, Canada, Cayman Islands and USA. It consisted of a T20 Tournament and a 50 over tournament where Canada was crowned the 50 over champion undefeated and Bahamas was relegated to Division 2 after a thrilling tie against Argentina in the last match. If they had won, Argentina would have been relegated to Division 2 on NRR. USA won the T20 Tournament beating Canada in the finals.
The 2011 Americas Division Three was held 13-20 March in Costa Rica. Belize won the tournament, while being undefeated, and qualified for 2011 Americas Division Two. But the hosts ended in 5th place. Cuba did not participate due to flight restrictions.
The 2011 Americas Division Two which took place from 10 to 17 April was held in Suriname and won by Suriname which qualified for 2011 Americas Division One. Panama, Belize, and Turks and Caicos had the same number of points, but were placed in their respective places by their net run rate. Brazil ended last place for the second time.
The 2011 Americas Division One took place between 17-24 July and was held in Fort Lauderdale, Florida, USA. Canada won the tournament for the 4th time and the hosts ended as runners-up and Argentina came back to Division Two that will be held in 2013.
