International cricket
In addition to the one-day series and tournaments organised by the nations themselves, the ICC organises two One Day International tournaments. The World Cup is held every four years; it involves all the Test-playing nations and a number of teams advancing from the immediately preceding ICC World Cup Qualifier. The ICC Champions Trophy, previously known as the ICC Knockout Cup, is a shorter tournament held every four years in between World Cups. The ICC also organises a T20 International tournament, the ICC World Twenty20, which is generally held every two years and, as in the latest competition, involves the ten full ICC members and six associate members who qualified through a qualifier competition, the ICC World Twenty20 Qualifier.
Test cricket
There has been no World Cup for Test cricket conducted thus far by the ICC, since it is the longest format of the game, due to which the Championship might go on for years together. However, as of late, the ICC is holding discussions to conduct a World Test Championship over a span of 2 years (starting its first Championship from 2019–2021), after failing to execute their plan of conducting this tournament twice, once during 2013 and another time during 2017. The schedule for 2019–21 Test Championship is a set of typical bilateral series in various countries put together, where one team is the host and other team is the visitor. The length of the series would vary between 2 matches to 5 matches. The result of each match carries a weighting of the points depending upon the length of the series: a single match in a 5-match series will account for 20% of the series points, while a match in a 2-match series will account for 50% of the series points.
