The ICC ODI Championship is an international competition run by the International Cricket Council in the sport of cricket for the 10 nations that play Test cricket and Kenya, a non-Test country with full One-Day International (ODI) status. The competition is notional in the sense that it is simply a ranking scheme overlaid on all international matches that are otherwise played as part of regular ODI cricket scheduling. Other non-Test countries with One-Day International status aren't included as a minimum number of matches need to be played within a certain time limit.

In essence, after every ODI match, the two teams involved receive points based on a mathematical formula. The total of each team's points total is divided by the total number of matches to give a 'rating', and all eleven teams are ranked by order of rating (this can be shown in a table).

By analogy to cricket batting averages, the points for winning an ODI match are greater than the team's rating, increasing the rating, and the points for losing an ODI match are always less than the rating, reducing the rating. A drawn match between higher and lower rated teams will benefits the lower-rated team at the expense of the higher-rated team. An 'average' team that wins as often as it loses while playing a mix of stronger and weaker teams should have a rating of 100.

The calculations for the Table are performed as follows:

Each team scores points based on the results of their matches.
Each team's rating is equal to its total points scored divided by the total matches played. (Series are not significant in these calculations).
A match only counts if it was played in the last three years.
Matches played in the first year of the three-year limit count one-third; matches played in the second year count two-thirds; matches played in the last year count fully; essentially, recent matches are given higher weighting.
To determine a team's rating after a particular match:
- Determine the match result (win, loss, or tie)
- Calculate the match points scored:
  - If the gap between the ratings of the two teams at the commencement of the match is fewer than 40 points, then:
    - The winner scores 50 points more than the opponent's rating
    - The loser scores 50 points fewer than the opponent's rating
    - Each team in a tie scores the opponent's rating
  - If the gap between the ratings of the two teams at the commencement of the match is more than or equal to 40 points, then :
    - The winner, if it is the stronger team, scores 10 points more than its own rating
    - The winner, if it is the weaker team, scores 90 points more than its own rating
    - The loser, if it is the stronger team, scores 90 points fewer than its own rating
    - The loser, if it is the weaker team, scores 10 points fewer than its own rating
    - The stronger team in a tie scores 40 points fewer than its own rating
    - The weaker team in a tie scores 40 points more than its own rating
- Add the match points scored to the points already scored (in previous matches as reflected by the Table) and determine the new rating.

Australia were top of the inagural championship table in October 2002, and remained there until February 2007, when South Africa overtook them during the run up to the world cup.
