This rankings system was developed for the INF by statistician David Kendix.
The first list was published on 11 February 2008. The latest list has been updated on 26th September 2017 and includes matches up to 13th September 2017. The ranking list relates to senior teams of member countries that are playing regular international test matches. To find out more about how the system works read below and click here for Frequently Asked Questions.
A rating is a measure of the average performance of a team over a series of matches. Each team earns a certain number of points from each international match. Their rating is the total number of points earned divided by the number of matches played. The team with the highest rating is ranked first in the world. The next highest rating is ranked second and so on.
Weighting Matches played a long time ago are a poorer guide to current form than more recent results. Therefore past results are weighted, giving a lower weighting to earlier results. For the purposes of this list, matches played since July 2016 currently have a full weighting (100%). Matches played in the two previous years (July 2014-June 2016) have a weighting of 50%. Earlier matches are not directly included in the ratings at all.
Each July, the oldest year of results will drop out of the ratings and the weightings redistributed. This is the one annual occasion when the rankings list could alter other than through a match being played.
The number of points earned by a team for any match depends on two factors. The result (won, tied or lost) and the opponent against whom the result was achieved. The higher an opponent’s rating the more points are earned for beating them.
If a team wins a match they will earn 50 points more than their opponent’s rating. But if they lose, they will earn 50 points less than their opponent’s rating. Worked numerical examples appear in the Frequently Asked Questions.
It is not meaningful for a team to claim a world ranking if they have only played a small number of matches. As soon as a team has played eight International test matches over the rating period then they will have earned an official world ranking. If a team has played fewer than eight matches, they will still have a rating, but without a corresponding ranking. To have a ranking the team must have played at least 2 games against a rated team.
The following teams currently have a rating in the system and could become ranked once they have played 8 matches:

The INF World Rankings were reviewed at the INF Board Meeting in June 2012, with David Kendix, Statistician, who was retained by the INF to develop the ranking methodology in 2007.
Following a detailed discussion the Board was satisfied that we have a robust and reliable rankings system that presents a true reflection of the quality and standing of the performances of international teams and that this system can be used with confidence for qualification purposes.
