According to World Rugby the "top side in the World will normally have a rating above 90",[3] however, this is not always the case. New Zealand retained the number 1 position in August 2019 following defeat by Australia at Perth in the Rugby Championship, despite their ratings falling to 89.04. A week later, Wales increased their rating to 89.43 and claimed the top spot by beating England at Cardiff in a World Cup 2019 warm-up test. In contrast, some countries that have reached a rating of over 90 rating points, such as Australia (91.75) and Ireland (91.17), did not achieve the top spot, although Ireland would eventually reach the top of the summit with a rating of 89.47 following their victory over Wales in a World Cup 2019 warm-up test in Dublin, while Australia still to date have never attained the number 1 ranked position. This is due to the success of New Zealand who had been rated above 90 rating points for a record of 509 weeks and 6 days (from 2 November 2009 to 11 August 2019), which ended following the aforementioned defeat to Australia.

New Zealand also holds the record for the highest rating points amassed by any team, which currently stands at 96.57. England first held the record at 93.99 on the 24 November 2003, following their World Cup win in Australia; however, New Zealand surpassed this on 28 August 2006 with a rating of 94.62, following their Tri Nations victory over South Africa in Pretoria. The All Blacks would go on to push this record further over the years, reaching 95.01 points on the 25 June 2007 after beating South Africa in Durban, 96.10 points after their 2015 World Cup win in England and 96.30 points on 22 August 2016, following their Rugby Championship victory over Australia in Sydney, to its current record of 96.57, which they attained on 10 October 2016 after defeating South Africa in Durban. New Zealand's defeat by Ireland at Soldier Field, Chicago as part of the Autumn International Test Series in November 2016 ended their record streak.

The system ensures that it is representative of the teams' performance despite playing differing numbers of matches each year, and the differing strength of opposition that teams have to face. The factors taken into account are as follows:

• Match result
• Match status
• Opposition strength
• Home advantage

For each match played points exchanges are awarded for the following five outcomes and was developed using results of international matches from 1871 to the present day:

• a win or loss by more than 15 points
• a win or loss by up to 15 points
• a draw

Different matches have different importance to teams, and World Rugby has tried to reflect this by using a weighting system, where the most significant matches are in the Rugby World Cup Finals. Points exchanges are doubled during the World Cup Finals to recognise the unique importance of this event. All other full international matches are treated the same, to be as fair as possible to countries playing a different mix of friendly and competitive matches. Matches that do not have full international status do not count.

A win against a very highly ranked opponent is a considerably greater achievement than a win against a low-rated opponent, so the strength of the opposing team is a factor. Thus match results are more important than margins of victory in producing accurate rankings. This is because when a highly ranked team plays a lowly ranked team and manages to beat them by over 50 points, it does not necessarily indicate how either team will perform in the future.

When calculating points exchanges, the home side is handicapped by treating them as though they are three rating points better than their current rating. This results in the home side gaining fewer points for winning and losing more points for losing. Because of this, ideally, any advantage that a side may have by playing in front of their home crowd is cancelled out.

[1] Take the pre-match Points Ranking Score of Team Y. If Y has home advantage, add 3 to its pre-match Points Ranking Score. This is the “Modified pre-match Points Ranking Score” for Team Y. Call it “A”.

[2] Take the pre-match Points Ranking Score of Team Z. If Z has home advantage, add 3 to its pre-match Points Ranking Score. This is the “Modified pre-match Points Ranking Score” for Team Z. Call it “B”.

[3] Calculate the Difference between the two “Modified pre-match Points Ranking Scores”. Call it “D”.

[4] Apply the formula from the relevant item in this list:

World Cup Matches

... Team Y wins by 16 or more points ............... (10+B-A) x 0.3 capped at 6

... Team Y wins by 15 or fewer points ............... (10+B-A) x 0.2 capped at 4

... The match is a draw [**see note 9] ............... D x 0.2 capped at 2

... Team Z wins by 15 or fewer points ............... (10+A-B) x 0.2 capped at 4

... Team Z wins by 16 or more points ............... (10+A-B) x 0.3 capped at 6

Other International

... Team Y wins by 16 or more points ............... (10+B-A) x 0.15 capped at 3

... Team Y wins by 15 or fewer points ............... (10+B-A) x 0.1 capped at 2

... The match is a draw [**see note 9] ............... D x 0.1 capped at 1

... Team Z wins by 15 or fewer points ............... (10+A-B) x 0.1 capped at 2

... Team Z wins by 16 or more points ............... (10+A-B) x 0.15 capped at 3

[5] The team with the higher “Modified pre-match Points Ranking Score” may be termed the “Favourite”.

[6] The team with the lower “Modified pre-match Points Ranking Score” may be termed the “Underdog”.

[7] A team whose “Modified pre-match Points Ranking Score” is 10+ points lower than their opponents’ "Modified pre-match Points Ranking Score” may be termed the “Outsider”.

[8] An "Underdog" stands to gain more from a victory than does a "Favourite".

[9] In the case of a draw, the points are transferred from the “Favourite” to the “Underdog” or “Outsider”. The transfer is capped at 1 (2 in a World Cup Match).

[10] There is no transfer of points if a “Favourite” beats an “Outsider”.

All new member nations start with 30.00 points, which is provisional until they have completed ten test matches. When countries merge, the new country inherits the higher rating of the two countries but when they split e.g., the 2010 breakup of the Arabian Gulf rugby union team into separate teams representing its current member countries, the new countries will inherit a rating at a fixed level below the rating of the original country.

Before 1 December 2012 new member nations were given 40.00 points.

Countries that have not played a test for two years are removed from the ranking system and the list. If they become active again, they resume their previous rating.
