The FIVB Senior World Rankings is a ranking system for men's and women's national teams in
volleyball Volleyball is a team sport in which two teams of six players are separated by a net. Each team tries to score points by grounding a ball on the other team's court under organized rules. It has been a part of the official program of the Summ ...
. The teams of the member nations of Fédération Internationale de Volleyball (FIVB), volleyball's world governing body, are ranked based on their game results with the most successful teams being ranked highest. A points system is used, with points being awarded based on the results of all FIVB-recognised full international matches. The rankings are used in international competitions to define the seeded teams and arrange them in pools. Specific procedures for seeding and pooling are established by the FIVB in each competition's formula, but the method usually employed is the
serpentine system The serpentine system (also called snake seeding) is a method employed in the organization of a competition to define the seeded teams and arrange them in pools. The ''n'' ranked teams that will be involved in the tournament are distributed in ''m ...
. The ranking system has been revamped in 2020, responding to criticism that the preceding calculation method did not effectively reflect the relative strengths of the national teams. The old version of the ranking system was finally used on 31 January 2020. As of 16 November 2022, the highest ranked team in the men's category is

Previous calculation method

The system of point attribution for the selected FIVB World and Official Competitions below is as follows: *Olympic Games and qualifying tournaments: included for 4 years and points are also granted for the qualification matches, to the best non-qualified teams. *World Championship and qualifying tournaments: included for 4 years and points are also granted for the qualification matches, to the best non-qualified teams. *World Cup: included for 4 years *World Grand Prix: included for 1 year *World League: included for 1 year


Current calculation method

In 2019, FIVB collaborated with Hypercube Business Innovation of the Netherlands to design a new world ranking platform. The previous calculation method had a problem of circularity in the international volleyball calendar: only countries who participate in the major volleyball events can earn ranking points, whilst the number of ranking points of countries also determines seeding and access of teams for major events. This unfair principle does not contribute to the sporting and commercial quality of volleyball. On 1 February 2020, the new ranking system will be implemented and will take into account all results from 1 January 2019. The system will be consistently updated to reflect the latest results and performances. The new World Ranking considers the match results from all official competitions: *
Olympic Games The modern Olympic Games or Olympics (french: link=no, Jeux olympiques) are the leading international sporting events featuring summer and winter sports competitions in which thousands of athletes from around the world participate in a var ...
and qualifying tournaments * FIVB World Championship * FIVB World Cup *FIVB Nations League and Challenger Cup *Confederations' Championship and qualifying tournaments *Other annual official events organized by Continental Confederations. The rankings outcome of each match depends on two main factors: *The playing strength of the teams competing *The actual match performance or final result of the match


Ranking Procedure

It is based on the zero-sum system, like
CONCACAF Ranking Index The Confederation of North, Central America and Caribbean Association Football,, ; french: Confédération de football d'Amérique du Nord, d'Amérique centrale et des Caraïbes, . Dutch uses the English name. abbreviated as CONCACAF ( ; typese ...
, and after each game points will be added to or subtracted from a team's rating according to the formula: :S_\text = S_\text + where: *S_\text – the team's number of ''World Ranking scores'' after the game *S_\text – the team's number of ''World Ranking scores'' before the game *K – the match importance: ** 10.0 – Other annual official events organized by Continental Confederations ** 17.5 – Confederations' Championship qualifying ** 20.0 – FIVB Challenger Cup ** 35.0 – Olympic Games qualifying, FIVB World Cup and Confederations' Championship ** 40.0 – FIVB Nations League ** 45.0 – FIVB World Championship ** 50.0 – Olympic Games *R – the result of the game depended on match and sets won (3-0, 3-1, 3-2, 2-3, 1-3 or 0-3) *E – the expected result of the game has the value between -2 and +2. If the match is completely balanced, the expected result is 0. The bigger the surprise, the more points are transferred.


Strength difference between the teams

: \Delta = where: *S_\text – the team A's number of ''World Ranking scores'' before the game *S_\text – the team B's number of ''World Ranking scores'' before the game


Probability of outcomes

;Team A win 3–0 : P_\text = \sim N(0,1)(C_\text+\Delta) ;Team A win 3–1 : P_\text = \sim N(0,1)(C_\text+\Delta) - \sim N(0,1)(C_\text+\Delta) ;Team A win 3–2 : P_\text = \sim N(0,1)(C_\text+\Delta) - \sim N(0,1)(C_\text+\Delta) ;Team A lose 2–3 : P_\text = \sim N(0,1)(C_\text+\Delta) - \sim N(0,1)(C_\text+\Delta) ;Team A lose 1–3 : P_\text = \sim N(0,1)(C_\text+\Delta) - \sim N(0,1)(C_\text+\Delta) ;Team A lose 0–3 : P_\text = 1- \sim N(0,1)(C_\text+\Delta) where: * C_\text – the cut-points in the

Expected match result

Examples

There are the examples of the new ranking procedure. Before the match at the ''FIVB Volleyball World Championship (K = 45)'', Brazil ''(Team A)'' is ranked number 1 with a ''415 WR score'' and Japan ''(Team B)'' is ranked number 11 with a ''192 WR score''. ;Strength difference between Brazil and Japan : \Delta = = 1.784 ;Expected match result * C_\text = -1.060 * C_\text = -0.364 * C_\text = 0.000 * C_\text = 0.364 * C_\text = 1.060 *P_\text = \sim N(0,1)(-1.060+1.784) *P_\text = \sim N(0,1)(-0.364+1.784) - \sim N(0,1)(-1.060+1.784) *P_\text = \sim N(0,1)(0.000+1.784) - \sim N(0,1)(-0.364+1.784) *P_\text = \sim N(0,1)(0.364+1.784) - \sim N(0,1)(0.000+1.784) *P_\text = \sim N(0,1)(1.060+1.784) - \sim N(0,1)(0.364+1.784) *P_\text = 1 - \sim N(0,1)(1.060+1.784) Expected match result for Brazil: : E = 76.5%(+2) + 15.2%(+1.5) + 4.5%(+1) + 2.2%(-1) + 1.2%(-1.5) + 0.2%(-2) = +1.76 Expected match result for Japan: : E = 0.2%(+2) + 1.2%(+1.5) + 2.2%(+1) + 4.5%(-1) + 15.2%(-1.5) + 76.5%(-2) = -1.76 ;World Ranking scores after Brazil win 3–0 World Ranking scores for Brazil: :S_\text = \text + = 416.35 World Ranking scores for Japan: :S_\text = \text + = 190.65 ;World Ranking scores after Brazil win 3–1 World Ranking scores for Brazil: :S_\text = \text + = 413.54 World Ranking scores for Japan: :S_\text = \text + = 193.46 ;World Ranking scores after Brazil win 3–2 World Ranking scores for Brazil: :S_\text = \text + = 410.73 World Ranking scores for Japan: :S_\text = \text + = 196.27 ;World Ranking scores after Brazil lose 0–3 World Ranking scores for Brazil: :S_\text = \text + = 393.85 World Ranking scores for Japan: :S_\text = \text + = 213.15 ;World Ranking scores after Brazil lose 1–3 World Ranking scores for Brazil: :S_\text = \text + = 396.66 World Ranking scores for Japan: :S_\text = \text + = 210.34 ;World Ranking scores after Brazil lose 2–3 World Ranking scores for Brazil: :S_\text = \text + = 399.48 World Ranking scores for Japan: :S_\text = \text + = 207.52
