# FIVB Senior World Rankings

The FIVB Senior World Rankings is a ranking system for men's and women's national teams in volleyball. 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 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 23 July 2023, the highest ranked team in the men's category is Poland, while in the women's category is Turkey.

## 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 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 or FIFA World ranking, where, after each game, points will be added to or subtracted from a team's rating according to the formula:
    $S_{\text{after}}=S_{\text{before}}+{K(R-E) \over 8}$
where:
* $S_{\text{after}}$ – the team's number of World Ranking scores after the game
* $S_{\text{before}}$ – 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); see below
* $E$ – 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; see below for calculation details.

#### Expected match result

The expected results is then calculated as $E=R_{1}P_{1}+R_{2}P_{2}+R_{3}P_{3}+R_{4}P_{4}+R_{5}P_{5}+R_{6}P_{6}$ where $P_{n}$ is the probability of the outcome $R_{n}$ obtained using the following model (known as Ordered probit):

##### Team A win 3–0

    $P_{\text{1}}=\Phi (C_{\text{1}}+\Delta )$

##### Team A win 3–1

    $P_{\text{2}}=\Phi (C_{\text{2}}+\Delta )-\Phi (C_{\text{1}}+\Delta )$

##### Team A win 3–2

    $P_{\text{3}}=\Phi (C_{\text{3}}+\Delta )-\Phi (C_{\text{2}}+\Delta )$

##### Team A lose 2–3

    $P_{\text{4}}=\Phi (C_{\text{4}}+\Delta )-\Phi (C_{\text{3}}+\Delta )$

##### Team A lose 1–3

    $P_{\text{5}}=\Phi (C_{\text{5}}+\Delta )-\Phi (C_{\text{4}}+\Delta )$

##### Team A lose 0–3

    $P_{\text{6}}=1-\Phi (C_{\text{5}}+\Delta )$
where $\Phi (z)$ is the Cumulative distribution function of the Normal distribution, and $C_{1},\ldots ,C_{5}$ are the cut-points
* $C_{1}=-1.06$
* $C_{2}=-0.394$
* $C_{3}=0$
* $C_{4}=0.394$
* $C_{5}=1.06$
set so that $P_{n}$ is the probability of the outcome $n$ between two equal strength opponents (that is when $\Delta =0$), which is derived from the actual match results of the past decade.
The parameter $\Delta$ represents the scaled difference of the teams rankings
    $\Delta ={8(S_{\text{teamA}}-S_{\text{teamB}}) \over 1000}$
where:
* $S_{\text{teamA}}$ – the team A's number of World Ranking scores before the game
* $S_{\text{teamB}}$ – the team B's number of World Ranking scores before the game

### Examples

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

    $\Delta ={8(415-192) \over 1000}=1.784$

#### Expected match result

* $P_{1}=\Phi (-1.060+1.784)$
* $P_{2}=\Phi (-0.364+1.784)-\Phi (-1.060+1.784)$
* $P_{3}=\Phi (0.000+1.784)-\Phi (-0.364+1.784)$
* $P_{4}=\Phi (0.364+1.784)-\Phi (0.000+1.784)$
* $P_{5}=\Phi (1.060+1.784)-\Phi (0.364+1.784)$
* $P_{6}=1-\Phi (1.060+1.784)$
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 and Continental Rankings

The five Continental Rankings filter the World Ranking points won and lost in matches played between teams from the same Continental Confederation.
* Intercontinental Tournaments – calculated in World Rankings, but some matches can be calculated in Continental Rankings
** Olympic Games final and intercontinental qualification tournaments
** FIVB World Championship final and intercontinental qualification tournaments
** FIVB World Cup
** FIVB Volleyball Nations League and Challenger Cup
** some Continental Cups: Pan-America
** some FIVB recognised international events, e.g. Pan American Games, Montreux Volley Masters
* Continental Tournaments – calculated in World and Continental Rankings
** Olympic Games continental qualification tournaments
** FIVB World Championship continental qualification tournaments
** FIVB Challenger Cup qualification tournaments
** Continental Championships: Asia (AVC), Africa (CAVB), Europe (CEV), North America (NORCECA), and South America (CSV)
** some Continental Cups: Asia (both AVC Cup and Challenge Cup)
** Zonal Championships, e.g. Eastern Asia, ASEAN, Central America
** some FIVB recognised international events, e.g. African Games, Asian Games, European Games
