Clarification regarding New Zealand's role on the Test ranking table was provided by the official Twitter handle of the ICC. This comes after many reports claimed that after their victory over Pakistan in the recently completed test, New Zealand had become the top-ranked Test team in the world.
For every test match played, the ICC rating system is focused on allocating points to teams and then averaging them overall tests played by the team during the time under consideration. For the team during that time, the final rating is an average ranking.
The points awarded to a team are based on the opposition's power. A victory against a more vigorous opposition counts more than a win against a weaker side for more points. At the beginning of the series, their rating points decide the power of the resistance.
It should be remembered that changes only occur at the end of a series, not after each test match. The victory of a series counts as an additional Test match won. Therefore, if a team wins a series 2-1, it will count as a 3-1 victory when points are awarded.
For a Test win, each team gets one point, 0.5 points for a draw, and an extra point for success in a series. Thus, if New Zealand wins 2-0 against Pakistan in the two-test series, they will get 3 points, while Pakistan will get 0.0. If the series draw 1-1, each of the teams earns a point for their respective match wins, and no points for the series.
