Rank (Halo 4)

There are two ranking systems in Halo 4: Spartan Rank, a progression ranking system, and Competitive Skill Rank, a skill ranking system.

Spartan Rank (SR)
A player's Spartan Rank is displayed on his player card. Players start at SR-1 and rank up by earning XP through completing War Games matches, Spartan Ops matches, Commendations, and Challenges. Once a player reaches SR-50, he must choose a Specialization in order to continue ranking up. Each Specialization accounts for 10 additional ranks. After all 8 Specializations have been completed, the player will have reached the maximum rank of SR-130.

Note: When a player chooses a Specialization, his rank immediately increases (for example, from SR-50 to SR-51).

Competitive Skill Rank (CSR)
Competitive Skill Rank measures a player's skill in a playlist on a scale of 1 to 50. Players start at 1 and rank up or down depending on their performance and rank relative to other players in the match. It was implemented on April 8, 2013, and is only visible on Halo Waypoint.


 * CSR is always a game behind. That means that after every game, CSR is updated with the effects from the game before it.
 * Players who join a game in progress are treated as if they played the entire match.
 * Although 343i has officially stated that leaving a match before it's finished counts the player as having lost in team-based CSR playlists and being the lowest-scoring player in individual CSR playlists, quitting a match does not appear to affect CSR at all.
 * Players can view the CSRs of the players they played against by going to their Game History in their Halo 4 Stats on Halo Waypoint.

Team-based CSR
Team-based CSR judges players based strictly on whether they won or lost regardless of individual performance such as kills or score. Players will rank up if they consistently win against teams of players who are ranked the same or higher than they are.

Playlists that use team-based CSR typically focus on teamwork, such as Team Slayer, Capture the Flag, and Proving Ground.

Individual CSR
Individual CSR judges players based strictly on their score regardless of whether their team won or lost. Players will rank up if they consistently score higher than players who are ranked the same or higher than they are.

Playlists that use individual CSR typically focus on individual skill, such as Rumble Pit, Team Snipers, and Big Team Battle.
