The Grand Commendation system, introduced in patch 5.1.0, allows players to boost reputation gains for all characters on their account with certain Pandaria factions.

Each Grand Commendation is bought for a small sum of gold from the corresponding faction quartermaster. It is a heirloom quality item that must be used after purchase to take effect. Simply having a Grand Commendation in one's bag does nothing.

Faction Grand Commendation
Anglers  [Grand Commendation of the Anglers]
August Celestials  [Grand Commendation of the August Celestials]
Dominance Offensive  [Grand Commendation of the Dominance Offensive][1]
Golden Lotus  [Grand Commendation of the Golden Lotus]
Kirin Tor Offensive  [Grand Commendation of the Kirin Tor Offensive][2]
Klaxxi  [Grand Commendation of the Klaxxi]
Lorewalkers  [Grand Commendation of the Lorewalkers]
Operation: Shieldwall  [Grand Commendation of Operation: Shieldwall][1]
Order of the Cloud Serpent  [Grand Commendation of the Order of the Cloud Serpent]
Shado-Pan  [Grand Commendation of the Shado-Pan]
Sunreaver Onslaught  [Grand Commendation of the Sunreaver Onslaught][2]
Tillers  [Grand Commendation of the Tillers]

Grand Commendations are unlocked upon reaching revered reputation with the corresponding faction, and once used, double all reputation gains with that faction for all characters on the account, including the character who originally reached revered. This means that they effectively halve the reputation needed to reach exalted, making the climb from revered to exalted a little shorter (effectively 21,000/2 = 10,500 points) than from honored to revered (12,000 points).

The Dominance Offensive and Operation: Shieldwall reputation bonuses are linked, unlocking one unlocks both. This is also the case for the Kirin Tor Offensive and Sunreaver Onslaught.
