Technology Rating is a code used in the Classic BattleTech game indicating the relative sophistication of a piece of vehicles, 'Mech and other equipment, or of the subsystems found in the same. Its primary function is to determine what systems were available in a particular time period in the BattleTech universe. A similar system was used in the MechWarrior, First Edition roleplaying game. That scale was different, primarily because the Clans had not been developed when that game had been written.
