FEI is a college football rating system based on opponent-adjusted drive efficiency. Approximately 20,000 possessions are contested annually in FBS vs. FBS games. First-half clock-kills and end-of-game garbage drives and scores are filtered out. Defensive Efficiency (DE) is the value generated per drive a team's opponent offenses adjusted for starting field position. DFEI is defensive efficiency adjusted for the strength of opponent offenses faced.

Defensive Drive Success rate (DDS) is the percentage of opponent offensive drives that generate value greater than the starting field position value of the drive. Available Yards percentage (DAY) is the total number of yards surrendered by the defense divided by the number of yards available to be earned based on starting field position. First Down Rate (DFD) is the percentage of opponent offensive drives that result in a touchdown or at least one first down. Touchdown Rate (DTD) is the percentage of opponent offensive drives that result in a touchdown. Touchdown Rate After First Down (DTF) is the percentage touchdowns surrendered on opponent offensive drives that earn at least one first down. Turnover Rate (DTO) is the percentage of opponent offensive drives that result in a fumble or interception.
