| NCAA Division I FBS football rankings | |
Two human polls and a committee's selections comprised the2015National Collegiate Athletic Association (NCAA)Division IFootball Bowl Subdivision (FBS) football rankings, in addition to various publications' preseason polls. Unlike most sports, college football's governing body, the NCAA, does not bestow anational championship, instead that title is bestowed by one or more different polling agencies. There are two main weekly polls that begin in the preseason—theAP Poll and theCoaches Poll. One additional poll is released midway through the season; theCollege Football Playoff (CFP) rankings are released after the eighth week.
This was the second season of the four-team College Football Playoff system which replaced the previousBowl Championship Series system. At the conclusion of the regular season, on Sunday, December 6, 2015, the final CFP rankings will determine who will play in the twobowl games designated as semifinals for the2016 College Football Playoff National Championship on January 11, 2016, atUniversity of Phoenix Stadium inPhoenix, Arizona.
