Three human polls and one formulaic ranking make up the 2005 NCAA Division I-A football rankings, in addition to various publications' preseason polls. Unlike most sports, college football's governing body, the National Collegiate Athletic Association (NCAA), does not bestow a National Championship title for Division I-A football. That title is bestowed by different polling agencies. There are several polls that currently exist. The main weekly polls are the AP Poll and Coaches' Poll. About halfway through the season, two additional polls are released; the Bowl Championship Series (BCS) Rankings and the Harris Interactive Poll.
