Three human polls and one formulaic ranking make up the 2006 NCAA Division I FBS (Football Bowl Subdivision) football rankings, in addition to various publications' preseason polls.
Unlike most sports, college football's governing body, the NCAA, does not bestow a National Championship title.
About halfway through the season, two additional polls are released, the Harris Interactive Poll and the Bowl Championship Series (BCS) standings.
Jim Tressel, head coach of the Ohio State Buckeyes, refused to vote in the Week 15 poll, citing a conflict of interest.
In a change to the Coaches Poll for the 2006 season, the final ballots are made public.
