Who votes in the poll, and how does it work?

No organization has been ranking teams and naming a major college football national champion longer than The Associated Press, since 1936.

AP employees don’t vote themselves, but they do choose the voters. AP Top 25 voters comprise around 60 writers and broadcasters who cover college football for AP members and other select outlets. The goal is to have every state with a Football Bowl Subdivision school represented by at least one voter.

There is a 1-to-25 point system, with a team voted No. 1 receiving 25 points down to 1 point for a 25th-place vote. After that, it’s simple: The poll lists the teams with the most points from 1 to 25, and others receiving votes are also noted.

Voting is done online, and the tabulation is automated.
