The AP Top 25 is determined by a simple points system based on how each voter ranks college football's best teams. A team receives 25 points for each first place vote, 24 for second place and so on through to the 25th team, which receives one point. The rankings are set by listing the teams' point totals from highest to lowest.
The mathematical formula is the same as the one used for the AP Pro 32 rankings and the AP Top 25 rankings for men's and women's basketball.
