College football rankings, explained: How the AP Top 25 poll works

A look at how the AP Top 25 college football rankings are made

College football rankings are always a matter of intense debate, and a lot of disagreement. How can they not be? A team's place in the AP Top 25 poll, and certainly the College Football Playoff rankings, is crucial to judging the success or failure of a season.

Since 1936, the AP poll has been key in deciding which teams are in the race for the national championship. Then in 1998, the BCS computer model supplanted it as the most important metric. And then in 2014, the College Football Playoff system replaced that, introducing an on-field semifinal format.

But that doesn't mean the AP poll has been relegated to the museums just yet. It's still vital in setting the tone for the argument over much of the season, and helps directly influence the CFP rankings, too.

How is the AP Top 25 poll created? Let's take a look at how the process works.

College football rankings explained: How the AP Top 25 poll is made

Beginning in late August with the annual preseason poll, the AP ranks the 25 best teams in college football every week during the season. It also releases a poll after the bowl season and College Football Playoff.

More than 60 sports writers and broadcasters across the country cast their votes individually. The AP selects the voters by virtue of their experience covering the sport.

Voters first create a list of what they consider the 25 best teams in the country. From there, they assign each team a number of points, awarding the best team the most number of points, which is 25. They give the second-lowest number to the second-best team, the third-lowest to the third-best team, etc.

• No. 1 team: 25 points
• No. 2 team: 24
• No. 3 team: 23
• No. 4 team: 22
• No. 5 team: 21
• No. 6 team: 20
• No. 7 team: 19
• No. 8 team: 18
• No. 9 team: 17
• No. 10 team: 16
• No. 11 team: 15
• No. 12 team: 14
• No. 13 team: 13
• No. 14 team: 12
• No. 15 team: 11
• No. 16 team: 10
• No. 17 team: 9
• No. 18 team: 8
• No. 19 team: 7
• No. 20 team: 6
• No. 21 team: 5
• No. 22 team: 4
• No. 23 team: 3
• No. 24 team: 2
• No. 25 team: 1

The AP then combines the numerical value of each voter's poll and ranks the teams by number of points in descending order to create the final rankings.

AP Top 25 poll history

The AP first unveiled a college football poll back in 1934, but the following season resulted in a three-way tie for the national championship.

That inspired the organization to create a new poll consisting of sports editors, and that's the poll we've seen released every week since 1936.

From 1936 to 1960, the AP ranked 20 teams each week, and from 1961 to 1967 it ranked just the Top 10. It went back to 20 teams for the next 20 years, and expanded to the Top 25 starting in 1989.

Minnesota topped the first-ever AP poll in 1936, followed by No. 2 Duke, No. 3 Army, and No. 4 Northwestern. 

The 7-1 Gophers finished that season as national champions at No. 1 while LSU ranked No. 2, Pittsburgh at No. 3, and Alabama at No. 4.

The AP revealed the first-ever preseason Top 25 rankings ahead of the 1950 NCAA season. Notre Dame led that poll, followed by No. 2 Army, No. 3 Michigan, No. 4 Tennessee, and No. 5 Texas. Oklahoma, ranked No. 6 that preseason, won the national championship.
