<P> The Coaches' poll began selecting the top 20 teams on a weekly basis during the 1950--1951 college football season . It is conducted among selected members of the American Football Coaches Association . In 1990 the poll expanded to a top 25, and it has retained this format since . The Coaches' Poll took their final poll prior to the bowl games from 1950--1973, and since 1974, has taken their final poll after bowl games . The Coaches' Poll does not include teams on either NCAA or conference - sanction probation, which also differentiates it from the AP poll . The poll has been released through various media outlets and with differing sponsors over its history, and thus has taken a succession of different names, including United Press (UP) from 1950 thru 1957, the United Press International (UPI) from 1958 thru 1990, USA Today / CNN from 1991 thru 1996, USA Today / ESPN from 1997 to 2004, and USA Today from 2005 to present . </P> <P> During the era of the BCS, the Coaches' Poll was under contractual obligation to award its national championship selection to the winner of the BCS Championship Game or its predecessors--who was presented with the AFCA National Championship Trophy during a post-game presentation . The College Football Playoff is not tied to the Coaches' Poll in this manner . </P> <P> The following table contains the National Championships that have been recognized by the final AP or Coaches' Poll . Originally both the AP and Coaches' poll champions were crowned after the regular season, but since 1968 and 1974, respectively, both polls crown their champions after the bowl games are completed . The BCS champion was automatically awarded the Coaches' Poll championship . Of the current 120 + Football Bowl Subdivision (FBS, formerly Division I-A) schools, only 30 have won at least a share of a national title by the AP or Coaches' poll . Of these 30 teams, only 19 teams have won multiple titles . Of the 19 teams, only 7 have won five or more national titles: Alabama, Notre Dame, Oklahoma, USC, Miami (FL), Nebraska, and Ohio State . The years listed in the table below indicate a national championship selection by the AP or Coaches' Poll . The selections are noted with (AP) or (Coaches) when a national champion selection differed between the two polls for that particular season, which has occurred in twelve different seasons (including 2004, for which the coaches selection was rescinded) since the polls first came to coexist in 1950 . </P> <Table> <Tr> <Th> School </Th> <Th> Championships </Th> <Th> Seasons </Th> </Tr> <Tr> <Td> Alabama </Td> <Td> 11 </Td> <Td> 1961, 1964, 1965 (AP), 1973 (Coaches), 1978 (AP), 1979, 1992, 2009, 2011, 2012, 2015 </Td> </Tr> <Tr> <Td> Notre Dame </Td> <Td> 8 </Td> <Td> 1943, 1946, 1947, 1949, 1966, 1973 (AP), 1977, 1988 </Td> </Tr> <Tr> <Td> Oklahoma </Td> <Td> 7 </Td> <Td> 1950, 1955, 1956, 1974 (AP), 1975, 1985, 2000 </Td> </Tr> <Tr> <Td> USC </Td> <Td> 7 </Td> <Td> 1962, 1967, 1972, 1974 (Coaches), 1978 (Coaches), 2003 (AP), 2004 (AP) * </Td> </Tr> <Tr> <Td> Ohio State </Td> <Td> 6 </Td> <Td> 1942, 1954 (AP), 1957 (Coaches), 1968, 2002, 2014 </Td> </Tr> <Tr> <Td> Miami (FL) </Td> <Td> 5 </Td> <Td> 1983, 1987, 1989, 1991 (AP), 2001 </Td> </Tr> <Tr> <Td> Nebraska </Td> <Td> 5 </Td> <Td> 1970 (AP), 1971, 1994, 1995, 1997 (Coaches) </Td> </Tr> <Tr> <Td> Minnesota </Td> <Td> </Td> <Td> 1936, 1940, 1941, 1960 </Td> </Tr> <Tr> <Td> Texas </Td> <Td> </Td> <Td> 1963, 1969, 1970 (Coaches), 2005 </Td> </Tr> <Tr> <Td> Florida </Td> <Td> </Td> <Td> 1996, 2006, 2008 </Td> </Tr> <Tr> <Td> Florida State </Td> <Td> </Td> <Td> 1993, 1999, 2013 </Td> </Tr> <Tr> <Td> LSU </Td> <Td> </Td> <Td> 1958, 2003 (Coaches), 2007 </Td> </Tr> <Tr> <Td> Army </Td> <Td> </Td> <Td> 1944, 1945 (AP) </Td> </Tr> <Tr> <Td> Auburn </Td> <Td> </Td> <Td> 1957 (AP), 2010 </Td> </Tr> <Tr> <Td> Clemson </Td> <Td> </Td> <Td> 1981, 2016 </Td> </Tr> <Tr> <Td> Michigan </Td> <Td> </Td> <Td> 1948, 1997 (AP) </Td> </Tr> <Tr> <Td> Michigan State </Td> <Td> </Td> <Td> 1952, 1965 (Coaches) </Td> </Tr> <Tr> <Td> Penn State </Td> <Td> </Td> <Td> 1982, 1986 </Td> </Tr> <Tr> <Td> Pittsburgh </Td> <Td> </Td> <Td> 1937, 1976 </Td> </Tr> <Tr> <Td> Tennessee </Td> <Td> </Td> <Td> 1951, 1998 </Td> </Tr> <Tr> <Td> BYU </Td> <Td> </Td> <Td> 1984 </Td> </Tr> <Tr> <Td> Colorado </Td> <Td> </Td> <Td> 1990 (AP) </Td> </Tr> <Tr> <Td> Georgia </Td> <Td> </Td> <Td> 1980 </Td> </Tr> <Tr> <Td> Georgia Tech </Td> <Td> </Td> <Td> 1990 (Coaches) </Td> </Tr> <Tr> <Td> Maryland </Td> <Td> </Td> <Td> 1953 </Td> </Tr> <Tr> <Td> Oklahoma State </Td> <Td> </Td> <Td> 1945 (Coaches) * * </Td> </Tr> <Tr> <Td> Syracuse </Td> <Td> </Td> <Td> 1959 </Td> </Tr> <Tr> <Td> TCU </Td> <Td> </Td> <Td> 1938 </Td> </Tr> <Tr> <Td> Texas A&M </Td> <Td> </Td> <Td> 1939 </Td> </Tr> <Tr> <Td> UCLA </Td> <Td> </Td> <Td> 1954 (Coaches) </Td> </Tr> <Tr> <Td> Washington </Td> <Td> </Td> <Td> 1991 (Coaches) </Td> </Tr> </Table>
