1 by the Dickinson System in 1924, 1929, and 1930 and awarded the Rissman Trophy. Knute Rockne's teams gained permanent possession of this national championship trophy by winning it three times in ten years. Notre Dame has won eight wire service national championships awarded by the AP Poll and/or Coaches Poll, second most in the post–1936 poll era. The three Dickinson System and eight wire service national championships make a total of 11, but Notre Dame is often credited with additional national championships. The 1938, 1953, and 1964 seasons are part of the reason for the discrepancy. In the 1938 season, 8–1 Notre Dame was awarded the Knute Rockne Memorial Trophy and the national championship by the Dickinson System, while TCU (which finished 11–0) was awarded the championship by the Associated Press. In the 1953 season, an undefeated Notre Dame team (9–0–1) was named national champion by almost every major selector except the AP and UPI (coaches') polls, where the Irish is finished second in both to 10–1 Maryland. In 1964 Notre Dame was named national champions by the National Football Foundation and awarded the MacArthur Bowl. As Notre Dame has a policy of only recognizing AP and Coaches' Poll national championships post-1936, the school does not officially recognize the 1938, 1953, or 1964 national championships. Beyond their eleven claimed national championships, Notre Dame has been named national champion by at least one NCAA-designated "major selector" in an additional eleven seasons: 1919, 1920, 1927, 1938, 1953, 1964, 1967, 1970, 1989, 1993, and 2012. Notre Dame's 11 claimed national championships are: Following its appearance in the 1925 Rose Bowl, Notre Dame did not play in a post-season game for 44 consecutive years (1925–1968), including after many of the team's most successful seasons from the Rockne era in the 1920s and the Leahy era in the 1940s. The university's stated reasons for its self-imposed hiatus were that bowl games were “glorified exhibitions” that played no part in national championship selections and that they extended the season too far to the detriment of players' academic progress. Appearances in the final Associated Press Poll Notre Dame has made 715 appearances in the Associated Press poll over 71 seasons. Notre Dame has spent 496 weeks in the Top 10, 277 weeks in the Top 5, and 95 weeks at No. 1. Notre Dame has finished the year ranked in the final Associated Press poll of
