Motion Picture Association film rating system

The Motion Picture Association film rating system is used in the United States and its territories to rate a motion picture's suitability for certain audiences based on its content. The system and the ratings applied to individual motion pictures are the responsibility of the Motion Picture Association (MPA), previously known as the Motion Picture Association of America (MPAA) from 1945 to 2019. The MPA rating system is a voluntary scheme that is not enforced by law; films can be exhibited without a rating, although most theaters refuse to exhibit non-rated or NC-17 rated films. Non-members of the MPA may also submit films for rating.^[1] Other media, such as television programs, music and video games, are rated by other entities such as the TV Parental Guidelines, the RIAA and the ESRB, respectively.

In effect as of November 1968,^[2] following the Hays Code of the classical Hollywood cinema era, the MPA rating system is one of various motion picture rating systems that are used to help parents decide what films are appropriate for their children. It is administered by the Classification & Ratings Administration (CARA), an independent division of the MPA.^[3]
