The Content Rating Scale
The RATED BOOKS reports reflect familiar rating systems used for movies, television, video games, and music, which help families identify levels of explicit content, language, profanity, violence, and other mature themes. These mainstream systems were modeled after the widely recognized MPA film rating system introduced in 1968.

The National Book Rating Index (NBRI) is a multi-source review platform that combines evaluations from independent reviewers to create a single national rating for each book. These ratings help highlight content concerns such as language, violence, sexual themes, and ideological content, giving parents and educators a clearer understanding of how a book’s material may impact its overall rating.
The NBRI is well suited for parent use, school and district use. Check out the GREENLIGHT TAB as well.
