The "Parental Advisory Label Program" in the United States and the "Parental Advisory Scheme" in the United Kingdom lack agreed-upon standards for using the warning label, although they provide guidelines for its recommended inclusion. Although a voluntary practice that is ultimately left to the discretion of record labels, the RIAA suggests that material with "strong language or depictions of violence, sex, or substance abuse to such an extent as to merit parental notification" be affixed with the Parental Advisory label. The BPI additionally requests that "racist, homophobic, misogynistic or other discriminatory language or behavior" be taken under consideration when determining the appropriateness of a record.
