- Themes- Where more serious issues are featured (e.g. Racism) nothing in their treatment should condone the behaviour.
- Language- Mild bad language only.
- Nudity- Natural nudity only.
- Sex- Sexual activity may be implied but must be discrete.
- Violence- Moderate violence may be shown if justified by the setting.
- Horror- Freighting sequences must not be prolonged or intense.
- Drugs- Any references to drugs or drug misuse must be innocuous or carry a suitable anti-drug message.
According to BBFC rating schemes a film with a 12 rating must match this criterion:
- Themes- Mature themes are acceptable, but their treatment must be suitable for young teenagers.
- Language- The use of strong language must be infrequent. Racist abuse is also of particular concern.
- Nudity- Nudity is allowed but in sexual context, must be discrete and brief.
- Sex- Sexual activity may be implied. Sex references may reflect what is likely to be familiar to most adolescents but should not go beyond what is suitable for them.
- Violence- Violence must not dwell on detail. There should be no emphasis on injuries or blood. Sexual violence may only be implied or briefly and discreetly indicated.
- Horror- Sustained moderate threat and menace are permitted. Occasionally gory moments only.
- Drugs- Any misuse of drugs must be infrequent and should not be glamorized or instructional.
According to BBFC rating schemes a film with a 15 rating must match this criterion:
- Theme- No theme is prohibited, provided the treatment is appropriate to 15 year olds.
- Language- There may be frequent use of strong language (e.g. 'fuck'). But the strongest terms (e.g. 'c*nt') will be acceptable only where justified by the context. Continued aggressive use of the strongest language is unlikely to be acceptable.
- Nudity- Nudity may be allowed in a sexual context but without strong detail. There are no constraints on nudity in a non-sexual or educational context.
- Sex- Sexual activity may be portrayed but without strong detail. There may be strong verbal references to sexual behaviour.
- Violence- Violence may be strong but may not dwell on the infliction of pain or injury. Scenes of sexual violence must be discreet and brief.
- Horror- Strong threat and menace are permitted. The strongest gory images are unlikely to be acceptable.
- Drugs- Drug taking may be shown but the film as a whole must not promote or encourage drug misuse.
According to BBFC's rating schemes there is no real criteria '18' has to be matched up to as adults should be allowed to know for themselves what it funny, and what they find entertaining.
