Hope that helps.
What is the legal position of a teacher who wants to show pupils a film or video at a higher category than their age?
The BBFC's cinema age ratings only apply legally to licensed cinemas, so it is not illegal for schools to show BBFC-rated videos or DVDs to its pupils of any age. Merely showing an age restricted tape to underaged persons - or allowing them to see one - is not in itself an offence. We would however strongly discourage such a practice unless (a), the children in question are only a year or so below the age stated on the certificate, and (b), there is some kind of serious educational purpose to showing the recording (eg showing a 15 rated Macbeth to 14 year old GCSE English students). Even in those cases, we always recommend that the school should obtain permission from parents or guardians.
Hope that helps.
