This document outlines the UK film rating system established by the British Board of Film Classification (BBFC). It describes the seven different age ratings used to restrict viewing of films based on content like violence, language, sex, drugs and more. Ratings include U for all ages, PG for parental guidance for ages 8+, 12A for ages 12+ accompanied by an adult, 15 for ages 15+, and 18 for adults only due to very strong content. The document concludes that a new film about bullying with some psychological aspects would likely receive a PG or 12A rating to allow broader audience access.
