Learning Together is the largest school intervention targeting bullying and aggression delivered in the UK. It involved 40 secondary schools with over 6500 students over 3 years. The intervention involved restorative practice, action groups and a student curriculum on relationships and emotions. The results were extremely promising, with pupils in the intervention schools reporting significantly lower levels of bullying, better health and mental health at the end of the trial.
