A child who has been bullied learns something about whether the world is safe enough for their voice. That lesson does not disappear when the bullying stops.

There is a phrase that has been used to dismiss bullying for generations, and it does enormous damage every time it is said. "It's just a part of growing up." It is not. The evidence on this is now unambiguous, and in 2024 the University of York published research calling formally for bullying to be recognised as a traumatic experience and treated accordingly.

One in four children in the UK are currently experiencing bullying. Twenty-one per cent of secondary pupils reported being bullied in the past year, with rates highest among younger adolescents. Children who are bullied are significantly more likely to experience poor wellbeing, lower life satisfaction, and internalising mental health difficulties including anxiety and depression.

Those bullied in early childhood are up to three times more likely to self-harm in adolescence. The effects persist into adulthood. They shape what children come to believe about themselves, about whether they are worth defending, about whether the adults around them can be trusted to act.

The structural inequality in these figures deserves naming. Children receiving Free School Meals are more likely to be bullied. Children with SEND are nearly three times more likely. Eighty-three per cent of young people with learning difficulties report having experienced bullying. The children with the least power are, predictably, the most targeted.

And the institutional response is not keeping pace with the scale of the problem. University of York research found that only 22% of parents who reported their child's bullying to school said the situation had improved as a result. The UK sits above the OECD average for bullying rates among 15-year-olds. Thirty-one children per day are currently contacting crisis services about it.

Recognising bullying as trauma is not a rhetorical shift. It has practical implications. Trauma-informed responses start with believing the child. They prioritise stabilising the child's sense of safety and belonging before attempting to address the behaviour of the perpetrator. They involve the family. They do not treat the bullied child as a complaint to be assessed.

Every child deserves to know that their account of their own experience will be taken seriously by the adults responsible for their care. That is not a high bar. It is the floor.
