Children who are socially left out at school may face much worse outcomes by the time they reach 18, according to new research. The study found that pupils who were sidelined in everyday school life were up to twice as likely to be jobless and not in education or training in late adolescence.

The findings point to common signs of exclusion, such as sitting alone during break times or regularly missing out when classmates choose teams and activities. Researchers linked those experiences with weaker prospects later on, suggesting that social isolation at school can be more than a short-term playground problem.

While the study does not mean every child who struggles socially will face the same future, it highlights a strong association between being excluded by peers and poorer early career or education outcomes. It adds to wider concerns about how belonging, confidence and participation at school can shape life beyond the classroom.

The research is likely to increase attention on children who appear detached during the school day, especially those who are overlooked rather than openly bullied. Its central message is that being left on the sidelines in childhood may have consequences that are still visible years later.
