Only appropriately trained professionals should attempt to make a diagnosis of a mental health problem. Education staff, however, are well placed to observe children day-to-day and identify those whose behaviour suggests that they may be experiencing a mental health problem or be at risk of developing one. Schools and colleges can access a range of advice to help them identify children in need of extra mental health support, this includes working with external agencies. 45. If staff have a mental health concern about a child that is also a safeguarding concern, immediate action should be taken to follow their school or college’s child protection policy and by speaking to the designated safeguarding lead or a deputy. Serious violence 46. All staff should be aware of the indicators, which may signal children are at risk from, or are involved with, serious violent crime. These may include increased absence from school or college, a change in friendships or relationships with older individuals or groups, a significant decline in educational performance, signs of self- harm or a significant change in wellbeing, or signs of assault or unexplained injuries. Unexplained gifts or new possessions could also indicate that children have been approached by, or are involved with, individuals associated with criminal networks or gangs and may be at risk of criminal exploitation.
