Mental health disorders are emotional and behavioural problems that are not typical for a child’s age or gender.
The problem will be particularly severe or persistent over time, or the child will experience multiple problems at the same time.
Do not try to diagnose a mental health condition – only medical professionals should do this.
If you’re worried about a child, speak to your DSL (deputy DSL) and follow the school’s procedures for reporting safeguarding concerns.
