Barnardo's, the leading children's charity, has called on schools to do even more to combat the root causes of poor behaviour.

The charity observed that badly behaved kids often may have special needs or personal problems, which may lead them to behave in a way that is disruptive to their fellow classmates.

"A school teacher's job is not an easy one, but they must look behind the behaviour to see the child. Unruly pupils may be acting out, not just acting up," explained Barnardo's chief executive Anne Marie Carrie.

"The most 'out of control' children may be the most vulnerable children facing horrendous problems at home."

In terms of children with special needs, Ms Carrie said that these problems need to be identified at the earliest moment in order to give children the best chance of succeeding.

Education and a stable family life, she said, are critical if children are to overcome such issues and thrive in later life.
