Scotland’s biggest teaching union is demanding better recording of violence in schools after it emerged councils could not provide conclusive data to show the extent of the incidents.

The Educational Institute of Scotland (EIS) said it has received reports of rising numbers of violent incidents.

However, the union claims teachers have been discouraged from reporting them.

Disturbing videos of violent fights between pupils have recently been highlighted in the media.

A video of two girls fighting at Waid Academy in Anstruther two weeks ago sparked the debate over violence and bullying in Scottish schools.

The film, widely shared on social media, showed a girl hitting the 14-year-old victim before pulling her to the floor, punching her on the arm, and kicking her on the head.

The Courier newspaper reported that a boy was knocked unconscious in a fight at the same school on the same day.

The head of the EIS told BBC Scotland she wants better recording of violence in schools because what is currently kept is incomplete.
