Huw Lloyd, head teacher at Ebbw Fawr Learning Community in Ebbw Vale, said by giving schools like his information quickly, teachers and school staff are ready to support children.
"We get the phone calls in the morning, from a designated person from the police who contacts a designated person within the school if the police have been called to an incident of domestic abuse and the child is within our school," he said.
This is reported where schools may not receive the information as late as 3 weeks beyond the initial incident where it is felt to be either resolved or too late for them to intervene with the damage already being done to the children.
Pupils can be offered a quiet space for them, some breakfast and the chance to speak to a member of staff or a specially trained counselor or social worker. They can then talk about what events has happened in the last 24 hours.
Public health wales full support is gone into this and is about to launch a TV advert campaign to bring awareness of the impact of ACEs.
