Victorian police called to family violence incidents will use a scorecard to figure out if violence is likely to occur again in the future.
The new tool in the fight against family violence will help frontline officers intervene and help victims by generating a score out of 15 to determine the likelihood of future violence.
The higher the score, the higher the chances.
"Put simply, we had to change, we had to listen and we've done that," Family Violence Command Assistant Commissioner Dean McWhirter told reporters.
"It's not about a fast response, it's about an informed response, it's actually about members asking questions and eliciting information that actually will determine the level of risk and trauma."
Family violence and violence against women was core police work, accounting for approximately 40 to 60 per cent of frontline police time, he said.
The new reporting system will give officers consistent information and more guidance to understand the intricacies of relationships and risk levels.
Developed with Swinburne University and Forensicare, the Family Violence Report was trialled for two years and will be rolled out across Victoria on Wednesday.
"Today is about making sure every single frontline police officer, who spends many hours every single day supporting women and children who are victims of family violence, have the right tools at their fingertips to make the best possible decision about how we can keep these victims safe," Police Minister Lisa Neville said.
