In recent years demand for policing in the UK has increased for occurrences relating to complex welfare, public safety and vulnerability. Research on the response to vulnerability by South Wales Police (SWP) identified a need for staff to be trained to understand the impact of Adverse Childhood Experiences (ACEs) and trauma to ensure that they have the right skills to assist vulnerable individuals in times of crisis and need. In response to these findings, the ACE-Informed Approach to Policing Vulnerability Training (AIAPVT) was developed. This report captures the independent evaluation of the training.
