The behavioural manifestations of trauma can be complex, challenging and emotionally demanding for prison staff. Due to the prevalence and pervasiveness of trauma within Her Majesty’s Prison Service (HMPS), it is important to view the experience of individuals in prison and those that work in prisons through a trauma-informed lens. Firstly, the reported prevalence of trauma within the prisoner population is considered. Secondly, this article examines the trauma-informed response from Her Majesty’s Prison and Probation Service (HMPS) from a theoretical, practical and policy perspective. In addition, this article highlights that by implementing a robust trauma informed approach within prisons, this can be beneficial for every individual working and living in prison. Some of the key challenges associated with the implementation of trauma-informed practice (TIP) and institutional transformation are presented in this article. In support of this, brief reflections from doctoral research examining the early implementation of TIP are presented. Finally, future directions are considered for individuals working with trauma and how institutions can evaluate their implementation journey and practice. The ‘Working with Trauma Quality Mark’ is introduced as a quality assurance model in order to develop trauma practice, whilst providing a mechanism to demonstrate and celebrate aspects of good practice across HMPS.
