This technical report reviews the evidence on the effect of knife crime education interventions on the involvement of children and young people in crime and violence. This report is based primarily on a recent systematic review by Browne et al. (2022). Knife crime education interventions are implemented with children and young people in order to raise awareness of the legal implications of knife carrying as well as the physical and emotional implications. These interventions also aim to change attitudes about knife carrying and use in order to prevent and reduce the involvement of children and young people in crime and violence. Key components of these interventions include the delivery of educational sessions with groups of children and young people, the provision of workshops, and group discussions. Knife crime education interventions may adopt a ‘norms approach’, where the intervention content focuses on challenging children and young people’s perceptions that it is ‘normal’ to carry a knife. Other types of interventions to reduce knife crime, in particular media campaigns, have used real life stories to illustrate the profound impacts and consequences of carrying knives. For example, in 2017 the #knifefree campaign by the Home Office (2017) used stories from young people who had made the decision to not carry a knife. Knife crime education interventions would typically be implemented in settings where children and young people attend or gather, for example, schools or community centres. They could also be implemented in hospitals or Youth Offender Institutions. Interventions can be implemented by a range of personnel, including nurses working in emergency medicine (England & Jackson, 2013) or NonGovernment Organisations (Gilbert & Sinclair, 2019). The presumed causal mechanisms in knife crime education interventions are that by raising awareness around the impact and/or consequences of knife carrying and knife use for themselves and their friends and family, young people may be deterred. There can also be peer effects, if participants are less accepting of knife carrying by their friends, and by word of mouth to friends and siblings. There may be an adverse effect if the education creates a misperception regarding the prevalence of knife ownership and so encourages participants to carry
