The concept of nurture establishes the importance of supporting children's social and emotional skills, wellbeing and behaviour. As such, a Welsh Police Force implemented the "Heddlu Bach" (Mini Police) scheme in three Welsh Primary schools in the 2017-18 academic year. Using an evaluation research design, three focus groups were undertaken in each of the three schools with pupils that were involved in the scheme. Supplementary methods included semi-structured interviews with other stakeholders (teachers, teaching assistants, police community support officers), as well as documentary evidence in the form of pupil/school biographical information. The results reveal that the scheme developed children's aspirations, resilience, and self-esteem/self-worth. The children were engaged and immersed in their mini police 'duties' and this resulted in a positive view of both their own abilities, the police and police work. This engagement was set against a backdrop of communities within areas of social and economic disadvantage, and where the police are often viewed adversely. By being part of the scheme, the children gained a range of transferable skills and attributes. Wider benefits were also evident with whole family/community/school engagement and curriculum aspects relating to personal and social development, nurture, citizenship and environmental issues.
