Youth Justice Knowledge Transfer Partnership (KTP)

PYP is an evidence-based, research-informed framework of youth justice practice, developed through co-creation and participatory research with justice-involved children in Greater Manchester.

Youth-led principles

Participatory Youth Practice is based on a set of eight theoretically framed principles for youth justice practice that were co-created with children.

These are…

  • Let Children participate
  • Always unpick why (in relation to children’s behaviour)
  • Acknowledge children’s limited life chances
  • Avoid threats and sanctions
  • Help children problem solve
  • Develop children’s ambitions
  • Remember it’s children’s own choice to stop offending
  • Afford children a fresh start

You can see the film developed in partnership with children involved in the youth justice system, in which they explore their own perspectives on the importance of participatory practice.

Youth led principles for justice

Since the re-launch in 2023, Hannah Smithson and Tom Lang have provided PYP training sessions to approx. 200 colleagues across Greater Manchester. The PYP framework has been written into each of the nine GM Youth Justice Teams’ Business Plans, it forms the basis of the GMCA’s Youth Justice Transformation Strategy, its written into GMP’s 2025 Policing Plan and PYP is presented as a model of best practice by the Youth Justice Board in their revision of case management and by His Majesty’s Inspectorate of Probation.

Greater Manchester Youth Justice Services are working together to deliver first-class services to young people, victims, families and communities involved in the criminal justice system.

The group comprises of ten local authority areas each individually responsible for statutory delivery of youth justice, including safeguarding and protection of the public. The strategic aims are to reduce reoffending, first time entrants into the criminal justice system and the use of custody in line with the objectives of the Youth Justice Board and Ministry of Justice. This work also addresses issues specific to Greater Manchester and is informed by academic research.

This collaborative approach is supported by the Youth Justice Board, Ministry of Justice and Greater Manchester Mayor’s Office.
