What is Youth Justice? A Guide to Services, Support & Child First Approach

Youth justice is the system of services and interventions aimed at preventing offending and reoffending among young people aged 10–17. It brings together local authorities, police, courts, Youth Justice Services (YJS), health services, education providers, and voluntary organisations to support rehabilitation and protect public safety. 

Modern youth justice focuses on early intervention, restorative practice, and addressing the underlying causes of offending such as mental health issues, family conflict, school exclusion, and exploitation. This approach recognises young people as children first, understanding that they have developing brains and capacity for change, and that positive relationships and support are more effective than punitive measures alone.

Why Youth Justice Matters

Core+ Strengths: 

  • Real-time performance analytics 
    Built-in Reoffending Toolkit provides live tracking of intervention effectiveness with no manual input required 

  • Evidence-based impact 
    Core+ enables services to demonstrate proven outcomes like 51% reduction in reoffending frequency     

  • KPI dashboard integration 
    Comprehensive performance monitoring across all Youth Justice Board indicators     

  • Keeps young people and communities safer 
    Through preventative work and rehabilitative support, youth justice services reduce the likelihood of repeat offences and future harm. 

  • Supports vulnerable young people 
    Many young people have unmet needs such as trauma, care experience, or learning difficulties that require targeted support, not just punitive action. 

  • Promotes rehabilitation over punishment 
    Evidence shows young people respond better to positive, relationship-based intervention that addresses root causes. The Child First approach, endorsed by the Youth Justice Board, places children’s welfare, rights, and potential at the centre of practice emphasising early intervention, strengths-based support, and minimal use of formal sanctions wherever possible. 

  • Ensures statutory compliance 
    Local authorities have legal duties under the Crime and Disorder Act 1998 and Youth Justice Board (YJB) guidance to deliver effective youth justice services.

Case Example: Reducing Reoffending 

Local authorities have implemented integrated youth justice case management systems to manage complex cases more effectively. systems to manage complex cases more effectively. 

Linked to youth support services and education teams, these solutions improve engagement with young people, delivering both better outcomes such as reducing reoffending with the help of the reoffending toolkit for safer communities. 

A key element of this is the Reoffending Toolkit, a Youth Justice Board–developed resource that provides local authorities and their partners with detailed data and analytics on patterns of reoffending. By using the toolkit alongside systems such as Mosaic, councils can: 

  • Identify trends and risk factors at an earlier stage. 

  • Monitor the effectiveness of interventions across different cohorts. 

  • Benchmark local performance against regional and national averages. 

  • Target resources more precisely to reduce repeat offending. 

Combining integrated case management with the Reoffending Toolkit helps ensure that decisions are evidence-based, preventative work is better focused, and services can demonstrate measurable impact on reoffending rates. 

 

Core+ Strengths: 

  • Timeline Data Visualisation: Interactive timeline views showing outcome dates, reoffending patterns, and cohort analysis with zoom and pan functionality
  • Advanced Filter Builder: Custom cohort definition using multiple criteria with saved parameter sets for repeated analysis
  • VJB Toolkit Export Integration: Seamless data export to Youth Justice Board toolkit format for PNC comparison and national benchmarking
  • Binary and Frequency Rate Calculations: Automatic calculation of reoffending statistics including proportion analysis and offence frequency metrics 
     

Consider the case of a 15-year-old who has been charged with theft and criminal damage - their third involvement with Youth Justice services. Previously, fragmented information systems meant that each new offence was treated in isolation, with limited understanding of underlying patterns or previous intervention attempts. 
 
Using Core+ with its integrated approach, practitioners can immediately access the complete case history, including previous AssetPlus assessments, intervention programmes attended, family circumstances, educational needs, and any health or mental health considerations. The Reoffending Toolkit highlights that this young person fits a pattern of escalating offending linked to school exclusion and family breakdown. 
 
The AssetPlus assessment, conducted using Core+'s structured framework, reveals that while the young person has been engaging in offending behaviour, they also have significant strengths including artistic ability, close relationships with grandparents, and motivation to pursue vocational training in construction. Previous interventions focused primarily on offending behaviour without addressing underlying trauma from domestic violence or the impact of school exclusion. 
 
Based on this comprehensive understanding, practitioners design an intervention programme that includes trauma-informed counselling, family support work involving the extended family, educational re-engagement through alternative provision, and a construction skills programme that builds on the young person's interests and aptitudes. 

Core+ tracks progress across all intervention elements, enabling practitioners to adjust support as needed. The system's communication tools ensure that all professionals involved - Youth Justice worker, social worker, education specialist, and voluntary sector partners - remain coordinated in their approach. 
 
Six months later, the young person has completed their construction pre-apprenticeship, is living stably with grandparents with ongoing family support, and has not reoffended. The Reoffending Toolkit data shows this as part of a broader pattern of improved outcomes for young people receiving this more holistic, coordinated approach. 
 
This case demonstrates how Core+ enables the child-first approach in practice - seeing the young person as a child with potential and complex needs rather than simply an offender to be managed.
