Youth Justice, Ahead of Print.
The ‘Child First’ guiding principle for practice in the Youth Justice System of England and Wales has a growing international evidence-base and is fully embedded in policy/strategy, yet remains underdeveloped in consistent, coherent practice across local agencies and areas. This raises the potential for a policy–strategy practice implementation gap. Focus-group consultations (n = 11) with professional stakeholder groups (community, custody, strategy, inspectorate, and research) explored perceptions of the practice challenges to understanding, implementing and supporting Child First. Qualitative analysis identified child-centrism, professional relationships and cognisance as pivotal features of the effective realisation of Child First in practice.
