Children and young people who come into conflict with the law tend to be disengaged with education and learning. This paper reports on research from an EU Erasmus+ project in Spain, Italy, Germany and the UK. The research focused on the impact of Authentic Inquiry (AI) on learners in custodial or youth justice settings and the impact on educators and their pedagogy. Quantitative data (from 82 educators and 73 young people), demonstrated the young people could be re-engaged with education and learning as evidenced in the change in Learning Power profiles. Qualitative data (from 16 educators and 14 young people) showed the greatest impact to be on the emotional component of engagement. The AI had an impact on educators as learners by improved Learning Power profiles and on their pedagogical approach. Ways to embed the approach into education in youth justice settings in the different country contexts are discussed.
