Behaviour Hubs is a one-year programme of support (two years for multi-academy trusts [MATs]), available across England to mainstream primary and secondary schools, special schools and alternative provisions (such as pupil referral units). It aims to help senior leaders create the conditions for an effective and sustainable behaviour culture throughout their setting. The programme matches partner schools and MATs with a lead school or MAT with an exemplary track record in behaviour management. These lead settings work in close collaboration with their partner settings, identifying opportunities to improve behaviour culture and develop new behaviour policies and approaches. This report aimed to document the collaborative approach employed by the Behaviour Hubs programme and assess its implications for global policy. The public research team at Education Development Trust collaborated with the Behaviour Hubs programme delivery team to: (1) review key documentation, prior to and during programme delivery, to record the initial policy intentions and methodology; (2) carry out a thematic analysis of feedback and survey data from participating schools and MATs; (3) consider relevant Ofsted (Office for Standards in Education, Children's Services and Skills) inspection-grade evidence associated with participating schools; (4) calculate the per-pupil cost of the programme and compare it with cost effectiveness data from a range of similar interventions; and (5) draw together conclusions and implementations for policy delivery, particularly where those policies seek to implement the latest research evidence. The programme's approach can be seen as a form of policy reform that succeeds in balancing accountability, autonomy and support, within an evidence-based policy framework. The model of identifying the most successful practitioners and using them to support and lead the improvements of others is a valuable global policy lever that allows the integration of local wisdom into challenging reform agendas. By extension, such an approach facilitates the buy-in of schools receiving support. [This report was created in collaboration with Behaviour Hubs.]
