SEND provision is one of the most complex and high-risk challenges facing senior leaders in MATs. Rising numbers of pupils with SEND, delays in EHCPs, and limited local authority capacity mean trusts increasingly need to design inclusive systems from the outset. Government policy signals a shift towards mainstream inclusion, supported by substantial investment, yet school leaders remain concerned about funding sustainability and clarity over future SEND provision. This keynote panel will explore what true inclusion looks like in practice and how trust-wide cultural and systematic shifts can be achieved. What does mainstream inclusion look like beyond rhetoric, for example: in staffing, curriculum, environment, and leadership culture? How can trusts embed inclusion across leadership, teacher development, and workforce planning amid training and workload pressures? How can trusts maintain high outcomes while expanding inclusion? What frameworks or partnerships can enable this? How should leaders balance funding realities with the ethical imperative to provide equitable education for all learners?
