We are pleased to introduce the updated School Improvement Guidance, which strengthens the way we support improvement across Wales. The guidance reflects the outcomes of the recent review of roles and responsibilities and sets out a clear, shared ambition: that every learner is supported to achieve their full potential within an equitable and collaborative education system.

At the centre of the guidance is a straightforward principle: improvement is a shared responsibility.
Schools should not work in isolation. By developing strong local improvement communities, partners can draw on collective expertise, respond to challenges more effectively, and develop solutions that are sustainable and focused on learners’ needs. This is about building a culture rooted in openness, trust and ongoing learning.
The guidance is underpinned by five core principles:
- Collective responsibility for raising standards for every learner.
- Purposeful collaboration that brings in external perspectives and fosters professional dialogue.
- A focus on activity that improves learning.
- Building capacity within the school system, so expertise is shared and strengthened.
- Clarity and coherence across partners, connecting local needs with national priorities.
This is an exciting opportunity for schools, local authorities, and partners to work together in new ways – through vertical and horizontal collaboration, robust self-evaluation, and strategic planning that truly makes a difference. The aim is clear: better outcomes, stronger leadership, and a more inclusive education system for Wales.
We encourage all partners to engage fully with this guidance and play an active role in shaping an improvement system that works for everyone. By working collectively, we can build a system that responds to today’s challenges while laying firm foundations for future success.
