School improvement is rarely experienced as a neat or linear process. For school leaders, it sits at the intersection of accountability pressures, curriculum ambition and moral purpose, often pulling in competing directions at once.
This post builds on earlier reflections about short-term interventions and long-term curriculum thinking and shifts the focus to leadership perspective. Rather than revisiting the tension between quick wins and sustainable change, it explores how headteachers make sense of improvement when the goal is durability, coherence and trust over time.
Bringing together three headteachers’ perspectives, the post examines how observation, alignment and confidence in people shape sustainable school improvement, particularly in complex, high-stakes contexts where decisions must be both strategic and humane.
Headteacher 1: Ursula Byrne
Observation and culture first
My first point of call would not be a question but a visit to the area or discipline of concern while it was operational. The atmosphere would give me what I needed. I would then ask both staff and pupils the same question: ‘Do you look forward to coming to lessons, and why?’ I would study faces for reactions of boredom or passion. I do a lot of looking.
Ursula prioritises understanding pupils and staff. Improvement begins with visibility: seeing lessons in action, noticing interactions and listening carefully to those who experience school every day.
Engagement, culture and ethos are viewed as foundational indicators of health. Facial expressions, tone and energy often reveal more than any dataset. From this standpoint, sustainable improvement starts with curiosity and observation. By looking and listening closely, leaders can judge whether there is something strong to build on, or whether improvement will require appointing a new lead to take the work forward. Any subsequent action is rooted in the reality of the school rather than assumptions or headline outcomes.
Headteacher 2: David Wright
Data-aligned, holistic strategy
Does the data match the teaching and learning, curriculum, behaviour, attendance and overall journey? Context is key. School improvement is about long-term sustainable growth. You need to explore the past three to five years, both across the school and within specific subject areas.
Results matter because they open doors to the next stage of a pupil’s educational journey, but they only work when everything else is aligned.
David emphasises coherence. Data is important, but only when it reflects the experience of the school and is interpreted within context. Teaching and learning, curriculum intent, behaviour, attendance, safeguarding, pastoral care, SEND provision, financial stability and community engagement must all work together.
Leadership, from this viewpoint, is about setting direction and clarity. It means showing the way, explaining the why, removing barriers and fostering independent and critical thinking. Sustainable improvement is collective work, built on shared values and a united school community rather than isolated initiatives.
Headteacher 3: Andrew Jenkins
Trust, talent and confidence in information
The question I would ask is how much I can trust the information that is being shared with me, and that comes down to the confidence I have in my people, particularly my leaders. Are the right people, in the right place, looking at the right things?
In high-stakes environments with limited resources, pupil outcomes, holistic development and experience are ultimately shaped by the people, teachers and leaders, who design, review and refine the curriculum and wider school journey. Leaders must have confidence that the information they receive is valid and reliable. It must measure what it claims to measure and be linked to assessment systems aligned with a well-sequenced curriculum that has a clear, pupil-centred intent.
Sustainable systems demonstrate impact over time but remain adaptable to different cohorts and contexts. This is not the work of a single leader. It relies on effective, often organic collaboration between leaders who triangulate information, challenge assumptions and make informed decisions together. As leaders demonstrate impact and sound judgement, greater autonomy becomes both possible and necessary. Trust is especially critical in large, complex schools serving inclusive and diverse communities.
Andrew is a strong advocate of the leadership philosophy adopted by media giants such as Netflix, which revolves around increasing the talent density of an organisation. Applied to schools, this means that headteachers who invest time in developing the right people and placing them in roles where their impact is visible and tangible reduce the need for control, short-term interventions or superficial quick wins. In talent-dense organisations, improvement is more sustainable, resilient and responsive to complexity.
Observation and experience matter. Culture, engagement and ethos provide critical insight into where improvement is genuinely needed.
Data should inform, not dictate. Information must be valid, reliable and rooted in strong curriculum and assessment design.
Trust and people are central. Sustainable improvement depends on capable leaders working collaboratively with appropriate autonomy.
Holistic alignment is essential. Curriculum, outcomes, behaviour, pastoral care and community engagement must connect coherently.
Long-term thinking matters. Investing in people and systems builds lasting improvement and reduces reliance on short-term solutions.
Sustainable school improvement is not a destination but a disciplined, reflective process, grounded in trust, context and a shared commitment to doing what is best for pupils over time.
Thanks for stopping by. Wishing you a restorative February half-term. I’ll be back soon with more reflections to share.
