Why Sustainable Schools Depend on Sustained Headteachers
Claudia Cubbage is known for her work in leadership and career development, particularly within education. She is the founder of RenewEd Ltd and is currently developing the RenewEd book series, drawing on over 25 years of school leadership experience.
School leadership shows a clear pattern over time. Some schools remain steady even under enormous pressure, while others slowly begin to feel as though they are unravelling.
It's rarely about policy. It is seldom the school improvement plan, the latest initiative, or even the spreadsheet.
More often, the difference lies in leadership capacity. Discussions about sustainable schools often centre on budgets, staffing, or curriculum. These are important, but they aren't the real starting point.
The sustainability of a school depends most on something often overlooked and less discussed, whether the headteacher is sustainable themselves. This becomes clear when we look beyond typical conversations about money or organisational structures, schools are most stable when headteachers have the capacity to think and lead for the long term.
After eight years as a secondary headteacher, I saw that a school’s success often rests on something less visible than strategy or structure, the leader’s ability to sustain their own thinking, energy, and perspective. This insight is at the heart of the headteacher coaching we provide at Renewed Ltd, and also informs how we support leaders considering professional change through career-change coaching.
Leadership erosion rarely happens overnight
Leadership burnout rarely manifests suddenly, it develops quietly over time through constant cognitive load, complex decisions, and the isolation that often accompanies senior roles.
Gradually, strategic thinking gives way to tactical survival, as leaders shift from long-term vision to week-by-week pressures. Instead of thinking about where the school needs to go next, leaders find themselves focused simply on getting through the week. And when that happens, the entire school feels the impact.
The hidden cost of leadership isolation
Headteachers operate in one of the most complex professional roles I have encountered. They develop staff, support leaders, manage safeguarding, respond to parents, work with governors, and handle accountability. At the same time, they must make calm, strategic decisions that shape the school in the long term.
Most headteachers lack protected time to think. After 25 years in senior roles and eight as a headteacher, I’ve seen leaders lose the time and space to reflect and lead effectively.
When that space disappears, something important changes:
Decisions become more reactive.
Confidence narrows.
Leadership identity shifts from clear direction to constant problem-solving.
This is not a failure of capability. It is a structural challenge within the role itself. Leadership eventually becomes unsustainable without reflection.
Why coaching matters for school leaders
Executive coaching is common for senior leaders in many sectors. In education, people often misunderstand coaching.
Many see it as only for struggling leaders. In reality, coaching is most powerful when it is preventative.
Headteacher coaching at Renewed Ltd provides ongoing support, giving leaders protected space for reflection, clarity, and effective strategy development, not as a remedial measure but as professional support.
When headteachers have access to a confidential professional space to think through complexity, several things begin to shift:
Decision-making becomes calmer and more proportionate.
Strategic thinking returns.
Governor and staff relationships become clearer.
Leaders begin responding rather than reacting.
In short, leadership capacity expands again. And when leadership capacity expands, the school stabilises around it.
When leaders begin questioning their path
Another signal of leadership strain is the quiet questioning that often appears after years in demanding roles.
Some headteachers start to wonder whether they still want the role they once loved. Others begin exploring alternative career paths or speaking with a career change coach because something no longer feels aligned with their goals. Sometimes a career transition really is the right next step.
Often, the issue isn’t the job but a lack of time to pause and reconnect with purpose. Clarity rarely emerges amid operational pressure. It appears in reflective space.
Rethinking what sustainable schools really mean
If governing bodies, trusts and policymakers genuinely want sustainable schools, the conversation needs to expand beyond structures and systems.
The question is not only: How do we sustain the organisation? We must also ask: How do we sustain the leader?
Coaching should go hand in hand with appraisal and development. It is not just for failing leaders, it is part of the leadership infrastructure. It protects the most important school resource, clear thinking, at the top.
At Renewed Ltd, we help school leaders through headteacher and career-change coaching, guiding them toward decisions that align with purpose and sustainability.
In my first book, RenewEd Leadership: How Coaching Transforms Headteachers and Schools, I explore what happens when school leaders intentionally create structured thinking space through coaching. Sustainable schools are not built through documents, initiatives or accountability frameworks alone.
Sustainable schools are created by leaders who maintain the space to think clearly, lead with intention, and care for their own sustainability in one of the most demanding public service roles.
True sustainability begins by nurturing and supporting headteachers, ensuring they are equipped to sustain both themselves and their schools well into the future.
