With the majority of school funding linked to pupil numbers, demographic decline can create powerful incentives for schools to compete rather than collaborate. Yet, if competition becomes our first response to falling rolls, we risk finances driving educational decisions rather than supporting them. For a generation of school leaders, pupil numbers have been the primary driver of school budgets, with rising rolls bringing increased income. However, many schools now face the opposite reality. Funding falls as pupil numbers decline, while key costs such as staffing, premises and utilities remain largely fixed, creating significant financial pressure. The speed at which rolls are falling intensifies the challenge. The Department for Education’s latest projections indicate that pupil numbers will decline over the next five years at twice the rate forecast a year before. With the minimum funding guarantee (MFG) calculated on a per-pupil basis, there are no financial safeguards against sustained falling rolls. The impact is felt unevenly too, with recent National Foundation for Educational Research (NFER) analysis showing that there is a clear link between deprivation and falling rolls. On average, schools with higher rates of disadvantage have seen more than double the drop in their pupil numbers compared with that in schools with lower free school meal rates. The conditions are ripe for a zero-sum game. Counting the cost of falling rolls The consequences of our misaligned funding system are already visible. Schools are reviewing staffing structures, merging year groups, limiting enrichment opportunities and reconsidering leadership models. Mixed-age classes are increasingly common. These are necessary, responsible decisions. School leaders are stewards of public money and cannot ignore financial reality. But neither should we pretend that a rational decision for one school will necessarily produce the best outcome for children across a locality. And that is the central problem. Falling rolls are experienced by individual schools, but they cannot be solved sustainably by individual schools acting alone. Our fragmented system makes this harder. Responsibility for standards, admissions, place planning, finance and intervention is distributed across councils, maintained schools, academy trusts, dioceses and central government. No single organisation has all the visibility or the levers needed to forge a coherent response. Prioritising a local approach Councils retain responsibility for pupil-place planning at system level. Meanwhile, schools and trusts are judged individually. Collaboration may be the right strategic answer, but the incentives still pull towards competition. A collaborative response begins with a shared local picture. Schools, trusts, local authorities and dioceses need reliable demographic and admissions data to understand where the pressure will fall over time. Data can support honest conversations about what provision a community needs, which schools are vulnerable and where change can be managed without sacrificing quality, inclusion or parental confidence. There should be one straightforward test to answer in a collaborative response: Does the proposed plan protect a sustainable pattern of high-quality education for all children in the area? School planning decisions are rarely straightforward, and they go beyond one school’s budget. A decision which secures one institution by destabilising another simply moves the problem down the road. Working across a locality, some schools may need to reduce published admission numbers, while others may need to reshape class structures, staffing models or leadership arrangements. In certain circumstances, formal partnerships, consolidation or the pooling of resources may provide a more sustainable future. Occasionally, the closure of a school may be unavoidable. Creating the conditions for collaboration National policy must align accountability, funding and place-planning responsibilities, and give local partners both the expectation and the practical ability to work together. The system should reward responsible collaboration and avoid destabilising already stretched schools and those serving our most deprived communities through sudden drops in income. School leaders will continue to control the controllables. Early and transparent planning gives governing boards, trusts and schools time to reshape provision deliberately, not reactively. Delaying difficult conversations often leads to deeper and more disruptive restructuring later. Collaboration helps local partners to make better decisions earlier. Before options narrow, schools can share specialist staff, professional development, back-office functions, curriculum expertise and inclusion provision. Trusts and maintained schools alike should be willing to work across organisational boundaries in the interests of their communities. With courageous leadership, a genuinely local strategy and a commitment for systems and politics to join up, we can replace the zero-sum game with collective stewardship. Protecting financial sustainability while keeping the needs of children and the quality of their education firmly in the lead should be the aim of a new game.
