GAG pooling is a spreadsheet conversation right up until the point it is not. Then it becomes a conversation about fairness, identity, trust, control and whether the phrase 'one trust' actually means anything when money starts moving away from the school gate.
That is why it can make sensible people behave defensively. It is not because school leaders do not understand the technical position. Most do. The Academy Trust Handbook allows a multi-academy trust to amalgamate General Annual Grant funding into one central fund, provided the trust considers each academy's funding needs and allocations, has an appeals mechanism, and excludes PFI funding.
So the live question is rarely: can we do this?
The better question is: are we mature enough to do this without damaging the trust we are trying to build?
Permission is not the same as readiness.
The principle is simple. The reaction is not.
The equity argument for GAG pooling is powerful. A trust is not responsible only for the children in schools with strong rolls, healthy reserves or a favourable context. It is responsible for all of its children. That is easy to say in a strategy document and much harder to live by when one academy has built up comfort and another academy needs support.
If School A has a staffing model that still works and School B has a fragile curriculum, falling numbers, high SEND pressure and a roof that has clearly given up on optimism, what should the trust do? Leave each school to live within its own numbers? Or deploy the collective resource where it will make the biggest difference? That is the moral case for pooling. Funding follows need, not history. Resource follows pupils, not habit.
And that is also why it is difficult. Because a school does not experience its budget as 'historic allocation'. It experiences it as the teaching assistant who might go, the intervention that might stop, the class structure that might change, and the promise the headteacher made to parents last term.
Closest point of affinity: the bit trusts overlook
School-level resistance to GAG pooling is often described too lazily. It is not always parochialism. It is not always empire-building. It is not always a failure to buy into the trust.
Often, it is simply the closest point of affinity doing exactly what it does.
A headteacher's closest point of affinity is the school. They know the children by name. They know the parent who will be waiting at reception. They know which corridor is unsettled after lunch. They know which member of staff is holding too much and smiling through it. They know the texture of need because they walk through it every day.
The trust board's duty is different. It has to look across the whole organisation. It has to weigh risk across all schools. It has to see sustainability, educational improvement, reserves, curriculum viability, workforce pressure, estate risk and the uncomfortable fact that public money can only be spent once.
Both views are legitimate. The school sees proximity. The trust carries responsibility. GAG pooling becomes painful when those two truths are treated as opponents rather than perspectives that need joining up.
Do not sell pooling as efficiency. Sell it as equity – if you can evidence it.
This is where some trusts get the communication wrong. They describe GAG pooling as a financial operating model. Technically, fine. Emotionally, hopeless.
No headteacher was ever reassured by being told that a new financial operating model will create enhanced resource optimisation across the group. That sort of sentence deserves to be taken outside and gently retired.
The honest version is this: We are moving money because need is not evenly distributed, and our responsibility is not limited to the school that generated the funding.
That is a braver message. It is also a clearer one.
But it only works if the trust can show the evidence. Where is the need? What is the educational case? What risk is being reduced? What improvement priority is being funded? What will change for pupils? How will trustees know the decision has worked?
If those answers are not clear, do not call it equity. Call it what it is: a reallocation that has not yet earned confidence.
Why the conversation moves so quickly
The spreadsheet is where pooling starts. It is rarely where the argument ends.
The centre has to earn the right
There is another awkward truth here. Central teams do not earn the right to pool funding by existing. They earn it by being useful. If schools experience the centre as slow, distant, compliance-heavy or mainly interested in templates, then GAG pooling will feel like extraction. It will feel like money leaving the school to feed a machine.
If schools experience the centre as credible, responsive and genuinely helpful, the conversation changes.
Finance that gives heads numbers they can trust; HR that answers properly; Payroll that just works; Procurement that creates savings schools can actually feel; Governance support that makes meetings sharper and School improvement that knows the context rather than performing at it.
That is when the centre starts to look like capacity, not cost. And that matters because a pooled model requires confidence. Not blind trust. Not forced positivity. Confidence built from repeated evidence that central decision-making improves life for schools and pupils.
The boardroom risk: pooling as a cover story
Trustees should be careful here. GAG pooling can be a strong strategic tool. It can also become a very neat cover story for weak financial planning.
If a trust is pooling because one school has a clear, evidenced, time-bound need, that may be entirely right. If a trust is pooling because structural deficits have been allowed to drift and nobody wants to have the hard conversation, that is not equity. That is avoidance with a policy attached. The board should not ask only whether pooling is lawful. It should ask whether the model is honest.
Is the trust funding improvement, or subsidising denial? Is it moving resources to children who need it, or protecting adults from decisions they have delayed? Is the model transparent enough to stand up in front of heads, local governors, trustees and the DfE?
If the answer is no, pause. Fix the governance before moving the money.
The local governance point nobody should duck
Local governors are often caught in the middle of this debate. They are asked to champion the trust view while still being rooted in the school community. That is a difficult position if the scheme of delegation and funding model are not crystal clear.
Where GAG is pooled, local governance cannot be left pretending it has the same financial autonomy it had before. That does not mean local governors become decorative. Far from it. Their role becomes sharper: understand school-level need, test whether the trust has heard the local context, scrutinise impact, and feed back honestly where the model is not landing.
But they need the truth. They need to know what is delegated, what is not, what can be challenged and how challenge will be heard. A trust that muddies this creates unnecessary tension. A trust that explains it properly gives everyone a better chance of behaving like adults in the same organisation.
So, should trusts pool GAG?
Sometimes, yes. Sometimes, absolutely not.
That may be the least exciting answer, but it is the right one. GAG pooling is not a badge of maturity on its own. A trust can pool badly. A trust can top-slice well. A trust can use partial pooling, targeted central funds or a phased approach and achieve a better result than a rushed full pooling model. The question is not whether pooling sounds strategic. The question is whether it helps the trust make better decisions for children.
Where there is a strong shared culture, trusted reporting, clear governance, credible central services and a board that can explain its reasoning, pooling can be powerful. It allows funding to follow need. It allows the trust to support vulnerable schools before they tip into crisis. It allows investment in improvement priorities that no single school could fund alone.
Where those foundations are missing, pooling can corrode trust quickly. It can turn every allocation into a suspicion. It can make heads feel punished for good management. It can make local governors feel bypassed. It can make the centre look like it has confused authority with credibility.
That is why the implementation matters as much as the principle.
Boardroom questions worth asking:
- What problem are we solving?
- Who loses comfort, and why?
- Where is the evidence of need?
- How will heads challenge fairly?
- What will pupils gain from this?
If the answer is not clear enough for a headteacher to repeat, it is not ready.
The Keystone view
Our view is straightforward: do not start with the mechanism. Start with the responsibility.
If the trust genuinely believes it exists for every child, then it has to be prepared to ask whether its money is being used where it is most needed. That question may lead to GAG pooling. It may not. But it should definitely lead to a more honest conversation about equity, accountability and the role of the centre.
The best trusts will not ask, 'How do we make schools accept this?'
They will ask, 'How do we build a model that is fair, evidenced, transparent and strong enough to survive scrutiny?'
Because GAG pooling is not really a test of finance. It is a test of whether the trust is ready to act like one organisation when the conversation gets uncomfortable. And if that sounds blunt, good. Some issues in trust life need fewer soft edges.
Need an independent perspective?
At Keystone, we help academy trusts assess whether their financial model is fair, sustainable and right for their schools. From independent finance reviews and governance assurance to interim CFO support and practical advice, we provide the clarity trusts need to make confident, well-evidenced decisions.
