How are schools actually funded?
Through a formula rather than a negotiation — money follows pupils and their characteristics, distributed through national and local allocation rules that almost nobody outside school business management understands.
The basic structure:
A per-pupil amount, which is the bulk of it. More pupils means more money; falling rolls means falling income, which is why a school losing a class of pupils faces immediate financial trouble.
Additional weightings for characteristics associated with lower attainment — deprivation, English as an additional language, prior low attainment, and mobility.
Lump sums intended to recognise fixed costs, which matter disproportionately to small schools.
Area cost adjustments for higher salary costs in some regions.
Targeted funding such as pupil premium, allocated for disadvantaged pupils.
Separate funding streams for pupils with high needs, for capital works, and for sixth forms, which are funded on a different basis entirely.
Where the money goes. Overwhelmingly on staff — commonly 75–85% of a school's budget. This is why almost every significant saving involves staffing, and why a small percentage squeeze on income translates into redundancies rather than a reduction in trips or books.
Why schools plead poverty while funding rises in cash terms. Several pressures compound: pay awards not fully funded centrally; employer pension and national insurance cost increases; energy and catering inflation, which hit schools harder than headline inflation; rising high-needs costs exceeding the high-needs budget; and falling pupil numbers in areas with declining birth rates.
What parents may not realise: requested "voluntary contributions" are genuinely voluntary and cannot be required for curriculum activities; schools cannot charge for anything within the school day that forms part of the curriculum; and parental fundraising is now a meaningful part of some school budgets, which itself widens inequality between catchments.
Academies and maintained schools are funded on broadly comparable formulas but through different routes, with trusts able to pool resources across schools.
UK-focused; systems differ substantially by country.
