School funding formulas: why schools in the same city receive different budgets

Two state schools separated by a twenty-minute walk can receive vastly different sums of money for each child they teach. In many towns and cities, the funding gap between neighbouring comprehensives or primaries reaches well over a thousand pounds per pupil each year.

The difference is not an administrative oversight. It is the intended result of school funding formulas, which calculate budgets using a series of weightings designed to direct more cash to pupils who require more support to educate.

How the baseline formula allocates money

Most funding systems start with a universal building block: the basic entitlement. Every pupil brings a flat baseline amount of cash to their school simply by being on the roll. Primary pupils attract one rate; secondary pupils attract a higher rate because specialist subject teaching, laboratory equipment, and GCSE staffing requirements push operating costs up.

If funding stopped at this baseline, every school of 800 pupils would receive nearly identical general funding. In practice, the baseline makes up only the foundation of the budget. The rest is determined by pupil demographics and local characteristics.

Why deprivation weighting drives the biggest gaps

Deprivation is the single largest variable behind disparities between schools in the same district. Under the National Funding Formula in England, the Department for Education distributes supplementary funds based on both current and historical poverty measures.

Funding formulas track pupils eligible for free school meals over the previous six years, as well as area-level deprivation indices such as the Income Deprivation Affecting Children Index (IDACI). A school serving an estate with high unemployment and intergenerational poverty receives a substantial top-up for a large majority of its register. Two miles away, a school drawing from an affluent catchment receives negligible deprivation funding.

Policymakers defend this gap by pointing to the cost of intervention. Schools in poorer areas routinely spend more on speech and language therapy, pastoral support teams, attendance officers, and breakfast clubs—services schools with wealthier intakes rarely need to provide at scale.

English language and additional educational needs

Other weighted factors focus on learning barriers. Pupils who enter school with English as an additional language (EAL) attract targeted funding for their first three years in the state system to cover language acquisition support.

Formulas also weight for low prior attainment. Primary children who fail to achieve expected early learning goals, or secondary students entering year seven below expected reading and maths benchmarks, bring additional money. Because pupils who struggle early tend to cluster in specific neighbourhoods, certain schools see their budgets compound further through these additional need factors.

Premises and the high needs crisis

Not every funding divergence traces back to pupils. Physical buildings alter the equation. Formulas often include fixed lump sums for basic school operation, alongside premises factors covering split-site operations, exceptional rent costs, and rates.

Older Victorian school buildings frequently drain higher proportions of baseline funding on heating and maintenance compared with modern academy buildings constructed under private finance initiatives, creating hidden operational imbalances that per-pupil figures do not capture.

Compounding these formula differences is special educational needs and disabilities (SEND) provision. While national formulas provide "notional" inclusion funding inside general school budgets, councils increasingly run steep deficits in their dedicated high-needs blocks. Headteachers in inclusive schools often find themselves absorbing statutory specialist support out of ordinary school funding, widening the perceived resource divide between schools that actively admit children with complex plans and those that do not.
