Source coverage
DfE mainstream-school allocations for running costs for pupils aged 5-16, importer snapshot 23 August 2026.
What this means
The official mainstream allocation release does not provide a publishable row for this establishment.
What this does not mean
The school received no public funding or has no budget; other establishment types and funding streams use different publications.

Allocation is not expenditure. DfE says this release combines the schools block with several other revenue grants and excludes capital spending. Funding is shown for context and is never used in School Facts ordering, peer groups or quality claims. Source, licence and coverage.

Traffic volume is the context the collision count needs: a school beside a major road will record more collisions than one on a quiet street without being any less well run.

Every collision reported to the police within 500m of the school over the five years to 2024, from the Department for Transport's road casualty statistics. A high count usually says the school sits on or near a busy road, not that the school is unsafe — counts rise with traffic and with how built up an area is, and a rural school on a fast road may have fewer collisions but a worse one. Distances are straight-line from the school's recorded position.

The area around the school

5/10 Deprivation decile

Among around the middle for England.

4/10 Child poverty decile

Among the more deprived half of England for children in low-income families.

Indices of Deprivation 2019, for the small area the school stands in. 1 means the most deprived tenth of England, 10 the least. The second measure counts only children living in low-income families, which is the one that describes the intake a school is likely to draw on.

Matching uses only characteristics a school does not choose. It is not a ranking, and a close match on intake does not make two schools interchangeable — sixth form, faith character, admissions rules and simple geography all matter and are not in the calculation.

Questions this school record can answer

Which exact school is this?

Match the DfE URN, school name and address; names and structures can change while the URN remains the stable identifier.

What does the latest inspection evidence say?

Use the inspection date and framework shown. Do not compare a legacy overall grade directly with the newer report-card judgements.

How should I compare nearby schools?

Compare the same phase, cohort and academic year, then keep intake context and confidence intervals beside performance measures.

What must a parent verify?

Check current admissions rules, travel practicality, support for the child’s needs and the school’s latest official information before deciding.
