How schools are matched

We compare open primary schools in England that teach through to age 11. We match current eligibility for free school meals first, then first language other than English, SEND and pupil numbers. The same age range is preferred. Region, faith and school type have a smaller influence.

A similar intake does not explain a difference in results. Use this list to choose schools to investigate, then check their reports and local circumstances.

View the matching calculation and data sources

SEND is calculated from pupils with SEN support or an EHC plan, divided by the school roll. We only calculate it when the source counts, year and coverage agree. It is rounded to two decimal places here.

Matching weights: FSM 45%, EAL 25%, SEND 20%, pupil numbers 10%. Lower matching scores mean more similar pupil context. Context bonuses can take a score below zero; a score is not a rating or a percentage.

Open England GIAS Primary; statutory low age at most 5 (including nursery ages 2/3) and high age 11. All four inputs required in the same academic year. Prefer exact low/high ages when at least 10 candidates remain after the report-card filter; otherwise disclose relaxation. Outcomes never select or rank peers. Context bonuses require nonmissing exact region, religious character and establishment type code; missing context earns no bonus. Lower distance is closer, including negative totals after bonuses.

5731 schools were eligible; 10 are shown.

  • fsm: Absolute percentage-point difference / 100
  • eal: Absolute percentage-point difference / 100; First language other than English
  • send: Absolute percentage-point difference / 100
  • size: Absolute pupil-count difference / max(target pupils, candidate pupils)

SEND formula: 100 * (SEN_support + EHC_plan) / characteristics.pupils; same school, Academic year and year; SEN total_pupils must equal characteristics.pupils. Ties are resolved by URN ascending.

Schools can be excluded for more than one reason:

  • Not a primary school: 21888
  • Does not cover the full primary age range: 28649
  • Not open: 25399
  • The selected school: 1
  • England location unverified: 3045
  • FSM percentage missing: 192
  • First-language percentage missing: 192
  • Pupil number missing: 192
  • SEND: published SEN support, EHC plan or pupil total missing: 192
  • Different age range: 8365

Missing means no usable figure was provided. Suppressed means the publisher withheld it. Unavailable means no usable value can be shown; check the source and published code. Not applicable and low reliability retain the publisher’s stated limits.
