Schools & Education Methodology

We identify nearby schools using distance calculations from postcode centroids, paired with Department for Education registry data and Ofsted ratings.

Data Sources

  • Department for Education (DfE) School Registry — National register of all schools with postcode, type, and capacity
  • Ofsted Ratings — School inspections and overall judgments (Outstanding, Good, Requires Improvement, Inadequate)
  • Postcode Directory (ONSPD) — Postcode centroids for distance calculations
  • Update Frequency — Schools registry updated termly; Ofsted ratings updated as inspections are published

Calculation Method

  1. Locate postcode — We identify the latitude/longitude centroid of the postcode
  2. Find nearby schools — We calculate straight-line distance to all schools in the DfE registry
  3. Rank by distance — We sort schools by distance (nearest first)
  4. Retrieve Ofsted rating — We link each school to its most recent Ofsted judgement
  5. Display top results — We show the 10 closest schools per phase (primary, secondary, special)

School Types Included

  • Primary Schools — Ages 4–11
  • Secondary Schools — Ages 11–18
  • All-Through Schools — Ages 4–18
  • Special Schools — Specialist provision
  • Independent Schools — Private schools (limited Ofsted data)

Distance Measurement

We calculate distance as straight-line (Haversine formula) from postcode centroid to school postcode centroid. This is an approximation; actual walking distance may vary by 10–20%.

Ofsted Ratings

RatingMeaning
OutstandingHighest category; likely inspected 3+ years ago
GoodMeets expectations; typical re-inspection cycle 3–5 years
Requires ImprovementBelow expectations; inspected annually
InadequateSerious concerns; likely to face intervention
Not Yet RatedNew school not yet inspected

Limitations

  • No Performance Data — We show Ofsted ratings only, not exam results, pupil progress, or league table rankings
  • Stale Ofsted Data — Outstanding schools may not have been inspected for 10+ years; ratings can become outdated
  • Catchment Areas Ignored — We show distance-based proximity, not actual catchment zones or admission likelihood
  • Private Schools Limited — Independent schools have fewer Ofsted inspections; data coverage is lower
  • No Specialisms Listed — We don't flag specialist provisions (STEM, language, arts colleges, etc.)
