Methodology and sources

Every figure on this site comes from official open data, reproduced without adjustment except where a page says a value is calculated (and then the calculation is stated). This page lists the sources, defines each measure, and — just as important — states what the data does not show.

All sources are published under the Open Government Licence v3.0. Raw files are fetched by script and figures are recomputed from them on every build; the build fails if a sampled figure stops matching its source.

Definitions

Issued within the 20-week limit
Regulation 13(2) of the SEND Regulations 2014 requires a final EHC plan within 20 weeks of the request for assessment. The headline series excludes exceptional cases — cases where regulation 13(3) allows the deadline to be exceeded (for example, the child was away for the summer holidays or advice was delayed for defined reasons). This matches the DfE headline measure. Each chart's table also carries the series including those cases, which is always equal or lower.
Requests for assessment refused
The percentage of requests for an EHC needs assessment where the authority decided not to assess, as published by DfE. Collected on a person-level basis only from 2023, so no earlier years are shown.
SEND Tribunal appeal rate
Appeals registered with the First-tier Tribunal (SEND) against decisions of the authority, as a percentage of that authority's "appealable decisions" in the same calendar year — DfE's published measure joining HMCTS appeal records to DfE decision counts. The England comparator on this site is calculated as the sum of appeals across all authorities divided by the sum of appealable decisions, from the same file.
Decided appeals found at least partly for the family
Of appeals decided at a tribunal hearing in England, the percentage where the decision was in favour of the appellant (in whole or part), from MoJ Table SEND_1. Most registered appeals never reach a hearing decision — many are conceded by the authority or withdrawn first — so this percentage is of decided appeals only, and the number decided is always shown alongside.
Statistical neighbours
The ten authorities DfE's children's-services benchmarking model rates most similar on socio-economic characteristics (2021 Census variables). Comparing an authority to its statistical neighbours is fairer than comparing to a national average, because it holds demographics roughly constant. Cumberland, and Westmorland and Furness, are not in the DfE model following local government reorganisation; their pages compare against England only.

What this data does not show

Postcode lookup

The postcode box queries postcodes.io (Open Government Licence / OS OpenData) in your browser; no postcode is sent to this site or stored. EHC plans are a duty of upper-tier authorities, so in two-tier areas the county council is returned, not the district.
