When is excluding a SEND pupil unlawful?

The three ways an exclusion becomes unlawful

Excluding a SEND pupil is unlawful if it’s done informally (sent home to ‘cool off’ even with your agreement), because of needs the school can’t meet, or as disability discrimination under the Equality Act 2010. These are three separate routes, and a single decision can be lawful on one and unlawful on another, so it’s worth taking them in turn.

First, informal or unofficial exclusions. Sending a pupil home to calm down, asking a parent to collect them early, or putting a child on an unagreed reduced timetable is unlawful however brief it is, and the Department for Education’s statutory guidance is explicit that this stays unlawful even when the parent agrees to it DfE statutory guidance. If a child is sent home for behaviour, that is an exclusion and it must be recorded and processed formally. Parental consent does not turn an informal exclusion into a legal one.

Second, the reason for the exclusion. It is unlawful to exclude a pupil simply because they have special educational needs or a disability the school feels it cannot meet, for their academic ability, or for failing to meet a condition before being allowed back — for example, requiring a parent to attend a reintegration meeting first.

Third, disability discrimination. Even a fixed-period or permanent exclusion that has been processed correctly can still be unlawful if it discriminates against a disabled pupil. The provision most often engaged is discrimination arising from disability: treating a pupil unfavourably because of something connected to their disability — such as behaviour that flowed from it — unless the school can show the exclusion was a proportionate means of achieving a legitimate aim Equality Act 2010, s.15. A failure to make reasonable adjustments that then leads to the exclusion can itself be unlawful s.85.

Two points the headline rule misses

None of this depends on a diagnosis or an EHCP. The Equality Act protects a pupil whose impairment has a substantial, long-term effect on day-to-day life, whether or not it has been formally labelled, and the duty applies if the school knew, or could reasonably have been expected to know, about the disability.

The second point is who decides. A challenge to the exclusion decision itself goes to the governing board and then, for a permanent exclusion, an independent review panel. A disability discrimination claim is separate: it is made to the First-tier Tribunal (SEND) and must be brought within six months of the act complained of Child Law Advice. That means a permanent exclusion the review panel upholds can still be found discriminatory by a different body on a different test — a distinction many schools and parents miss.

Why it matters now

Recording matters because the record is the evidence: an exclusion that was never logged cannot be defended later, and an undocumented ‘cool-off’ pattern is exactly what an unlawful-exclusion complaint is built on. The DfE statutory guidance is also being revised — an updated version comes into force on 26 July 2026 — so check the in-force edition before relying on specific paragraph numbering.
