Identifying and supporting SEMH needs in schools: what the evidence says

Original source: Department for Education — Identifying and supporting children and young people with social, emotional and mental health needs: a rapid evidence review (ref RR1549, September 2025). Research evidence, not statutory guidance.

Social, emotional and mental health (SEMH) is now the second most common primary need among pupils on SEN support — behind only speech, language and communication needs — and around one in six pupils with an Education, Health and Care plan has SEMH identified as their primary need. In 2024/25, around 1.44 million pupils with identified special educational needs were educated in mainstream state schools. This DfE-commissioned rapid evidence review, led by UCL’s Institute of Education, set out what actually works when mainstream teachers identify and support SEMH needs — and what the evidence still cannot tell us.

The review drew on 15 studies covering identification and assessment, and 33 studies covering support. Its central message is uncomfortable for anyone looking for a quick fix: the most important variable in early identification is not a test, but the beliefs and knowledge of the adults in the room.

Identification is a training problem first

Misunderstanding and stigma around SEMH delay timely support and worsen outcomes. The review is explicit that comprehensive, ongoing professional development is the foundation that everything else sits on — without it, even good tools are misused.

Structured observation of behaviour is singled out as a practical, underused method for both spotting need and monitoring progress. Teacher nomination, based on professional judgement, works as a first screen — but the review found structured questionnaires and checklists are more accurate, particularly for internalising difficulties such as anxiety that are easy to miss because a quiet child is not a visible problem. The Strengths and Difficulties Questionnaire appeared most frequently across the studies and was useful for flagging ADHD, mental health and social-emotional difficulties.

The caveat matters for schools. Screeners are for flagging and planning, not for labelling or diagnosis. The review advises that any tool be interpreted with caution by staff without specialist qualifications, and that identification is most reliable when it draws on several informants — parents, teachers and the pupil — using more than one tool, because each source notices something different.

Support that works is ordinary, not exotic

At whole-school level, the review found token economies and check-in/check-out systems help pupils with behavioural challenges — but only when senior leaders genuinely back them and they are applied flexibly to individual needs rather than mechanically. A positive school climate is what turns these systems from exclusion into inclusion.

At classroom level, the effective ingredients are reassuringly familiar: targeted praise, rewards, choice, hands-on activity, and instructional methods that reduce cognitive load — Direct Instruction, explicit teaching, scaffolding, modelling, prompting, mnemonics and daily report cards. These were consistent winners for engagement and attainment, and the daily report card doubles as a home-school communication channel.

Targeted interventions reinforce the same pattern. Self-Regulated Strategy Development improved writing and self-organisation, though some versions need specialist training. Reading interventions built on Direct Instruction — Corrective Reading, Reading Mastery, Sound Partners, Stepping Stones to Literacy — were reliably effective, especially for younger pupils. Peer-mediated and small-group delivery showed promise; repeated reading alone did not.

The honest gaps

Three gaps deserve leaders’ attention. First, most screening tools lack standardisation or need specialist training, which limits how far mainstream schools can rely on them. Second, the evidence base skews heavily towards externalising behaviour and ADHD, leaving internalising needs — anxiety, withdrawal, low mood — relatively neglected. Third, much of the research rests on single-case designs that tell us about individuals but do not generalise easily to whole schools. The pupil’s own voice is also under-represented: there is little research on how pupils can meaningfully self-identify or shape their own support.

For a school leader, the practical reading is this: invest in staff understanding before buying tools, use structured observation and multi-informant screening as routine practice, keep universal teaching strong, and treat targeted interventions as a supplement to — never a substitute for — a calm, consistent, well-led school culture.

Practical takeaways for schools

Train all staff in SEMH awareness before buying any screening tool — misunderstanding and stigma are the main barrier to timely identification.
Make structured observation routine for both spotting and monitoring need.
Screen with a structured tool such as the SDQ and use multiple informants — parents, teachers and the pupil — rather than teacher judgement alone.
Never use screeners to label or diagnose; use them to flag need and plan support.
Keep universal teaching strong: explicit instruction, scaffolding, modelling, praise and choice.
Back whole-school systems like check-in/check-out with genuine senior-leadership commitment, applied flexibly to individuals.
