This post is about speech language and communication needs. Original source: Department for Education — Identifying and supporting children and young people with speech, language and communication needs: a rapid evidence review (ref RR1550, September 2025). Research evidence, not statutory guidance.
Speech, language and communication needs (SLCN) are the most common primary need among pupils on SEN support. This DfE-commissioned rapid evidence review, led by UCL, examines how mainstream schools identify and support pupils aged 5 to 25 with SLCN — excluding autism, which is covered by a separate review. Its most useful contribution is a clear, tiered way of thinking about language support that any school can adopt.
Identification depends on interpretation, not just tools
The review found a range of tools for flagging speech, language and communication difficulties early. But the headline is cautionary: accurate interpretation depends on understanding each tool’s reliability, validity and normative benchmarks — which is specialist knowledge. That is why every preliminary assessment should be discussed with the SENCo, families and a speech and language therapist, and why clear role definitions and ongoing professional development in SLCN matter so much.
The point about co-occurring needs is essential. SLCN rarely travels alone; it frequently appears alongside ADHD or literacy difficulty. A pupil who is not responding to reading support may have an underlying language need that has not been named. Effective identification rests on collaborative practice and dynamic assessment that looks at how a child learns, not just a snapshot score.
Support: a tiered model, from universal to specialist
The review recommends the familiar three-tier model. Tier one is high-quality universal classroom teaching for everyone: explicit sequencing of tasks, clear prompts, scaffolding, mnemonics and metacognitive strategies that reduce cognitive load. Tier two is targeted small-group or individual work for those who need more. Tier three is intensive, often one-to-one, specialist-delivered support for those who still have not progressed.
The targeted interventions that work best share three features: they focus on both the meaning and the sounds of language, they use storytelling approaches, and they are delivered by trained staff in one-to-one or small-group settings. Visual story aids, parent-led turn-taking, shared reading and structured lessons all improved storytelling and conversation skills. For speech sounds, movement-based techniques with real-time feedback helped younger children and those with persistent disorders.
Consistency is the multiplier. Reinforcement across home, clinic and classroom, regular progress checks, and a classroom genuinely designed to encourage talk — with lower noise and tools like the Communication Supporting Classroom Observation Tool to audit it — all strengthened outcomes.
The honest gaps
The evidence base has real weaknesses. Most studies use bespoke outcome measures and few follow up long-term, so we know less than we would like about whether gains stick. There is little research on teacher- or teaching-assistant-led delivery, particularly in secondary schools, where language support is often neglected. And inconsistent terminology between education and health settings makes it hard to choose and compare tools.
For school leaders, the practical reading is this: make language-rich universal teaching the default, audit your classroom environments for talk-friendliness, and build a real partnership with your speech and language therapy service — because interpretation, not the tool itself, is where identification succeeds or fails.
The tiering is worth spelling out because it is where most schools go wrong. Tier one is not a warm-up; it is the explicit sequencing of tasks, clear prompts, scaffolding, mnemonics and metacognitive strategies that reduce cognitive load for every learner. A child should only move to tier two when they struggle despite that universal teaching, and to tier three only when small-group support has not closed the gap. The review’s emphasis on both the sounds and the meaning of language is a specific, practical correction to interventions that drill sounds in isolation.
Practical takeaways for schools
- Treat every preliminary assessment as the start of a discussion with the SENCo, families and a speech and language therapist — never a standalone verdict.
- Watch for co-occurring needs: an unexplained reading or attention difficulty can hide an unnamed language need.
- Make language-rich universal teaching the default and audit classrooms with a tool like CSCOT.
- Prefer targeted interventions that focus on both meaning and sounds, use storytelling, and are delivered by trained staff in small groups.
- Reinforce consistently across home, clinic and classroom.
