Speech Sounds & Speech Clarity

Speech clarity determines how much of a child's thinking the school ever sees. Where clarity is quietly treated as a proxy for ability, children are placed in lower groups, asked fewer questions and given less demanding work — a slow, invisible loss that no single lesson observation will show.

Bercow: Ten Years On found identification and provision for speech, language and communication needs in England to be highly variable, with communication too often treated as a specialist add-on rather than everybody's business. That framing is a leadership decision.

Most staff have had little or no training on speech, language and communication. A short, well-chosen set of practices is more likely to embed than a long list.

• The difference between speech, speech sounds, language and communication — and why it changes what you do.
• Model, do not correct: what recasting sounds like in a real lesson.
• What to do when you cannot understand a child, agreed word for word across the school.
• How to record what you notice so it is useful to a therapist.
• Why unclear speech should not be used as evidence of ability, effort or behaviour.

• Consistency of agreed practice observed across classes and across non-teaching adults.
• Participation of identified children in spoken work, not just their attainment.
• Timeliness of referrals and quality of the information school sends.
• Whether adjustments survive staff absence and transition to the next year group.
• Family feedback on whether they feel heard when they raise concerns.

1. Royal College of Speech and Language TherapistsProfessional guidance
   Speech sound disorders — clinical guidance (updated 2024)

   The UK professional reference point. Explains that 'speech sound disorder' is an umbrella term used when a child's speech is much harder to understand than other children of the same age speaking the same language, and that sub-types differ in cause and in what helps.

2. Royal College of Speech and Language TherapistsProfessional guidance
   Position paper on Childhood Apraxia of Speech (CAS) (2024)

   Relevant only to a small minority of children. Useful for understanding why a few children need specialist, high-frequency motor-speech input rather than general classroom support.

3. Speech and Language UKProfessional guidance
   Speech sounds (resource library for educators)

   Plain-English explanation for school staff, including the point that speech sounds are not letters — 'sheep' has five letters and three sounds.

4. Speech and Language UKProfessional guidance
   Ages and stages

   Typical development by age band, with the standing caveat that children reach these stages at different rates. Use as a reference point, never as a checklist to score a child against.

5. NHS (Berkshire Healthcare NHS Foundation Trust)Professional guidance
   Typical speech sound development

   NHS speech and language therapy advice on the order sounds usually emerge — early sounds such as b, m, d before later ones such as 'ch', 'th' and clusters. Local NHS services publish similar pages; referral routes vary by area.

6. NHSProfessional guidance
   Glue ear

   Common in young children and can affect hearing while it lasts. One reason a hearing check is a sensible first step when speech is unclear.

7. Department for EducationStatutory guidance
   SEND Code of Practice: 0 to 25 years (2015)

   Places speech, language and communication within the communication and interaction area of need, and sets out the graduated approach — assess, plan, do, review — schools must follow.

8. Department for EducationStatutory guidance
   Early years foundation stage statutory framework (current version)

   Communication and language is a prime area; settings must provide a language-rich environment and back-and-forth interaction.

9. Department for EducationProfessional guidance
   The reading framework: teaching the foundations of literacy (2021, updated 2023)

   Relevant because phonics teaching and assessment rest on hearing and producing sounds. It sets out how to teach and check phoneme–grapheme correspondence, which is where unclear speech can be misread as a phonics gap.

10. Education Endowment FoundationResearch summary
    Preparing for Literacy: improving communication, language and literacy in the early years (2018)

    Recommends high-quality adult–child interaction and developing children's speech, language and communication. It is about the language environment, not about treating speech sound difficulties — that sits with speech and language therapy.

11. Education Endowment FoundationResearch summary
    Improving Literacy in Key Stage 1 (2017, updated)

    Places phonological awareness and language capability among the foundations of early reading and writing.

12. I CAN and RCSLTResearch summary
    Bercow: Ten Years On — an independent review of provision for children and young people with SLCN in England (2018)

    Documents variable identification and long waits for speech and language therapy in England, and argues for communication being everybody's business rather than a specialist add-on.
