Speech and language concerns in children (Paediatric speech, language and communication assessment)
An assessment of how a child understands and uses language, talks and communicates, to find out whether they have a delay or difficulty and what support could help.

In short
- The assessment works out whether a child's communication is developing within the normal range, is delayed, or shows a more persistent difficulty — and what would help.
- Children vary widely, and many 'late talkers' catch up; the assessment helps tell ordinary variation from a difficulty that needs support.
- A hearing check is often part of the picture, because hearing problems (including after ear infections) are a common and treatable cause of communication delay.
- Speech and language difficulties can be linked to wider development (such as autism), so a good assessment looks at the whole child — and early support helps.

What is a speech and language assessment for a child?
A speech and language assessment is a careful look at how a child communicates — how much they understand, how they use words and sentences, how clearly they make speech sounds, and how they interact with others. It is carried out by a speech and language therapist (SLT), mostly through play, talking and watching the child, alongside questions to parents.
Children develop communication at different rates, and a lot of variation is completely normal. Some children are simply 'late talkers' who catch up. Others have a more persistent difficulty, such as a developmental language disorder (DLD), or trouble making certain speech sounds. The assessment helps tell these apart and works out what, if anything, would help.
It is important to know that speech and language difficulties are sometimes a sign of something else — for example a hearing problem, or part of a wider developmental picture such as autism or global developmental delay. A good assessment considers these possibilities and arranges a hearing check where needed.
The aim is not to label a child but to understand them, reassure where development is on track, and offer practical support and therapy where it will help. Early support can make a real difference, and a great deal can be done by helping families and nurseries support communication day to day.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
Options at a glance
These are the main approaches described in this guide. The right option depends on the diagnosis, your goals and what your clinician thinks is safe.
Understanding (receptive language)
How well a child understands words, instructions and questions. Understanding usually develops ahead of talking, and difficulties here are important to pick up.
Using language (expressive language)
How a child uses words and joins them into sentences to express themselves. This includes vocabulary, grammar and the ability to tell you things.
Speech sounds (clarity)
How clearly a child pronounces sounds and words. Some unclear speech is normal in young children; persistent or unusual patterns may need help.
Social communication and interaction
How a child uses communication with others — eye contact, gestures, pointing, taking turns and responding. Differences here may point towards a wider assessment.
Preparing for your test
- Note when you first had concerns and what they are — understanding, talking, clarity, interaction, or stammering.
- Write down roughly what your child can do: how many words, whether they join words, whether they follow instructions, and how they communicate without words (pointing, gestures).
- Note any history of ear infections, glue ear or hearing concerns, as hearing strongly affects speech and language.
- Bring details of pregnancy and birth, developmental milestones (sitting, walking), family history of speech, language or learning difficulties, and the languages spoken at home.
- Bring any reports from nursery, school, the health visitor or other professionals.
- Bring a favourite toy or book; assessments are play-based and your child being relaxed helps.
- Note any concerns about how your child plays, makes eye contact or interacts socially.
What happens
The therapist will spend time playing and chatting with your child to see how they understand and use language and how they communicate. Much of the assessment looks like play, because that is how children show their real abilities. The therapist may use toys, pictures and simple structured activities.
They will ask you detailed questions about your child's development, health, hearing, and the languages spoken at home, and about your specific concerns. For children growing up with more than one language, the therapist will look at communication across all of them, since being bilingual does not cause language difficulty.
Afterwards, the therapist explains what they have found — whether development is within the normal range, delayed, or showing a particular difficulty — and discusses a plan. This might be reassurance and advice, strategies for home and nursery, a hearing check, a course of therapy, or referral for a wider developmental assessment. A written report usually follows.
Is this test right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- An assessment of speech alone is the wrong starting point if a child has not had hearing checked — hearing should be assessed where there is any concern.
- A speech and language assessment is not a substitute for a full developmental or autism assessment when there are wider concerns about interaction, play or behaviour.
- Reassurance based on a single short session may be premature for a child who did not engage; a further session or review may be needed.
- Blaming a delay on bilingualism is never appropriate, as being bilingual does not cause language difficulty.
Delay or rearrange if…
- An unsettled or unwell child who cannot engage may need the session rescheduled.
- If hearing has not been checked, arranging this first may give a more meaningful assessment.
- Recent major changes (a new baby, house move, starting nursery) can temporarily affect communication and may be worth noting.
- Do not delay seeking advice if a child is losing skills they previously had — this needs prompt assessment.
Alternatives to discuss
- Watchful waiting with home support for a young 'late talker' with no other concerns
- A hearing test as a first or parallel step
- Home and nursery communication strategies before or alongside formal therapy
- Referral for a wider developmental or autism assessment if interaction is a concern
- NHS speech and language therapy pathway via health visitor, GP, nursery or self-referral
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Benefits
- Clarifies whether a child's communication is developing typically, is delayed, or needs support
- Identifies treatable causes such as hearing problems early
- Provides practical strategies parents and nurseries can use straight away
- Flags when a wider developmental assessment (for example for autism) may be helpful
- Reduces worry by giving a clear understanding of the child and a plan
- Supports access to help at nursery or school where appropriate
Risks & complications
- A child not showing their full abilities in an unfamiliar setting, so impressions may need checking over time
- Some uncertainty: development is a moving picture and a single assessment is a snapshot
- Parents feeling worried or upset hearing that their child has a difficulty
- Needing more than one session, or a hearing test, before a clear view is possible
- A label or report being interpreted too rigidly by others, rather than as a guide to support
- Differences in findings between settings (home, nursery, clinic)
- A communication difficulty turning out to be the first sign of a wider condition that needs its own assessment
- Over-diagnosis or under-diagnosis if bilingual development or normal variation is not properly accounted for
The main uncertainty is that children develop at different rates and a single assessment is a snapshot. Some children labelled 'delayed' catch up, while a few with a more persistent difficulty (such as DLD) need longer support. Because hearing and wider development matter so much, ask whether your child's hearing has been checked and whether their play, interaction and other skills look in keeping with their age. Being bilingual is not a cause of language difficulty and should never be blamed for it.
Published figures to discuss
Communication development varies enormously between children, so it is not meaningful to attach precise percentages to whether a particular child has a difficulty or will 'catch up'. Some late talkers resolve without intervention; others have a persistent difficulty such as developmental language disorder. Because the picture is individual and changes with age, this assessment is about careful, repeated judgement and support rather than fixed figures, and we have not stated invented rates.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Hearing problem contributing to speech delay | Common enough to check early | Glue ear or hearing loss can look like inattention or language delay and should not be missed. | Guide sourcesClinical context |
| Late talking with normal later development | Recognised | Some children catch up, but this should not be used to dismiss clear delay, regression or social-communication concerns. | Guide sourcesClinical context |
| Developmental or autism-related communication difficulty | Recognised | Social communication, play, gestures, understanding and regression matter, not just number of words. | Guide sourcesClinical context |
| Delay to speech and language therapy | Clinically important | Early practical advice and referral can help while broader developmental assessment continues. | Guide sourcesClinical context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
There is no physical recovery from a speech and language assessment. 'Afterwards' is about understanding the findings, starting any recommended strategies or therapy, and knowing what to watch for and when to review.
- Wide variation between children of the same age in how much they talk
- Young children pronouncing many words unclearly, which is normal and improves with age
- Understanding being ahead of talking
- A bilingual child mixing languages or appearing 'quieter' in one language while learning both
- Steady progress with everyday support, rather than sudden change
Aftercare
- Talk, read, sing and play with your child often; everyday interaction is one of the most powerful supports for communication.
- Follow any specific strategies the therapist suggests, such as giving time to respond, modelling words, or reducing background noise.
- Arrange a hearing test if recommended, and treat ear problems such as glue ear.
- Share the report and strategies with nursery or school so support is consistent.
- Keep any therapy appointments and practise suggested activities at home.
- Watch for signs that might need a wider assessment, such as concerns about interaction or play.
- Go back if you feel progress has stalled or new concerns arise.
- The written report and recommended strategies
- A hearing test booked if advised
- Nursery or school informed and given the strategies
- Any therapy sessions scheduled
- A simple plan for daily talking, reading and play
- A note of when the next review will be
- Contact details for questions or new concerns
⚠ Get urgent help if…
- Your child seems not to hear well, does not respond to their name or to sounds, or has frequent ear infections or glue ear
- Your child is losing skills they previously had, such as words they used to say or interaction they used to do — seek prompt advice
- By around 18 months your child is not babbling, using gestures, or pointing to show you things
- By around 2 years your child uses very few words, or does not understand simple instructions
- You have concerns about eye contact, play, or how your child interacts socially as well as their talking
- Your child becomes very frustrated, withdrawn or distressed because they cannot communicate
- Any difficulty swallowing, persistent drooling, or a voice that is persistently hoarse
Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

Results & realistic expectations
A 'good' result is a clear understanding of your child's communication — often reassurance that development is within the normal range, or a clear picture of a delay or difficulty with a plan to support it. The assessment cannot perfectly predict the future, because young children change, but it gives a sound basis for support and review.
For many children, the most useful outcome is practical: strategies for home and nursery, a hearing check if needed, and a plan to monitor progress. Where a more persistent difficulty such as DLD is identified, the result helps secure the right longer-term support.
An assessment reflects your child's communication at one point in time. Because development continues and can change quickly in early childhood, findings are reviewed and the plan updated as your child grows. Some children need only short-term support; others, such as those with developmental language disorder, benefit from support over a longer period.
Related tests, treatments or support
A speech and language assessment is often combined with a hearing test, and sometimes with a wider developmental assessment if there are concerns about play, interaction or other skills. It may form part of an autism or global developmental delay assessment, since communication is a key area in both.
Follow-up & long-term care
Follow-up depends on the findings: some children are discharged with advice, others have therapy and review, and some are referred on for a hearing or developmental assessment. You should be told the plan, who is responsible for it, and how to get back in touch if progress stalls or concerns grow.
- Keep up everyday talking, reading, singing and play, which support communication long term
- Treat ear and hearing problems promptly, as these affect speech and language
- Keep nursery or school informed so support stays consistent
- Return for review if progress slows or new concerns arise
Repeat, follow-on and what comes next
- A young child's communication is reassessed over time, and the plan is adjusted as they develop.
- Initial impressions may change once a child engages more, or once a hearing problem is treated.
- Some children need a single assessment and advice; others need ongoing review and support.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- A clear written report explaining the findings and the recommended plan
- Practical strategies for home and nursery, not just clinic sessions
- A hearing check arranged where relevant
- A defined review point to reassess progress
- A named contact and a clear route back if progress stalls or new concerns arise
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- The length of the assessment and whether more than one session is needed
- Whether a hearing test or other tests are included
- The complexity of the report required (for example for school or an EHC needs assessment)
- Whether standardised assessment tools are used
- Whether follow-up therapy sessions are part of the package
- Whether the therapist liaises with nursery, school or other professionals
- The therapist's fee for the assessment
- Whether a written report is included and how detailed it will be
- The cost of any hearing test or additional assessments
- What is included if further sessions or therapy are needed
- Whether liaison with nursery or school is included
- What happens, and what it costs, if onward referral (for example for autism assessment) is recommended
On the NHS? NHS speech and language therapy assessment is available, usually by referral or self-referral, but waiting times vary by area; some families use private speech and language therapists for a quicker assessment or second opinion.
You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.
Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Not checking or asking about hearing before concluding the cause of a delay
- Treating a one-off assessment as a fixed lifelong label rather than a guide to support
- Overlooking wider developmental or interaction concerns
- Attributing difficulties to bilingualism without proper assessment across all the child's languages
- Not explaining who will see the report, especially where it affects school support
Marketing red flags
- Promises of a quick 'fix' for speech with a fixed number of paid sessions regardless of need
- A label or diagnosis offered after a very brief assessment without considering hearing or wider development
- Discouraging the free NHS speech and language therapy pathway
- Claims that an app or product alone will resolve a genuine language difficulty
- No clear plan for review, or for liaising with nursery and school
Choosing a specialist safely
- Check the specialist is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good specialist will welcome every one of these.
- Is my child's understanding, talking, speech clarity or interaction the main concern?
- Has my child's hearing been checked, and should it be?
- Is this likely to be a delay my child will catch up from, or a more persistent difficulty?
- Do you have any concerns about my child's wider development or interaction?
- What specific strategies can I use at home and at nursery?
- When will we review progress, and what would mean we should come back sooner?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the specialist who carries out my test, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this test not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
