Key facts

What a speech and language assessment is, in six facts.

The essentials - what the session is, who runs it, how long, and what you leave with.

  • Definition

    SLT-led structured speech and language assessment.

  • Duration

    60–90 minute session.

  • Clinician

    HCPC-registered speech and language therapist.

  • Pathways

    Child and adult pathways available.

  • Tools used

    Standardised assessment tools (CELF, WAB).

  • What you get

    Structured therapy plan with defined goals.

The problem

An SLT assessment is only useful if it comes with a plan.

A description of the problem is not the answer. An HCPC-registered SLT who runs standardised tools and writes a plan you can act on is the right person to see.

  • Post-stroke aphasia, dysarthria or dysphagia?

    An adult SLT with the relevant subspecialty and MDT links is usually the right route.

Assessment steps

How an SLT reaches an answer.

The steps most SLT assessments follow - history, standardised tools, physical exam, voice and fluency, then plan.

  1. 01

    SLT consultation

    Introductions and the presenting concern - from you, or from a parent or carer.

  2. 02

    Case history + parental / carer report

    Developmental history, previous reports, school or MDT input, medications and relevant medical history.

  3. 03

    Standardised assessment tools

    Validated instruments - CELF for language in children, WAB for aphasia in adults, and others as needed.

  4. 04

    Oro-motor examination

    Lips, tongue, palate and swallow function - the physical apparatus behind speech.

  5. 05

    Voice + fluency assessment

    Vocal quality, pitch, stamina and - where relevant - stammering / stuttering patterns.

  6. 06

    Structured report

    A clear written report - findings, interpretation, and what they mean.

  7. 07

    Personalised therapy plan

    Defined goals, therapy frequency, home-practice tasks and review points.

What it shows

When a speech and language assessment is the right first step.

SLT assessment answers a specific question - where the communication or swallow difficulty sits, and what to do about it. These are the most common presentations.

  • Delayed language development

    Expressive or receptive language behind expected milestones in children.

  • Speech sound disorder

    Articulation and phonological difficulties affecting intelligibility.

  • Stammering / stuttering

    Fluency disruption - repetitions, prolongations, blocks - in children and adults.

  • Post-stroke aphasia

    Loss of language after stroke - expressive, receptive or global.

  • Dysarthria (Parkinson’s, MS)

    Weakness or in-coordination of the speech muscles from a neurological cause.

  • Dysphagia

    Swallowing difficulty - assessment and safe-swallow guidance.

  • Voice disorder (dysphonia)

    Hoarseness, vocal fatigue or altered vocal quality.

  • Red flag: rapid post-stroke deterioration - urgent stroke team

    Sudden worsening of speech, weakness or swallow post-stroke is a 999 call, not a private appointment.

Treatment options

What follows the assessment.

The therapy pathways your plan may draw on - from individual sessions to intensive programmes and MDT review.

  • Individual SLT therapy

    One-to-one sessions targeting the specific goals in your therapy plan.

  • Group therapy programmes

    Peer-based practice - fluency, aphasia and social communication groups.

  • LSVT LOUD (Parkinson’s)

    Intensive evidence-based voice programme for hypophonia in Parkinson’s.

  • Voice therapy (dysphonia)

    Vocal function exercises, resonant voice therapy and vocal hygiene.

  • Swallowing rehabilitation

    Exercises, postural strategies and diet modification for dysphagia.

  • Augmentative and alternative communication (AAC)

    Low- and high-tech tools when speech alone isn’t enough.

  • Structured SLT follow-up

    Scheduled review sessions with objective outcome measures.

  • Multi-disciplinary team review

    Joint working with ENT, neurology, paediatrics or the stroke team as needed.

Red flags

When SLT assessment isn’t the first thing to book.

Some presentations need urgent medical review - or a specific joint pathway - before or alongside SLT. Here are the ones that matter.

  • Rapid post-stroke deterioration

    Sudden worsening of speech, swallow or weakness after a stroke is a 999 call.

  • Silent aspiration on dysphagia assessment

    Aspiration without a cough is high-risk - needs urgent instrumental swallow assessment.

  • Post-radiotherapy dysphagia

    New swallowing difficulty after head-and-neck radiotherapy needs prompt review.

  • Vocal cord palsy

    Persistent hoarseness with a suspected palsy needs ENT and imaging alongside SLT.

  • Head-and-neck cancer with dysphagia

    Swallowing symptoms in the context of head-and-neck cancer - joint SLT and oncology review.

  • Motor neurone disease

    Progressive bulbar symptoms - early SLT input with neurology co-management.

  • Progressive aphasia

    Insidious language decline in an adult - needs neurology and cognitive work-up.

  • Autism spectrum disorder + regression

    Loss of previously acquired language in a child - urgent paediatric review.

  • Selective mutism

    A child who speaks freely at home but not in certain settings - specialist pathway.

Reading your report

An SLT report can look dense. It isn’t.

Whatever the finding, the report keeps to the same four parts.

A quiet reminder

The report is written for the wider clinical team too - and that’s normal.

If you would like your SLT to talk you through it, just ask.

  1. 01 Header

    Presenting concern and history

    Your details, the reason for assessment, and the developmental or medical history that shapes interpretation.

  2. 02 Assessment

    Standardised tools and clinical observation

    Which instruments were used (CELF, WAB, others), oro-motor findings, and voice / fluency observations.

  3. 03 Findings

    Scores, profile and interpretation

    Standardised scores, a plain-English profile, and what the pattern means clinically.

  4. 04 Plan

    Goals, therapy and review

    A personalised therapy plan with defined goals, frequency, home tasks and review points.

Frequently asked

Common questions about SLT assessment.

Quick answers on what it is, which tools are used, how long it takes, and what happens afterwards.

  • What is a speech and language assessment?

    A structured session led by an HCPC-registered speech and language therapist (SLT) to evaluate speech, language, voice, fluency and - where relevant - swallowing. It uses standardised tools alongside clinical observation and produces a written report with a therapy plan.

  • What standardised tools do you use?

    For children, the CELF (Clinical Evaluation of Language Fundamentals) is a common core tool alongside articulation and phonology batteries. For adults with aphasia, the WAB (Western Aphasia Battery) is widely used. Selection depends on the presenting concern.

  • How long does the assessment take?

    Typically 60–90 minutes for the session itself, with the structured written report and therapy plan sent afterwards - usually within a week.

  • Do I need a referral?

    Most clinics accept self-referral.

  • What happens after the assessment?

    You receive a written report and a personalised therapy plan with defined goals. Onward pathways - individual therapy, group programmes, LSVT LOUD, voice therapy, swallowing rehab or AAC - are arranged from there, with MDT review where indicated.

In practice, in London

Where speech and language assessment sits in a private London pathway

With speech and language assessment, the London question is usually about report turnaround and the radiologist reading it - not whether the scan is available. Public provision for speech and language assessment is competent but constrained by capacity. Private London clinics tend to have shorter diaries and longer appointment slots, so you get the same specialists with more time. For people who’ve been going round in circles with primary care, that first proper conversation is often what shifts things.

A private speech and language assessment pathway in London usually looks like this: an initial consultation, any diagnostics booked at a nearby facility (most within Zone 1 or 2), and a written report sent to you and your GP within a few days. For speech and language assessment specifically, the difference between a routine report and a sub-speciality read is where private care earns its keep.

There are a lot of consultants in London who can technically handle speech and language assessment. Fewer who do it week in, week out for the exact question you’re bringing. It is worth asking how often the clinician does this assessment, and whether a different test or a different specialist would serve you better.
