When to Refer to a Speech Pathologist

At Vibrance Speech Pathology, we support children and young people with communication, speech, language, literacy, and fluency needs.

This page is designed as a quick reference guide for parents, educators, GPs, psychologists, and allied health professionals to help clarify:

when a referral to speech pathology may be appropriate
what speech pathologists support (and what they don’t)
how concerns present across different ages and settings
how to choose the most appropriate next step.

If you are unsure whether to refer, early assessment is always appropriate. Speech pathology input can help clarify whether difficulties are part of typical development or require targeted support.

When to consider a referral

A referral to speech pathology may be appropriate when a child or young person shows ongoing difficulty with:

understanding or using language
being understood by others (speech clarity)
learning to read, spell, or develop literacy skills - even beyond early primary years
producing fluent, connected speech (e.g. stuttering)
communicating effectively across home, school, and social settings
frustration or withdrawal due to communication breakdown.

Concerns can present differently depending on age, environment, and learning demands.

Below are common areas that speech pathologists assess and treat, and when it might be helpful to call one for advice.

Speech Sounds

Consider referral if a child:

is difficult for unfamiliar listeners to understand, particularly beyond the age of 3. As a rule of thumb, children should be about 75% intelligible by unfamiliar listeners at 3 years and 100% intelligible by 4 years.
has ongoing sound errors that are not improving over time
becomes frustrated when not understood
avoids speaking or participating in conversations
shows multiple or inconsistent speech sound errors.

Further information about speech disorders and how speech pathologists can help is available on our Speech Sound Disorders page.

Language Delay

Referral for language assessment is recommended where children aren't meeting age-specific milestones:

By 18 months: Uses fewer than 20 words, cannot follow a simple 1-step direction (e.g. give me the ball)
By 2 years: Uses fewer than 50 words, is not spontaneously combining 2 words (e.g. more milk).
By 3 years: Is not consistently using at least 3 words in a sentence, cannot follow simple 2-step instructions (e.g. get your shoes and put them by the door)
By 4-5 years: Cannot tell a simple story, makes frequent grammatical errors, cannot answer "who, what, where" questions.

Regardless of age, assessment is recommended where other challenges arise including:

Regression of skills
Frustration arising from not being understood
Reduced participation at preschool or school arising from difficulty understanding instructions
Difficulty talking frequently and using language socially (e.g. they can talk at home but preschool/school report that they don't talk in that setting).

Further information about late talkers, language delays, and links to more comprehensive communication milestones are available on our Language Delay page.

Literacy Difficulties

Consider a referral to speech pathology if a child shows ongoing difficulty with literacy skills that is not resolving with classroom instruction or school-based intervention.

A referral may be appropriate if:

literacy difficulties continue despite targeted classroom or small-group intervention
progress is slower than expected over time
there is a persistent gap between verbal ability and written language performance.

We also dig beyond decoding and into comprehension, so a referral might also be indicated where a child:

reads text aloud fluently and accurately, but cannot explain or summarise what they have read
has difficulty answering questions that require inference or deeper understanding
appears to “read words” without meaningful understanding of content.

We also see children with writing difficulties so a referral may be appropriate if a child:

produces very limited or overly simple written responses compared to verbal ability
has difficulty organising ideas into sentences or coherent paragraphs
struggles with sentence structure when spelling/handwriting are not the main issue.

We talk about the differing but complementary roles of speech pathologists, educators and psychologists in diagnosing and addressing literacy difficulties on our Literacy Support page.

Stuttering/ Fluency

Consider referral if a child:

repeats sounds, words, or phrases frequently
prolongs sounds or becomes “stuck” on words
shows tension or effort during speaking, including groping or tics
avoids speaking situations
becomes aware or distressed about their speech.

Early speech pathology assessment is highly recommended, as intervention in the preschool years (typically before age 6) is associated with the best outcomes, with many children achieving significant reduction in stuttering severity and, in some cases, complete remission.

Further information about stuttering and treatment programs available can be found on our Stuttering page.

AAC and Complex Needs

Augmentative & Alternative Communication (AAC) supports enable functional communication where speech is difficult to understand or where verbal speech is not possible.

Consider referral to speech pathology if a child:

is difficult for unfamiliar listeners to understand, or relies on familiar people to interpret their speech
becomes frustrated, withdrawn, or avoids speaking due to communication breakdowns
has speech sound difficulties (including suspected or diagnosed Childhood Apraxia of Speech) that significantly impact intelligibility
has emerging speech but inconsistent ability to communicate messages clearly across settings
would benefit from additional visual or structured communication supports alongside spoken language
requires support to participate more effectively in home, school, or community activities
needs alternative ways to express ideas, needs, or opinions when spoken communication is not reliable across environments.

AAC may include visual supports, communication boards/books, key word signing, or speech-generating devices, and can be used alongside spoken language goals to support participation and communication development.

More information about how speech pathologists trial and implement AAC is available on our Augmentative & Alternative Communication page.

Working together

We regularly work alongside GPs, paediatricians, psychologists, occupational therapists, educators, and support coordinators to support children and families with their communication needs.

Communication difficulties are best understood and supported through a collaborative approach, where each professional contributes their area of expertise.

If you are unsure whether a referral is appropriate, or would like to discuss a case, you are welcome to contact us for informal clinical discussion or guidance.
