Developmental language disorder (DLD) affects how children understand and use language. It's common, lifelong, and highly responsive to speech therapy.

What developmental language disorder is
Developmental language disorder (DLD) is a common, lifelong condition where a child has significant, ongoing difficulty understanding and/or using language — without another condition (like hearing loss, intellectual disability, or autism) accounting for it.[] The international CATALISE consensus settled on the term DLD in 2017 to replace a confusing patchwork of older labels.[]
It's far more common than most parents realise — roughly one child in every classroom — yet it's much less recognised than conditions like autism or ADHD, partly because it's invisible: a child with DLD can look like they're "just quiet," "not trying," or "behind."
What it looks like
DLD shows up across understanding (receptive language) and use (expressive language):
- Trouble following instructions, especially multi-step ones
- A smaller vocabulary than peers; word-finding difficulty ("you know, that thing")
- Grammar that stays immature — muddled tenses, plurals, sentence structure
- Difficulty telling or following a story in order
- Conversations that break down — missing the point, going off-track
- Frustration, withdrawal, or behaviour that's really a communication problem underneath
Because language underpins reading, learning, and friendships, unaddressed DLD tends to ripple into literacy and wellbeing over time.
How speech therapy helps
DLD is one of the most therapy-responsive communication conditions. Systematic reviews show speech and language therapy produces clear short-term gains — strongest for expressive vocabulary and grammar, with early, intensive intervention giving the best results.[] Speech pathology for DLD typically blends:
- Direct language work — building vocabulary, grammar, and sentence structure at the child's level
- Comprehension strategies — tools for following instructions and understanding what's asked
- Narrative skills — learning to tell and follow stories, which underpins both conversation and writing
- Parent and teacher coaching — so the language-rich strategies carry into home and classroom, where most learning happens
For younger children much of the work is delivered through the parent; for school-aged kids it blends direct sessions with practical carryover.
NDIS funding for DLD
DLD can meet NDIS access criteria when it's permanent and substantially affects communication and daily life.[] Families commonly submit a speech pathologist's assessment alongside the RADLD fact sheet to support an access request.[] If approved, speech therapy is typically funded under Capacity Building — Improved Daily Living. For families without NDIS funding, sessions are private-pay at the NDIS rate.
What a Hey Sprout session looks like
Sessions run online via secure video. For younger children, parents are in the room and coached to weave language strategies into everyday routines; for older kids, sessions are more direct with planned parent check-ins. We hold your preferred slot before asking for any NDIS or plan-manager details.
Frequently asked questions
What's the difference between a language delay and a language disorder?
A delay means a child is following the typical pattern of language development, just later — and often catches up. A disorder (DLD) means language develops differently and the difficulties persist, affecting everyday understanding and expression. A speech pathologist can assess which one fits, and the plan is different for each.
Is DLD the same as a speech sound problem?
No. Speech sound difficulties are about how clearly a child pronounces words. DLD is about understanding and using language — vocabulary, grammar, following instructions, telling a story, holding a conversation. A child can have one, the other, or both.
Does DLD qualify for NDIS funding?
DLD can meet NDIS access criteria when it's permanent and substantially affects communication and daily functioning. The RADLD fact sheet and a speech pathologist's assessment are commonly used to support an access request. We can help you assemble the evidence.
Will my child grow out of it?
DLD is lifelong, but that doesn't mean it can't improve. With the right support children build strategies and skills that make a real difference to school, friendships, and confidence — and the earlier therapy starts, the better the trajectory.
Does Hey Sprout diagnose DLD?
Our speech pathologists assess language and can identify DLD as part of therapy. A standardised language assessment is part of that process. If a broader developmental assessment is needed, we'll help you sequence the right appointments.

Related conditions
Autism (Level 1 and Level 2) in children
Autism is a lifelong neurodevelopmental difference. Level 1 and Level 2 children typically benefit from speech, OT, and psychology support — and most are NDIS-eligible.
Cerebral palsy — therapy support for children
Cerebral palsy affects movement and posture. Goal-directed OT and speech therapy build independence and communication, online and coordinated with your team.
Childhood apraxia of speech (CAS)
CAS is a motor speech disorder where the brain struggles to plan the movements for speech. It needs frequent, specific speech therapy — and responds to it.
Down syndrome — therapy support for children
Children with Down syndrome thrive with early, consistent therapy. Speech and OT build communication and daily-living skills, online and parent-coached.
