How Developmental Language Disorder Is Assessed Under 7
DLD in children under 7 is assessed by a speech-language therapist through structured observation, parent history, a hearing check, and age-appropriate standardised measures of understanding and expression. Diagnosis is considered when difficulties are persistent, affect daily life, and aren't explained by another cause. Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional.

When a child's words come slower than expected, the first step isn't a label — it's a careful, child-friendly look at how language is really working.
In short
For children under 7, Developmental Language Disorder (DLD) is assessed through a structured, clinician-led process — never a single test. A speech-language therapist observes how your child understands and uses language during play and conversation, uses age-appropriate standardised language measures, and gathers your family's history and a hearing check. The aim is to see whether language difficulties are persistent, affect everyday life, and are not better explained by hearing loss, another condition or a temporary delay.
What assessment looks like
A thorough DLD assessment in the early years brings together several strands:
- Parent and developmental history — how your child babbled, gestured, said first words, and joins words now.
- Hearing screen — always ruled in or out first, because glue ear and hearing loss can mimic language delay.
- Receptive language — does your child understand instructions, questions and stories?
- Expressive language — vocabulary, sentence length, grammar and how they tell you things.
- Play and social communication — observed naturally, to see language in real use.
- Standardised measures — chosen for your child's age, comparing skills to typical milestones.
Diagnosis is considered when difficulties are persistent, impact daily learning and relationships, and aren't explained by another cause. For under-7s, clinicians also weigh whether to monitor closely versus assess fully, as language is still rapidly emerging.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch whether your child understands simple instructions, joins words into short phrases by age two, and is understood by family — and whether these lag behind peers across home and nursery, not just on a hard day.
In everyday life
Talk through everyday routines out loud — naming actions and objects as you go. Rich, unhurried conversation gives your child more chances to hear and try language.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Is one test enough to diagnose DLD?
No. DLD is assessed through a combination of parent history, a hearing check, observation of language in play, and age-appropriate standardised measures — never a single test.
Why is a hearing check part of the assessment?
Hearing problems like glue ear can look like a language delay. Ruling hearing in or out first makes sure the assessment is accurate.
Can DLD be diagnosed before age 7?
Yes, when language difficulties are persistent, affect daily life and aren't explained by another cause. For very young children, clinicians may monitor closely as language is still emerging.
