AbilityScore 300–400 with DLD: your next steps

An AbilityScore in the 300–400 band is not a verdict — it's a starting line, and you're already on it. Here's what to do with that number.

In short

Your child's AbilityScore® is a clinician-administered baseline — a structured snapshot of where their language sits today, measured against their own starting point rather than against other children. A 300–400 band tells your speech-language pathologist where to begin and what to prioritise; it is not a ceiling and not a label. The next step is simple: turn that baseline into a personalised therapy plan, start consistent intervention, and re-measure on schedule so progress becomes visible.

What to do next, in order

• Sit down for the plan review. Your clinician translates the baseline into specific, child-sized goals — comprehension, expressive vocabulary, sentence-building, and using language socially — in the order that helps your child most.
• Begin consistent speech and language therapy. With Developmental Language Disorder, regular, structured, play-based practice is what moves language forward. Consistency matters more than intensity in any single week.
• Carry therapy into the home. Ten minutes of back-and-forth talk daily — narrating routines, pausing for your child to fill the gap, celebrating every attempt — multiplies what happens in the therapy room.
• Re-measure on schedule. The same structured assessment, repeated, shows movement against your child's own earlier band — so even quiet, steady progress is captured rather than guessed.

The science, briefly

DLD affects roughly 7% of children — about two in a typical classroom — and these children are often bright and socially warm, which is exactly why it can be under-recognised. The WHO classifies it within developmental language disorders (ICD-11 6A01.2), and international expert consensus (CATALISE) defined it so it would stop being missed. With early, consistent therapy, language and confidence improve markedly, and most children go on to thrive in mainstream classrooms.
