Speech and Language Norms for Age 6

Quick reference — age 6 norms

Values are central estimates. Individual variation is wide — a child who falls a little outside the typical range is not automatically delayed. Use these as one input alongside direct assessment.

Clinical guidance

At 6 the caseload question becomes "does the child still qualify?" for children with early-intervention history. Sentence-level metrics (MLU, PGU) often look typical even when the child is falling behind peers in narrative and reading — this is the classic late-identified language disorder profile. The SLP role at this age is to connect language-sample data to classroom performance: if narrative is weak, the child's reading comprehension in second grade is predictably weak. Dynamic assessment works especially well at this age because the child has the metalinguistic skill to benefit from modeling. A good practice is to pair a 15-minute story-retell sample with a brief reading-comprehension probe — the two together catch most children the standardised tests miss.

Red flags at age 6

The items below warrant a referral to a speech-language pathologist for a full evaluation. Any single item is enough to justify a conversation — do not wait for multiple flags to stack up.

• ⚠MLU below 4.5 morphemes
• ⚠Frequent word-finding pauses and circumlocutions in connected speech
• ⚠Cannot retell a recently read story with a clear main idea
• ⚠Simple subject-verb-object sentences only, no subordination
• ⚠Any phonological process remaining
