Speech and language delay — branching viva

Stem

A 24-month-old is referred because childcare staff cannot understand him and he uses few words. The examiner starts with definitions, then adds complications. [1]

Branch 1 — Definitions

Examiner: What is the difference between speech delay and language delay? [1]

Strong answer: Speech is the production of sounds — articulation, phonology, voice, fluency. Language is comprehension and expression of meaning. A child may have unclear speech with good language, or clear speech with limited language. I also separate social communication — how language is used with people. [1]

Examiner: What is DLD? [4]

Strong answer: Developmental language disorder is the CATALISE consensus term for persistent language difficulties that affect function. It improves on inconsistent older labels. If language problems are part of autism or hearing loss, I describe them in that context rather than forcing an isolated label. [4]

Branch 2 — First assessment

Examiner: What must you not skip today? [1] [2]

Strong answer: Red-flag screen for regression and global issues; formal hearing assessment; classify pattern by history and observation; plan concurrent SLP referral and early supports; safety-net. I will not rely on clapping behind the child as a hearing test. [1] [2] [7]

Branch 3 — Autism fork

Examiner: He does not point to share interest and rarely makes eye contact. Now what? [11]

Strong answer: This is no longer a pure late-talker lane. I keep hearing and SLP pathways, and I add autism-specific screening and referral for comprehensive evaluation. Word count alone cannot exclude autism. [7] [11]

Branch 4 — Guidelines challenge

Examiner: USPSTF says evidence is insufficient for universal speech-language screening tools. Does that mean you do nothing? [9]

Strong answer: No. An I statement about universal asymptomatic instrument screening does not cancel concern-driven evaluation, failed surveillance items, or functional delay. AAP-style surveillance and action on concern still apply. [7] [9]

Branch 5 — Systems

Examiner: SLP waitlist is nine months. What do you do? [13]

Strong answer: I still refer, escalate urgency with clinical detail, start parent-mediated language strategies now, involve early intervention if eligible, consider telehealth options, and book interim medical review so the loop is not open. Care coordination is part of treatment. [13]

Closing pearl

Examiner: Give me your one-line plan. [1]

Strong answer: Hearing, pattern, parallel pathway, closed loop — never reassurance alone. [1] [7]
