Deciding Whether a Behavior Is a Developmental Delay or a Language Difference
You teach in a pre-K classroom of 18 four-year-olds. One child, Mateo, moved from Guatemala six months ago. He speaks Spanish at home and uses about 15 English words spontaneously, mostly nouns. He follows one-step directions given with gestures, points and pulls your hand to request, and rarely initiates with peers. During small-group story time he sits quietly and watches. His mother reports that at home he talks in full Spanish sentences, tells stories, and argues with his older sister. A colleague suggests referring him for special education evaluation now, saying 'six months is long enough.' You have a screening tool available in both languages and a bilingual interpreter who visits the building twice a month.
1. Should you refer Mateo for special education evaluation immediately? Justify your decision using developmental and second-language-acquisition reasoning.

No-an immediate referral is not warranted on this evidence. Key reasoning:
- Home-language competence is intact. Full sentences, storytelling, and negotiation in Spanish rule out a global language disorder; a true language impairment would show up in the first language too.
- Silent period and transfer are normal. Six months of English exposure with ~15 spontaneous words is within the expected range for sequential bilingual preschoolers. Receptive skills (following directions with gesture support) are ahead of expressive English, which is typical.
- Language difference vs. disorder. The pattern (strong L1, weak L2, gesture-supported comprehension) points to a difference, not a disability.
- But do not simply wait passively. Use the bilingual screener, document observations across settings, and consult the interpreter to gather parent-report data in Spanish. If screening flags concerns in the home language or if progress stalls after targeted support, then refer.
- Caution against the colleague's logic. 'Six months is long enough' ignores that typical second-language learners need years, not months, to reach age-level proficiency.
2. Describe two classroom supports you would put in place over the next 6–8 weeks and how you would use data to decide whether to refer.

Supports:
- Bilingual and visual scaffolds-label key areas in Spanish and English, use picture schedules, pair Mateo with a Spanish-speaking peer for routines, and model English in predictable repeated phrases during play.
- Structured peer interaction-engineer small-group play with scripts and props (e.g., pretend restaurant) so requesting and turn-taking have low linguistic demand and high repetition.
Data-based decision:
- Collect weekly running records of spontaneous English utterances, initiations with peers, and response to directions without gestures.
- Administer the bilingual screener now and again at 8 weeks; compare growth in both languages.
- Share data with the interpreter and family at a conference.
- Decision rule: if home-language skills remain strong and English shows steady upward growth, continue support. If concerns appear in both languages, or growth is flat despite consistent support, initiate a referral with the documented data.
