Bilingual Evaluation: Language Difference or Disability?
Sofia is a second grader who moved from rural Guatemala 18 months ago. She speaks Spanish at home and has attended school in the U.S. for 15 months; before that her schooling was interrupted and she attended only about one year. Her WIDA ACCESS overall score is 2.0 (emerging). Her teacher refers her for special education because she reverses b/d, confuses letter sounds, does not follow two-step directions, and is quiet in groups. The school psychologist plans to administer an English-language intelligence test and a reading test, with a Spanish-speaking paraeducator translating the instructions. Sofia’s parents speak limited English; the school has not yet provided a Spanish interpreter for meetings. Her attendance is 88%. The student support team wants to “wait until she is fluent” before evaluating. The parents signed consent for evaluation.

The proposed plan is not a valid evaluation of a bilingual child. Standardized intelligence and reading tests normed on English-speaking students, with a paraeducator translating instructions, do not yield valid scores; translation alters standardization and can understate ability. The team also cannot “wait until she is fluent” when a disability is suspected, because delaying evaluation may deny FAPE and is not required by IDEA. The evaluation must assess Sofia in her native language and in English, using measures appropriate for her linguistic and cultural background, and must include a trained bilingual examiner or a qualified interpreter-not a paraeducator assigned without training. The team should gather developmental, medical, and educational history; information about interrupted schooling; classroom observations across settings; work samples in Spanish and English; language-proficiency data; and evidence of response to intervention. Parents must receive interpretation for meetings and documents. If the district lacks qualified staff, it must contract for them. The evaluation should also examine hearing and vision and rule out lack of instruction and cultural difference before eligibility is decided.
2. How should the team distinguish language acquisition from a disability, and what should happen if Sofia is found eligible?

Distinguishing language acquisition from disability requires a pattern analysis, not a single test. Sofia has been in U.S. schools for 15 months, has interrupted prior schooling, and is at WIDA level 2; b/d reversals and quiet group behavior can be typical of emerging bilingualism. The team should compare her progress in Spanish and English, observe her in both languages, and review response to Tier 2 intervention delivered with fidelity in a comprehensible way. A true disability is suggested when difficulties persist across languages and settings, are not explained by opportunity to learn, attendance, or acculturation, and are atypical compared with similar English learners. If Sofia is found eligible, the IEP must address her disability-specific needs while still providing English-learner services; goals should target foundational reading skills, not just English proficiency. The team should include an EL teacher, monitor progress frequently, and guard against overrepresentation. If she is not eligible, the team should still provide targeted language and literacy support and set a date to review data.
