Multilingual development changes the assessment question
The clinician is not asking whether the child performs like a monolingual speaker in each language. The question is whether patterns are consistent with the child’s language-learning history or indicate a disorder affecting the underlying language system. Transfer, code-switching, language dominance, attrition, dialect, and uneven opportunity are expected considerations—not automatic symptoms.
Build a detailed language history
Document when each language was introduced, who uses it, in which activities, how often, changes in exposure, education language, dialects, literacy, family observations, hearing history, and the child’s opportunities to respond. Labels such as “Arabic speaker” or “bilingual” are too broad to interpret performance.
Sample communication across languages and contexts
Collect connected speech through conversation and narrative when possible, not single-word testing alone. Analyse the pattern of phonology, vocabulary, morphology, syntax, discourse, intelligibility, and pragmatic participation with appropriate linguistic knowledge. Collaboration with trained interpreters is a clinical process: brief before the session, clarify roles, preserve exact responses, and debrief afterward.
Use dynamic assessment to ask a different question
Test–teach–retest procedures examine modifiability, learning strategies, and response to mediated support. Dynamic assessment is not bias-free by definition, and its procedures and interpretation still require competence. It can add information when static standardized measures do not adequately represent the learner.
Translating a standardized test does not preserve its norms, psychometric properties, or cultural validity. Report scores only when their interpretation is defensible.
Form a converging-evidence judgement
Compare patterns across languages rather than looking for identical surface errors. Integrate history, observation, language samples, caregiver and teacher report, hearing status, dynamic response, and appropriately selected measures. Document limitations and uncertainty. Intervention planning should support functional communication and consider all languages important to the child’s relationships and participation.
