Purpose: This study used a semistructured open interview approach to gather information from school-based speech-language pathologists (SLPs) regarding their assessment practices for bilingual children with suspected language disorders. Method: Phone interviews were conducted with 25 school-based SLPs across the United States. The interviews explored assessment topics related to tool selection and rationale and the integration of assessment data to determine diagnosis and treatment eligibility. Results: The results of this study suggest that SLPs use a combination of norm-referenced and informal assessments when evaluating bilingual children. Informal measures, such as parent/teacher interviews and language sampling, were relied upon for diagnostic decisions, contrasting with the emphasis on norm-referenced testing observed in previous research. District policies and guidelines influenced norm-referenced assessments. Informal tools were used to capture natural language use, provide a comprehensive view of bilingual abilities, and gather detailed case histories. Conclusions: School-based SLPs integrate norm-referenced and informal measures in their bilingual assessment practices, with a notable reliance on informal assessments for diagnostic decision making. This approach contrasts with the reliance on norm-referenced measures typically observed in monolingual assessment practices, reflecting SLPs' potential recognition of limitations and biases in norm-referenced tests when used with bilingual children. The findings suggest that SLPs are aware of and use culturally sensitive diagnostic practices.
