For a second-grade ELL with a suspected language impairment, which assessment component captures the student’s diverse language background?

The correct choice focuses on the use of parent interviews and dynamic assessment to capture the diverse language background of a second-grade English Language Learner (ELL) with a suspected language impairment.

Parent interviews are crucial as they provide insight into the child's linguistic capabilities, cultural context, and home language environment, which contributes significantly to understanding the student's language background. Parents can offer valuable information about the child's language development in their native language and any factors that might influence language learning, such as exposure to different languages at home.

Dynamic assessment is particularly important for ELLs, as it evaluates not just what the student knows at one point in time, but their potential for learning and how they can be supported in developing their language skills. This assessment style emphasizes a student's learning processes and can indicate how well a child might respond to interventions.

By combining both parent insights and dynamic assessment, educators can acquire a comprehensive view of the child's language abilities and needs, particularly in the context of their unique linguistic and cultural background, which is critical for effective intervention planning.
