Which assessment is designed to measure oral proficiency specifically?

The Bilingual Syntax Measure (BSM) I and II are specifically designed to assess oral proficiency, making them the correct choice for this question. These assessments focus on evaluating a learner’s ability to use language structures and syntax in their spoken output, which directly relates to oral proficiency. The BSM employs naturalistic tasks that require the test-taker to produce language in a way that reflects their everyday communicative capabilities, providing insights into their fluency and language control.

In contrast, the other assessments listed have different focuses or scopes. The Basic Inventory of Natural Language (BINL) assesses basic verbal skills and vocabulary but does not exclusively measure oral proficiency. The Language Assessment Scales (LAS), while they include oral components, also cover literacy skills and overall language proficiency instead of honing in solely on oral capabilities. The Woodcock Munoz Language Survey evaluates bilingual proficiency across multiple domains, including listening and reading, but again, it is not specifically tailored to measure oral proficiency alone.
