Correct Response: D. Developing-level English language learners have some technical language related to content areas but may still struggle with oral and written communication. In addition, research indicates that students perform best when a task is "just right" for them, meaning that the task is not too easy or too difficult. As a result, the teacher's primary consideration should be the level of difficulty of the questions. A, B, and C are incorrect because, when selecting an assessment for a specific purpose, administration-related features, such as how results are scored and reported (A), and surface- level features, such as the test's visual layout and attractiveness (B) or the number of speakers used in the aural input (C), are not as relevant as the content of the assessment.
