Which of the following best identifies the type of assessment used by Ms. McGuire?

Performance assessments require students to demonstrate their knowledge and skills through tasks or projects, typically assessing their ability to apply what they have learned. In this case, since Ms. McGuire is likely assessing prior knowledge rather than evaluating performance, this choice does not accurately reflect her assessment type.

Summative assessments evaluate student learning at the end of an instructional unit by comparing it against some standard or benchmark. These assessments are typically high-stakes and provide a summary of what students have learned, which differs from the purpose of identifying students' prior knowledge that a diagnostic assessment serves.

Selected response assessments involve questions that require students to choose an answer from provided options, such as multiple-choice questions. While this format can be part of diagnostic assessments, it does not fully capture the purpose of the assessment used by Ms. McGuire, which is to diagnose rather than merely select responses.
