Which assessment type measures student understanding during instruction to guide teaching?

The assessment type that measures student understanding during instruction to guide teaching is formative assessment. This type of assessment is designed to provide ongoing feedback during the learning process. It allows educators to identify areas where students may be struggling and adjust their teaching methods accordingly.

Formative assessments can take various forms, including quizzes, classroom discussions, observations, and informal checks for understanding. The primary goal is to enhance and inform the learning experience rather than simply evaluate students at the end of a learning period.

In contrast, diagnostic assessments are usually administered before instruction begins to assess prior knowledge and skills, while summative assessments occur at the end of a learning unit or course to evaluate what students have learned overall. Integrated assessments combine various forms of assessment into one assessment but do not focus primarily on guiding ongoing instruction during the learning process like formative assessments do.
