Concept:Formative assessment is a continuous process during instruction. Its goal is to gather feedback, not to rank or label students.

It helps teachers find areas where students struggle and adjust teaching accordingly.
Common tools include projects, oral tests, assignments, portfolios, class tests, and anecdotal records.
Option A (comparison) and Option B (labelling) are not purposes of formative assessment.
Option D (weekly tests) is too limited; formative assessment uses varied methods, not just weekly tests.
Thus, the correct purpose is to use a variety of ways to collect information about student learning.
Answer:Option C: to use a variety of ways to collect information about the students learning.
