The correct answer is To monitor student progress and adjust instruction because formative assessment serves as a real-time diagnostic tool to guide the teaching and learning loop.
Ongoing Feedback: Formative assessment operates as 'assessment for learning,' gathering immediate data on student comprehension to identify misconceptions and learning gaps as they happen.
Instructional Adaptability: The data collected allows teachers to adjust their pacing, try alternative teaching strategies, or implement targeted interventions before moving to high-stakes testing.
Incorrect Options:
To assign final grades is incorrect because evaluating cumulative mastery for final marking is the job of summative assessment at the end of an instructional unit.
To punish low-performing students is incorrect because educational assessments are designed to support student growth and isolate comprehension needs, not to enforce punitive disciplinary actions.
To compare students is incorrect because comparing individuals against peers represents norm-referenced testing rather than a progress-monitoring diagnostic loop.
