What is the primary purpose of formative assessment in an instructional unit?

• A. Monitor learning, guide instruction, and adjust teaching based on real-time evidence.
• B. Provide final grade at the end of instruction.
• C. Assess teacher performance only.
• D. Confirm curriculum alignment.

Answer: (A)

Formative assessment focuses on checking learners’ understanding while instruction is happening and using what you learn to shape the next steps. The primary purpose is to monitor how students are grasping the material in real time and to adjust teaching accordingly. This creates a quick feedback loop: you gather evidence through short checks, questions, or observations, interpret what it says about gaps or misconceptions, and adapt explanations, activities, or supports to move learning forward. By tailoring instruction to student needs as the unit unfolds, you help each student progress more effectively. This differs from final-grade testing at the end of instruction (summative assessment), which evaluates what students have learned overall, not how learning unfolds during the unit. It’s also not about evaluating teacher performance alone or merely confirming curriculum alignment; those are separate aims.
