Formative Assessment vs. Summative Assessment: What's the Difference and Why It Matters

Formative assessment is day-to-day checking used to guide instruction. Summative assessment measures what students know at a point in time. Both are essential, but formative assessment is the engine that prevents surprises on summative moments.

Examples

Why formative assessment matters

Frequent, low-stakes checks let teachers adjust pacing, reteach concepts, and personalize support. They make learning visible and reduce anxiety about big tests.

Practical formative strategies

Designing summative assessments

Align your summative tasks with standards and the formative work students have practiced. Include rubrics and exemplars so expectations are clear.

Takeaway

Think of formative assessment as coaching and summative as the match. Coach well and students perform better when it matters.
