Definition
Formative assessment is the ongoing measurement of learning during the learning process, used to adjust instruction rather than to certify outcomes.
Why it matters
Without formative signals, both learners and teachers keep doing what is not working; with them, the next session can target the right gap.
Scientific basis
Education research consistently finds that formative assessment is one of the highest-leverage instructional practices available.
How to apply it
- End every study block with a one-question self-check on the most important idea.
- Build review sessions around the questions you missed, not the ones you got right.
- Use periodic mock exams whose only purpose is to inform the next phase of study.
Common mistakes
- Treating mock exams as a final rehearsal rather than as a diagnostic.
- Skipping analysis of why an answer was wrong.
- Designing assessment that tests recognition rather than retrieval.
Examples
- A piano teacher listening to a student's piece and assigning the next week's work based on which passages broke down.
- A coding mentor reviewing PR comments to identify recurring weakness categories.
