Formative assessment is assessment carried out during the teaching and learning process, with the primary purpose of improving learning rather than measuring it. It answers the question: Where are learners now, and what do they need next?
Often called "assessment FOR learning" (Black & Wiliam 1998), in contrast to Summative Assessment ("assessment OF learning").
| Technique | What it reveals |
|---|---|
| Monitoring during tasks | Real-time production, common errors, engagement levels |
| Questioning (targeted, open) | Depth of understanding, misconceptions |
| Exit tickets | What was learned (or not) in a specific lesson |
| Mini whiteboards / quick polls | Whole-class understanding at a glance |
| Peer assessment | Learners internalise criteria; reveals their understanding of quality |
| Self-assessment | Metacognitive awareness; surfaces perceived vs actual ability gaps |
| Error analysis | Systematic patterns in learner output that indicate developmental stage |
| Observation checklists | Structured tracking of specific skills during communicative activities |
Black & Wiliam's (1998) meta-analysis found that formative assessment produces significant learning gains, among the largest effect sizes of any educational intervention. The mechanism is straightforward: it closes the gap between where learners are and where they need to be by making that gap visible to both teacher and learner.
In language teaching specifically:
The same instrument can serve both purposes depending on how it is used. A writing task graded and filed is summative. The same task analysed for error patterns, discussed with the learner, and used to plan the next lesson is formative. The distinction is in the purpose and use of the information, not the format of the assessment.
