Band Descriptor Self-Assessment
writingspeakingaccuracyreviewindividualmedium prep20-30 min
Students read the exam band descriptors carefully, then rate their own performance against each criterion. Forces learners to understand how they are scored, not just what score they got.
Procedure
- Distribute the band descriptors (IELTS public descriptors, Cambridge writing rubrics, TOEFL rubric — whatever applies).
- Students read descriptors for 2 adjacent bands (e.g., Band 6 vs Band 7).
- Identify distinctions (10 min): pairs answer
- What does a Band 7 writer do that a Band 6 writer does not?
- Can you give an example of each?
- Self-rate own work: students read their own recent essay; rate themselves on each criterion, giving evidence from the text.
- Targeted revision: pick the lowest-scoring criterion. Revise the essay attending only to that criterion.
- Rerate after revision. Did the move work?
Why It Works
- Demystifies scoring: learners who haven't read descriptors are hitting a target blindfolded.
- Actionable targets: "improve cohesion" becomes "use three different reference-link devices, not just 'this'".
- Calibration: students who rate themselves too high or too low can be corrected with evidence.
Good Descriptor-Pair Comparisons
| Exam | Contrast |
|---|---|
| IELTS Writing | Band 6 vs Band 7 — cohesion + lexical resource differences |
| IELTS Speaking | Band 6 vs Band 7 — fluency and coherence differences |
| CAE Writing | Mark 4 vs Mark 5 — communicative achievement |
| TOEFL Writing | Score 3 vs Score 4 — organisation and development |
Variations
- Peer self-assessment: one student self-rates, partner rates independently. Compare.
- Before-and-after: rate at the start of a course and again at the end. Progress visible.
- Descriptor rewriting: students rewrite the official descriptor in plain language. Deepens understanding.
Tips
- Official descriptors often use vague words (appropriate, generally accurate). Spend time unpacking these with examples.
- Overly generous self-raters need calibration: show them a teacher-rated sample that matches their claimed level.
- Best done across multiple essays over time; one-shot self-rating is just a snapshot.
