IELTS One Skill Retake (OSR) lets eligible candidates retest one skill; the new band replaces that skill on your Test Report Form while other skills stay from the original test. Overall band is recalculated from the four skills. OSR does not average attempts, it swaps one score. Retakers should target the skill that blocks their goal (often Writing or Speaking) with criterion practice, not a full four-skill cram.
Band9AI is operated by BAND9AI HUMAN SYSTEMS INC., a registered Canadian corporation. Trust & verification

How OSR combines with your original TRF
See best AI tool for Band 8 retakes.
What to practice before OSR
| Retake skill | Focus |
|---|---|
| Writing | One criterion leak, often TA overview or TR |
| Speaking | Part 3 precision, not new vocabulary lists |
| Listening/Reading | Trap types and timing, not passive exposure |
When OSR beats a full retest
OSR saves time and fee when one skill sits 0.5 below target and others are secure. If two or more skills lag, a full test may be cheaper mentally and financially.
OSR timing
Eligibility window
Book OSR within the allowed period after your original CDI sitting, centre rules apply.
One skill only
Prepare as a single-skill sprint; do not dilute with full four-skill cram the week before.
Key takeaways
- OSR swaps one skill score, other skills stay from the original test.
- Overall band recalculates; there is no averaging of full tests.
- Target the single blocking skill with criterion feedback.
- Confirm eligibility and window on your centre booking page.
