IELTS One Skill Retake: How Scoring Works

OSR policy · Score combine · May 2026

Direct answer

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.

Use the matching skill hub to diagnose the blocking criterion, then retest that skill only. Related retake guides: why scores drop on a retake, post-exam retake strategy, 0.5-band short retake strategy, AI tools for retakers.

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.
