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.

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.

Replaced skill New band from OSR sitting
Unchanged skills Original L/R/W/S scores kept
Overall Recalculated mean of four skills

What to practice before OSR

Retake skillFocus
WritingOne criterion leak, often TA overview or TR
SpeakingPart 3 precision, not new vocabulary lists
Listening/ReadingTrap 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.

FAQ

: only the retaken skill is updated; other skills stay from the original sitting if OSR rules are met.
and available skills depend on test centre policy, confirm on your booking page for Academic or GT CDI.
: same three-part live Speaking with an examiner; only the delivery mode timing may follow your CDI centre rules.
