If illness prevents you from attending your IELTS test on the scheduled date, you can generally reschedule rather than lose your booking entirely.
- Contact the IELTS test agency/center as soon as possible — before or as close as possible to the test date — to explain that you're unable to attend due to illness.
- Provide proof of your illness, such as a medical certificate from a doctor, since the agency will typically require this before approving a reschedule.
- Expect an additional cost. Rescheduling isn't usually free — be prepared to pay an extra fee alongside your original test fee.
- Confirm your new test date in writing once approved, and keep the correspondence in case you need to explain any resulting delay to IRCC or another authority later.
