Computer-delivered IELTS Speaking is still a live three-part interview with a certified examiner, the scoring criteria do not change. What changes is logistics: you may take Speaking on the same day before or after L/R/W on screen, in a smaller room, sometimes with headset use. Examiners apply the same FC, LR, GRA, and P descriptors. Prepare for scheduling order and screen fatigue, not a different rubric.

What stays the same
What feels different on CDI
| Factor | CDI experience |
|---|---|
| Scheduling | Speaking may be same day as screen sections |
| Environment | Test-centre noise, smaller booths |
| Fatigue | Screen work before Speaking can dull fluency |
Prep adjustments
- Mock Speaking after 2+ hours screen work once weekly.
- Practice with slight background noise, not silent room only.
- Record Part 2+3; score with criterion AI.
Test-day order
Speaking after screen work
If Speaking follows L/R/W, warm up your voice during the break, do not go silent until Part 1.
No format change
Parts 1–3 structure is identical to paper IELTS.
Key takeaways: Computer-Delivered IELTS Speaking
- CDI Speaking is not AI-scored, it is live examiner marking.
- Rubric is identical; logistics and fatigue differ.
- Same-day screen sections can affect fluency, simulate that order.
- OSR Speaking follows the same format if you retake one skill.
