IELTS assessment criteria

IELTS assessment criteria

You can be confident that your IELTS score is a true reflection of your English language proficiency. Examiners use detailed assessment criteria when they mark your test.

The IELTS 9-band scoring system is used to measure and report scores in a consistent manner. Examiners are trained in line with globally agreed standards to ensure consistency in the quality of their assessment.

Listening and Reading tests

IELTS Listening and Reading tests both contain 40 items. Each correct item is awarded one mark.

Writing and Speaking tests

Examiners use detailed performance descriptors when assessing the Writing and Speaking tests. These band descriptors describe performance in four categories:

  • task achievement
  • coherence and cohesion
  • lexical resource
  • grammatical range and accuracy
