The IELTS band descriptors are essential to understand, as they detail the criteria examiners use for grading, all of which are embedded in the IELTS exam syllabus. These descriptors cover task achievement, coherence and cohesion, lexical resource, and grammatical range for writing and speaking sections.

For speaking, fluency, pronunciation, and the ability to discuss complex ideas are key. For writing, clear argumentation, structure, and vocabulary are crucial. Familiarizing yourself with the IELTS exam syllabus can give you insight into what examiners are specifically looking for at different band levels.
