IELTS | Institutions – IELTS band scores 雅思考試概覽：
There is no pass or fail in IELTS. Candidates are graded on their performance, using scores from 1 to 9 for each part of the test – Listening, Reading, Writing and Speaking. The results from the four parts then produce an Overall Band Score.
This unique 9-band system measures scores in a consistent manner – wherever and whenever the test is taken. It is internationally recognised and understood, giving you a reliable international currency. IELTS scores have a recommended validity period of two years.
