The IELTS certificate, or test report form, is valid **for two years** from the date of the test. This validity period reflects the fact that English language proficiency can change over time, and many institutions and organizations prefer to have recent evidence of a candidate’s language skills. If you need to provide proof of your English proficiency for a specific purpose, such as university admission or visa applications, ensure that your IELTS test report is within this two-year validity period.
