How long are IELTS, TOEFL, and PTE Academic certificates valid for?

IELTS, TOEFL, and PTE Academic certificates all carry a validity of two years from the test date. After that period, institutions usually ask for a fresh result. Cambridge English Qualifications such as B2 First, C1 Advanced, and C2 Proficiency are the exception, as they remain valid for life and never expire.

Which English certificate has lifetime validity instead of expiring after two years?

Cambridge English Qualifications hold lifetime validity. The popular exams in this family are B2 First (FCE), C1 Advanced (CAE), and C2 Proficiency (CPE). Unlike IELTS, TOEFL, PTE Academic, and the Duolingo English Test, which all expire after two years, a Cambridge certificate stays valid permanently and is respected by universities and employers worldwide.

Is the Duolingo English Test accepted for immigration purposes?

The Duolingo English Test is accepted by thousands of universities and is valued for being fast and affordable, with reading, writing, listening, and AI-powered speaking sections. However, it is not always accepted for immigration purposes. For visa applications, IELTS, TOEFL, and PTE Academic tend to be the safer choices depending on the destination country.

Which English exam is best for university admission and immigration?

For university admission, IELTS, TOEFL, and Cambridge qualifications are widely accepted, with the International English Test also gaining recognition. For immigration, IELTS, TOEFL, and PTE Academic are the usual requirements depending on the country. IELTS is accepted by more than 11,000 organisations worldwide, covering universities, governments, and employers.

How does the International English Test compare with IELTS and TOEFL on cost and speed?

Traditional exams like IELTS and TOEFL can be expensive, time-consuming, and stressful. The International English Test offers a more affordable and accessible alternative with instant results and downloadable certificates. It is CEFR-aligned across A1 to C2, covers grammar, vocabulary, reading, listening, writing, and speaking, and uses AI-powered evaluation for the speaking and writing sections.

How many institutions and organisations accept IELTS and TOEFL worldwide?

IELTS is accepted by more than 11,000 organisations around the world, including universities, governments, and employers. TOEFL is trusted by over 12,000 institutions across more than 150 countries, mainly for study abroad and academic purposes. Both tests follow a four-skill format covering reading, listening, writing, and speaking.

Can I choose how long my International English Test certificate stays valid?

Yes, the International English Test offers customizable validity, so you can select a certificate that lasts one year, two years, or for life. This flexibility sets it apart from fixed-validity exams, where IELTS, TOEFL, PTE Academic, and Duolingo all expire after two years while standard Cambridge qualifications remain valid permanently.
