What IELTS score do you need for the University of Hertfordshire?

Course pages state each programme's requirement. Hertfordshire's list of higher requirements, with minimum band scores also applying:

Hertfordshire accepts Indian Standard XII English: 65% for undergraduates and 70% to 75% for postgraduates on the main page. Its India page gives 65% for undergraduate and 70% for postgraduate taught entry. That page also lists postgraduate IELTS as 6.0 or 6.5 depending on the course, with no band below 5.5. Rules for Pakistani and Nigerian school qualifications are not stated on the pages read.

IELTS, PTE and TOEFL results are valid for two years and must still be valid on the date your CAS is issued. Some courses accept only IELTS, and your offer will say so. One Skill Retake, IELTS Online and PTE Academic Online are not stated by Hertfordshire.

To join a pre-sessional English course you need an offer for a Hertfordshire degree and a UKVI Secure English Language Test (SELT), Academic IELTS, or a Trinity College test taken in the UK. Hertfordshire International College runs pathway courses.

For a Student visa, UK Visas and Immigration asks for English at CEFR B2 for degree-level study and B1 below degree level, per gov.uk. At degree level, gov.uk adds, your university can assess your English itself and may ask you to take a different test.

Requirements vary by programme and change between admissions cycles. The score that binds you is the one on your Hertfordshire programme page and in your offer letter, so check it there before you book a test.
