Graduate: IELTS 6.5, check your department
Your application will not be evaluated until NAU receives valid scores. NAU lists IELTS, Duolingo and TOEFL for most graduate programs, and tests must be taken within two years of the term in which you start. Some programs have higher requirements or section minimums, and not all departments accept every exam, so check your program in the academic catalog. See international graduate admission.
Proof of English may be waived if you hold a passport from an approved English-speaking country or completed a university degree in one. NAU's list includes the UK, Ireland, Australia, New Zealand, Canada, Kenya, Nigeria, the Philippines and Singapore, but not India. Applicants who fall short may be eligible for the Program in Intensive English (PIE).

Undergraduates can use TOEFL iBT or Home Edition 70 (MyBest scores accepted), IELTS 6.0, Duolingo 95, PTE 56, ACT English and Reading 21, SAT EBRW 350, or IB English. Graduates of English-taught high schools qualify with four years of English and a school letter confirming every course was taught in English, which can suit English-medium school leavers. If you fall short, you may take a placement test on arrival and enrol in PIE until you reach the required level. See application steps.
Student visa and next steps
The US F-1 student visa sets no English test score of its own. What counts is the requirement Northern Arizona University sets for admission, which leads to your Form I-20. For the wider picture of studying in the US with each test, see IELTS for the USA and PTE for the USA.
Requirements change between admission cycles. Check the NAU international graduate admission page again before you book a test, and check your own program page, which can set a higher bar. To see where you stand now, take a timed IELTS mock test.
