What IELTS score do you need for Texas Lutheran University?

The page says any student, whatever their nationality, who completes secondary education or earns a tertiary degree from an accredited institution in Australia, Canada (excluding Quebec), Ireland, New Zealand, South Africa, the Bahamas or the United Kingdom is exempt from submitting English proficiency scores.

Undergraduates whose native language is English may send SAT or ACT results instead: 500 on the SAT Evidence-Based Reading and Writing section, or 21 on the ACT English and Reading sections. Graduate and doctoral students graduating from a regionally accredited institution within the United States do not need to submit proof of English proficiency.

The undergraduate checklists also ask for a Confidential Report of Proficiency in English form, and say scores must be sent directly from the testing service. The page lists TOEFL and IELTS only, not PTE Academic or Duolingo.

The page also notes that international students on face-to-face programmes need a non-immigrant visa, and that online programmes do not give one.

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