Admitted graduate students who are non-native English speakers also sit the English Placement Test at the start of the first semester unless exempt. Students who do not pass are placed in English courses that must be completed in the first year.
For comparison, the undergraduate page sets IELTS at 6.0 with all sub-scores 5.5 or above, and the Graduate College page sets IELTS at 6.5.

If your TOEFL score is below Iowa State's level
Neither page offers conditional admission for a low TOEFL score. Undergraduates can instead meet the requirement by completing the equivalent of Iowa State's English 1500 or 2500 with a B or higher at an accredited US college, or through the other exemptions listed. Graduate applicants with a degree from a country where English is the only official language are also covered.
Requirements vary by programme and change between admissions cycles. The score that binds you is the one on your Iowa State programme page and in your offer letter, so check it there before you book a test.
