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.
