The Admissions Committee recommends a TOEFL score of 90 or above on the internet-based test, 230 or above for the computer-based test or 570 or above for the paper-based test.
The International English Language Testing System (IELTS) is also acceptable. A score of 7 or higher is preferred.
Although we do not require students with an SAT I Verbal score of 570 or higher to submit TOEFL test results, we STRONGLY recommend that all students whose first language is not English to take this exam.

Academically strong students whose TOEFL scores are slightly below Lehigh's recommended scores may be considered for admission on a conditional basis. Conditional admission entails successful completion of the seven week intensive English as a Second Language program (StepUp).

SAT/ACT
SAT ranges of the middle 50% of admitted students were 620–710 for verbal and 660–740 for math. Though it's not required, the middle 50% of admitted students submitting ACT scores ranged from 28-32.

SAT成绩不是底线，是录取的人的平均分
