Accommodations for Applicants from China in Response to Coronavirus

We understand that as a result of the outbreak of novel coronavirus, all English tests for IELTS, TOEFL and the GRE and GMAT graduate entry exams in China are canceled at least through the end of February. All graduate program directors at Lehigh University are aware of the challenge posed by the outbreak and are willing to work with applicants who need extra flexibility.

In light of these extenuating circumstances, we are offering the following accommodations:

  •  Applicants affected by the cancellation of the IELTS and TOEFL exams may submit Duolingo English test results with DET score minimums required. To find your department’s DET score minimum, please refer to the published TOEFL/IELTS/DET score concordances:
  •  When these students arrive on campus, they must complete an additional English language assessment through Lehigh’s International Center for Academic and Professional English (ICAPE).
  •  Applicants to programs that require the GRE or GMAT who are unable to take the test before the application deadline may apply for conditional admissions, with the expectation that they will complete the required exam before arriving at Lehigh.

Applicants to Lehigh University’s graduate programs who are affected by the suspension of these exams in China should contact the directors of the specific graduate program to which they are applying to request accommodation.
