  • The Department of Chemistry is not actively seeking Master's Degree applicants at this time, and students who apply for the MS program will be declined. An exception is made for active service US military applicants who are fully funded by scholarships. Please consult with the Assistant Department Head for more information.
  • Current master's students wishing to move to a doctoral degree program in this same graduate program will not be required to submit a new application.
  • Students enrolled in programs outside of the United States must complete the equivalent of a United States Bachelors Degree prior to matriculation.
  • International students who are enrolled in a graduate-level degree-seeking program in the United States at the time they apply to Purdue, must complete that degree (Master's or Doctoral degree).

  • International students earning a BS or MS degree at a US University may request a waiver from the testing requirement, which may be granted based on TOEFL or IELTS scores older than two years. Waivers should be requested directly from the Department Assistant Head. For the purposes of priority review, your application will not be considered complete until either a score is recorded or a waiver has been granted.
