Things You Should Know

A graduate applicant should preferably have a Bachelor’s or Master’s degree in chemical engineering or chemistry. An applicant with records or scores that meet or exceed application guidelines listed above are not guaranteed admission.

The Iowa State chemical engineering graduate program encourages applications from qualified, non-traditional B.S. programs (such as chemistry, materials science, etc.). The department now offers a non-traditional Online Ph.D. Core program in the summer. It will be held June 11-August 3, 2018. For more information click here.

Admission of a qualified student also depends on a match between the student’s area of interest, research specialties of the faculty and availability of professors. Financial aid is usually considered only after an applicant is admitted to Iowa State University.
