Iowa State University has a two-step application process. The first step is free and will generally be reviewed within two weeks. That outcome will determine if you are invited to apply for the second step. Students that are encouraged to submit a full application as part of the second step can update their profile. Transcripts, English proficiency scores (for international students), and letter of recommendations are required for step two.

Fill out graduate college application.

A graduate applicant should preferably have a Bachelor’s in chemical engineering or chemistry. However, the Iowa State chemical engineering graduate program also encourages applications from qualified students with non-traditional B.S. degrees (such as materials science, biochemistry, etc.) The department offers an online preparatory summer program for non-traditional Ph.D.-seeking students. It is offered online in the summer. For more information click here.

  • Fall admission applications will be reviewed beginning December 1, with full consideration of all applications received through January 15.

A graduate applicant should preferably have a Bachelor’s degree in chemical engineering or chemistry. In addition to satisfying the normal graduate degree requirements, students without an undergraduate degree in chemical engineering must demonstrate proficiency in the major undergraduate subjects of chemical engineering: material and energy balances, heat and mass transfer, fluid mechanics, thermodynamics, and chemical reaction engineering. This is usually accomplished by completion of an online preparatory summer program. The Director of Graduate Education will determine if additional undergraduate courses are needed based on the student’s performance in the summer program.
