Graduate programs staff members answer e-mail messages and phone calls regarding your admission, but they do not determine admissions criteria and are not involved in admissions decisions. Admission into the program is determined by our Graduate Studies Committee (consisting of faculty), which reviews your completed application package. (For more information on the review process, please see “Have I been admitted?” below.)

Note: Individual faculty cannot comment on an applicant’s chances for admission, so we ask that you do not contact faculty directly regarding your admission status.

Graduate programs staff members answer e-mail messages and phone calls regarding financial assistance, but they do not determine financial aid criteria and are not involved in financial aid decisions. Your financial assistance opportunities cannot be determined before our Graduate Studies Committee reviews your completed application package and faculty reviews your complete application. (For more information on the review process, please see “Have I been admitted? below”)
Fall semester applications must be received by January 1, and spring semester applications must be received by August 15. We do NOT recommend that you wait until the deadline date to submit your online application as this may delay the process.
The application fee is required in order for us to process your application. Unfortunately, we cannot waive or defer the fee.

Note: If you are a U.S. citizen AND are a member of an underrepresented minority group, please contact the program assistant for graduate education Kristin Clemens, at, to ask about fee deferral options.

After March 1, if you wish, you may inquire with the admissions office regarding the status of your application at

Due to the high volume of applications received in the Office of Admissions and our Graduate Programs Office during December through February, you may not receive acknowledgement that we have received your applications or supporting materials.

However, if we do not receive the necessary academic records (and graduate examination scores, if required) within a reasonable time after your application is received, we will send you an e-mail notifying you that your application is incomplete and prompting action. If you receive this e-mail, you must complete this action to be considered for admission into our program.

There are no cut-off scores for the GRE examination, as the scores are evaluated within the context of your entire application package. Because admission is competitive, we have provided the recommended guidelines below based on our experience.

  • TOEFL score: Guideline is a minimum of 570 (paper-based) or 79 (iBT).
  • GRE score: Guideline is a minimum of 700 (quantitative) and 3.5 or 700 (analytical).
TOEFL scores are required of international students whose native language is not English. This university requirement cannot be waived.

Note: For the purpose of applying to Iowa State, English may be considered your native language if you have been raised in an environment where English is the only official language of your locality and nation and English is the language used in your home. If your native language is not English, you must submit scores from either the Test of English as a Foreign Language (TOEFL) or the International English Language Testing System (IELTS).

This requirement is waived if you have earned a bachelor’s or master’s degree from a country where English is the only official language.

The university requires official results be sent directly by the Educational Testing Service. You can find out more information about and register for the GRE at Our school code is 6306.

Note: All official GRE and TOEFL scores come to the Office of Admissions, so you do not need a department code.

We highly recommend you arrange to have your scores sent before the application deadline. However, it is acceptable for your GRE and TOEFL score reports to arrive after the application deadline as long as it is during the review process, which is one to two weeks after the application deadline. If your reports arrive within the above timeframe after the deadline, your chances of being admitted or receiving financial assistance will not be affected unless final admission decisions have all been made. You can send an inquiry to the Office of Admissions regarding the status of your application.

Note: The Office of Admissions uses only official scores to process your application. Copies of scores will not be considered.

In most cases, this means that we have not yet received your official GRE and/or TOEFL score report from ETS. If you have already requested ETS to send your official scores, you need not take any further action.

Note: The Office of Admissions uses only the official scores to process your application. To expedite your application’s processing, we request that you send photocopies of your official GRE and TOEFL results.

On the application, you are asked to indicate your GPA at each institution attended. You should provide the GPA attained and the maximum grade attainable in the grading system used at your institution.

For example, most U.S. schools have a 4-pt. grading system where A = 4, B = 3, C = 2, D = 1, F = 0. If your GPA score on that scale was 3.00, you would list it as 3.00/4.00. Other examples of GPAs on grading scales used in other countries are 80/100; 8/10; 2nd Division, Upper/1st Division; etc.

A simple conversion to the 4.0 scale would be useful for application processing—it does not have to be exact; an estimate is acceptable. Note that while the department committee will use this estimate to review applicants, the Admissions Office will evaluate your grades based on the information on your official transcript.

Once your application package is complete, the contents are cataloged and forwarded to our Graduate Education Committee. All applications are held for review until after the application deadline—there are no early decisions. Please contact if you have an extenuating circumstance that requires an early decision.

The application packages of applicants who are deemed qualified for admission by the committee will be forwarded to the faculty for admission and assistantship consideration. Offer letters will be sent electronically around the first two weeks of March for fall semester applications and around the first two weeks of October for spring semester applications.

Your completed application may be reconsidered for the next concurrent semester after your original application semester (for example, if you applied in fall, you can be reconsidered in spring). You will be sent an e-mail asking if you would like to be reconsidered. You may also send additional information at this time. For example, additional transcripts from other schools you may attend prior to admissions.

Note: Your application is valid only for one year.

If you are already committed to a research-oriented career (industry or academia) then you should considering applying directly to the PhD program. For the purposes of flexibility you can let faculty know in your Statement of Purpose that you would be willing to be considered for admission to the master’s program.
