Admission to the graduate program in environmental engineering is open to qualified students with a baccalaureate degree in engineering or science. A minimum baccalaureate grade-point average of 3.0 usually is required. Applicants from undergraduate programs other than environmental, civil, and chemical engineering may be required to take additional courses.

The GRE General section is required if one or more of the following conditions is true:

The undergraduate degree was not in environmental, civil, or chemical engineering.
An unaccredited college or university awarded the undergraduate degree.
The student's undergraduate cumulative grade-point average is below 2.75.
The year of the baccalaureate degree precedes the date of application to the College of Graduate Studies by more than six years, however, in this case, the examination requirement may be waived, with program approval, if the applicant's undergraduate grade-point average is 3.0 or above.
If the GRE is required, the admission decision is based on the applicant's performance on the quantitative section of the GRE along with the undergraduate grade-point average. A minimum of the 50th percentile on the GRE quantitative is required, but this minimum score does not guarantee admission.
