Environmental Science is a highly competitive, direct-admit graduate program, where students are admitted into the lab of a major professor as well as into the ENVSC program. As such, it is imperative that prospective students identify a potential professor before applying to the program. Applicants should review our faculty directory to identify research faculty working in areas that align with their interests and goals. Once relevant faculty members have been identified, applicants should contact those faculty directly to inquire about open graduate positions and funding opportunities for their planned term of entry. Only applicants that contact faculty, apply for the program and are then  nominated by a faculty member will be considered for admission to the program.

The ENVSC program does not provide conditional admission. We also do not provide application fee waivers.

All applicants should have a degree in one of the biological, physical, or engineering sciences from an accredited institution. 

We no longer require the GRE for admission to our program.

MS applicants must meet the following requirements:

• An undergraduate GPA of 3.0 or better
• Research readiness
• International applicants: An English proficiency score of 79-iBT, 550-PBT, 6.5-IELTS, 53-PTE or 105 Duolingo (NOTE: this score will only be good for Summer - Fall 2025). Beginning Spring 2026, the minimum Duolingo score will be 115. You are exempted from providing an English proficiency score if you hold a bachelor's or higher degree from a country where English is the ONLY official language. Please refer to the attached document for a listing: Countries where English is the only official language.

PhD applicants must meet three of the following requirements:

• An undergraduate GPA of 3.0 or better
• A graduate GPA of 3.3 or better
• Research readiness
• International applicants: An English proficiency score of 79-iBT, 550-PBT, 6.5-IELTS, 53-PTE or 105 Duolingo. The Duolingo score will only be accepted through spring 2025 semester.

The Admissions Committee begins reviewing nominated applicants in February. Initial admission offers are made in March. Applicants nominated after February are reviewed on an individual basis. Applicants that do not receive a nomination are notified in April.
