Is GRE Compulsory for PhD in the USA?

The requirement for the GRE for PhD in the USA varies significantly by university, department, and field of study. Historically, the GRE for PhD in the USA was a standard admission component. However, in recent years, many programs have eliminated it entirely.

As of 2025, a growing number of PhD programs—especially in humanities, social sciences, and some STEM fields—have adopted GRE-optional or GRE-waived policies. Top institutions like MIT, Stanford, and UC Berkeley no longer require the GRE for PhD in the USA in disciplines such as biology, computer science, and sociology. This shift reflects a broader effort to promote equity and holistic admissions.

That said, not all programs have dropped the requirement. Some engineering, economics, and physical science departments still mandate or strongly recommend submitting a GRE for PhD, particularly if your academic record lacks rigor or research experience. In such cases, a strong GRE score can bolster your application.

How to Confirm Your Program’s Policy

To determine whether the GRE for PhD in the USA is compulsory for your target program, consult the official graduate admissions webpage of each department. Look for phrases like “GRE not required,” “GRE optional,” or “GRE recommended.” Avoid relying on third-party websites or outdated forums.

If the policy is unclear, contact the program coordinator directly. Some schools may waive the GRE for PhD for applicants with relevant master’s degrees, publications, or professional experience.

Crucially, international students should note that the GRE for PhD is unrelated to English proficiency. Even if the GRE is waived, you may still need IELTS or TOEFL.

The GRE for PhD in the USA is not universally compulsory. Many programs have removed it, but others retain it as a useful benchmark. Always verify current requirements for each specific PhD program before deciding whether to take the exam.
