Interpreting GRE Scores
Score Scale
- Verbal and Quantitative Reasoning: Scores range from 130 to 170 in one-point increments.
- Analytical Writing: Scores range from 0 to 6 in half-point increments.
Percentiles
Percentile ranks indicate how a test-taker’s score compares to others. For example, a percentile rank of 90 means the test-taker scored better than 90% of those who took the test.
GRE and Graduate School Admissions
Role in Admissions
While GRE scores are an important factor, they are considered alongside other application materials such as undergraduate GPA, letters of recommendation, personal statements, and relevant work or research experience.
Waivers and Alternatives
Some programs offer GRE waivers based on criteria such as professional experience, prior degrees, or GPA. Additionally, certain programs may accept alternative standardized tests like the GMAT for business school applicants.
Special Considerations
Accommodations
ETS provides accommodations for test-takers with disabilities, such as extended time, additional breaks, and screen magnification. Requests for accommodations must be made well in advance of the test date.
International Test-Takers
The GRE is available worldwide, and ETS provides additional resources and support for international test-takers, including country-specific information on test centers and registration.
Preparing for Specific Sections
