ETS’ official response to how long GRE results are valid is that both general and topic test GRE scores are valid for five years from the test date. As a result, if you took the test on April 10th, 2020, your results will be valid until April 9th, 2025. If you’re ever unsure about the validity of your GRE scores, use the official test date calculation, which can be located at the bottom of ETS’s Getting Your Scores website.
