While SAT scores maintain their validity indefinitely, the College Board advises that official SAT scores sent to colleges after a period of five years or more will be accompanied by a message indicating that the test score may be a less reliable indicator of the candidate's academic performance. Since the SAT underwent structural changes in 2016, numerous colleges no longer consider SAT scores from the previous format. Technically, SAT scores have no date of expiration, which means they are valid forever. It is crucial to note, however, that many universities refuse to accept results older than five years.
