Do SAT scores expire?
Many states do put the SAT scores on the transcripts for their students, but that is a highly controversial issue and they are not considered office score reports. This page on the College Board site explains reporting archived scores, but this won’t explain whether the institution you’re reporting to is interested in your scores from 1997, 1987, or 1977. Only they can answer that and, as 45moore45 said, they may have you take placement tests. The other tests available to you are the CLEP tests. If you’ve taken any college-level courses or had any work experience that can help you in the intervening years, you may be able to “CLEP out” of some of your intro-level courses for the cost of the test. Good luck!
