* The program you're applying to: Different programs may have different requirements and may not accept credits from certain institutions or courses that are too old.
* The accrediting body: Accrediting agencies may have guidelines about the age of credits accepted for accreditation purposes.
* Changes in curriculum: Courses may be updated or discontinued, making older credits less relevant or not applicable.
Therefore, while there isn't a set expiration date, it's best to contact the admissions office or the specific academic department at Jacksonville State University to determine the acceptability of your credits before applying. The older the credits, the higher the chance they may not be accepted.
