A gap year does not erase a valid ACT sitting. Many colleges still want a score from the last three to five years. Retest only if the number is old for that campus or below the new list.
Keep the score if
It still falls in the college's window and at or above the 50th you care about. Sending: send scores to colleges.
Sit again if
The sitting is outside that college's years, you never tested, or the new list is a band higher. After high school: taking the ACT after high school. Whether another date is worth it: should you retake.
The bottom line
Confirm each college's age rule. Do not retest for sport, and do not assume a junior-year 28 lives forever.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
