Yes—you can take the ACT after high school graduation. Graduates, gap- year students, transfers, and adults register through the same MyACT process as current high schoolers. ACT stores your scores in your account; whether an older score still works for admissions is up to each college or program, not a single universal expiration date.
Who this guide is for
- Students who graduated and need a score for a later application
- Gap-year applicants updating an old result
- Transfer or returning adults asked for a standardized test
- Anyone whose high school score is too old for a program's stated preference
Do ACT scores expire?
Your scores do not vanish from ACT's records after graduation. You can usually still log into MyACT, view past reports, and send them. The catch is college policy: some schools accept scores from several years ago; others prefer or require a more recent test so the number reflects current skills. There is no single “scores last X years” rule that covers every campus—read each school's language and call admissions if it is unclear.
How registration works after high school
Create or sign into MyACT, pick a date and test center, upload a photo, and pay—same flow as how to register for the ACT. Expect questions about high school and graduation year; answer honestly. If you were homeschooled, see registering as a homeschooled student for the high school code and ID notes that still apply.
Fee waivers are typically aimed at currently enrolled 11th and 12th graders who meet financial criteria. After graduation you may need to pay the standard fee; confirm current eligibility on act.org before assuming a waiver will apply.
Should you retake as an older tester?
Retake if programs want a fresher score, your old Composite sits below their middle-50% or scholarship cutoffs, and you can put in focused prep. Keep an old score if schools accept it and it already clears your targets. Use the same decision frame as should you retake the ACT, and the attempt count guidance in how many times you should take the ACT.
Prep without a high school schedule
You will not have a counselor pushing calendar blocks, so treat prep like a short project: diagnostic, weak-area drills, full timed practice, review. How to study for the ACT and how long to study for the ACT still apply. If you have multiple dates on file and your colleges superscore, superscore retake strategy helps you aim the work.
The bottom line
Graduation does not lock you out of the ACT. Register through MyACT, verify each school's rules for older scores, and only retest when the gap and your practice evidence justify another sitting.
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.
