Generally one to two years. The important part is who decides: the window is set by the nursing program that reads the score, not by ATI. Two years is the most commonly published figure, one year is not unusual, and a program can be stricter than both.
That makes validity a question you have to answer per program rather than once. If you are applying to four schools, the shortest window on the list is the one your planning has to respect.
Measured from when, exactly
There are two different clocks in use and they can be months apart:
| The rule the program uses | What it means for you |
|---|---|
| Valid for n years from the test date | Count forward from the day you sat the exam |
| Valid for n years at the application deadline | The score must still be inside the window on the day applications close, not on the day you apply |
| Valid for n years at the start of the program | The rarest of the three, and the most generous |
Ask which one applies, in writing, and note it next to the deadline for each program. A two-year window from the test date and a two-year window measured at the deadline are not the same rule, and a score that satisfies one can fail the other.
Why this bites: deadlines run 9 to 12 months ahead of the start
Nursing application deadlines cluster 9 to 12 months before the intended start date. Most people plan around the month they want to begin classes, which is the wrong end of the calendar. The date that governs the exam is the deadline.
Work an example. You want to start in the fall. The deadline is roughly the previous fall or winter, call it 12 months before you would walk into class. Now ask how old your score may be at that deadline:
| Validity window | The earliest test date that still counts, relative to the deadline | Relative to the start date |
|---|---|---|
| One year | 12 months before the deadline | About 21 to 24 months before you start |
| Two years | 24 months before the deadline | About 33 to 36 months before you start |
The practical failure is being too early, not too late. Sitting the exam a long time before you apply feels organized, and under a one-year rule it can mean the score is dead at the deadline while the application is still open. Get the deadline first, then the validity rule, then pick the test date.
Leave room for a second attempt
The other reason not to book late is that a retake is not instant. ATI commonly requires a minimum of 14 days between attempts and allows around three a year, and your program can set a stricter limit on top of that. A retake also needs preparation between the sittings, and the result then has to reach the program before it closes applications.
So the first sitting wants to be far enough ahead of the deadline that a wait, a rebuild and a second sitting all still fit inside it. If the only date available is a few weeks before the deadline, you are buying one attempt with no fallback. How many attempts you get, and what to change between them.
If a score expires
There is no renewal and no extension. An expired score is retaken in full: all four sections, 170 questions, 209 minutes, at the usual $70 to $120 depending on whether you test at an institution or online through ATI. You cannot re-sit only the section that went badly, and there is no returning customer discount. Registering, cost and test day.
Two details that catch people out. Every completed and scored attempt normally counts against a program's attempt limit, whether or not you ever sent the result. And programs differ on which attempt they read: some take your highest, some your most recent, some want to see all of them. If your current score is still valid and you are retaking to improve it, find out which rule applies before you book, because a lower second score can cost you at a program that reads the most recent.
Plan the test date backward from the deadline
The sequence that avoids all of this is short:
- Find the application deadline for the cycle you are entering, for every program on your list.
- Find each program's validity rule and what it is measured from. Take the strictest.
- Subtract the time the official report needs to reach the program, which is not the same as the time it takes you to see your score.
- Pick a first test date early enough inside that window that one retake still fits.
- Count backward from the test date to decide how much preparation the plan can actually hold.
Step 5 is where most of the outcome is decided, and it is the only step you fully control. The study plans, from two weeks to eight.
Common questions
How long is a TEAS score good for?
Generally one to two years, with two years being the figure most commonly published. The program sets the window rather than ATI, so it varies, and some programs accept a score for only a year. Confirm it on the admissions page for the cycle you are applying to, because a rule that applied last year is not binding on this one.
Does the validity period start from my test date or my application deadline?
That varies by program, and the difference can be months. Some programs count a fixed number of years forward from the day you sat the exam, others require the score to still be within the window on the application deadline, and a few measure it at the start of the program. Ask the admissions office which applies and keep the answer in writing.
Can I use the same TEAS score for more than one program?
Usually yes, and most applicants do apply to several. Each program applies its own validity rule to the same score, so a result that is comfortably current at one school can be expired at another. Plan against the shortest window on your list, not the most generous one.
What happens if my TEAS score expires before the deadline?
You retake the whole exam. There is no renewal, no extension and no way to re-sit a single section, so an expired score means all four sections again at full price, $70 to $120 depending on where you test. Factor in the minimum wait between attempts and the time the official report needs to reach the program before you assume a late retake will land in time.
Can I retake the TEAS to refresh a score that is about to expire?
Yes, subject to the usual limits: commonly a minimum of 14 days between attempts and around three attempts a year, with programs free to be stricter. Before booking, check which attempt your program reads, because at a program that takes your most recent score a weaker second sitting replaces a good first one.
