Failed the NHA Phlebotomy Exam? The 30-Day Retake Rule, the Three-Attempt Limit and Your Score Report

Not passing the NHA CPT is common enough that NHA has a fixed process for it: in 2025, 22.56% of CPT attempts didn't pass, by NHA's own pass-rate report (Passy's subtraction from its 77.44% pass rate). You can be back in the exam in about a month, and your score report tells you where to spend that month.

NHA's retake rules for the CPT exam

NHA's Candidate Handbook, updated October 5, 2026, says that if you don't pass on the first attempt, "you will be allowed to retake the exam after a 30-day waiting period." It continues:

• Three attempts. "You are allowed three (3) attempts to successfully pass the exam, with a waiting period of a minimum of thirty (30) days between each examination attempt."
• Then a year. "For each repeated failure after the third attempt, you are required to wait one (1) year before attempting to take the exam again."
• Full price. "For each retake attempt, you must re-register and pay the full examination price."

PSI's candidate bulletin states the same rule in its own words: two chances to retake, at least 30 calendar days apart, and a one-year wait after those, repeated after each further failure.

For example, if your first attempt is on November 2, 2026, the date 30 calendar days later is December 2, 2026 (Passy's arithmetic). Your NHA account and PSI's scheduler show the dates actually open to you.

How to register for an NHA CPT retake

1. Log in to your existing NHA account as a returning candidate. Don't create a second profile; the handbook tells returning candidates to log in instead.
2. Apply for the CPT exam again and agree to the attestation, as you did the first time.
3. Pay the full exam fee within 2 hours of applying, unless a school or employer is paying. NHA shows the current fee at checkout in your NHA account.
4. Book a date at least 30 days after your last attempt, at your school or with PSI at a test center or online.
5. Check your accommodations. NHA approvals last one year (365 days) from the approval date and apply to later exams in that period. If PSI gave your last exam and will give the retake, NHA says to call PSI to confirm the accommodations are on the new appointment (NHA).

What your score report tells you before the retake

Your report rates each of the five domains as Above, Near or Below the passing standard (or N/A if the domain had five or fewer questions on your form). NHA's handbook says to spend "considerable study time" on the domains rated Below or Near, and adds that you "should not assume that areas where an Above was received can be excluded," because "Above" can sit anywhere in its range. It also warns that a retake form spreads difficult questions differently, so ratings can shift even if your knowledge doesn't. The NHA CPT passing score guide explains each rating.

Because the ratings come by domain, your review should too, and planned NHA CPT practice is organized by domain, so you can start with the ones your report marks Below.

A 30-day NHA CPT retake plan

Passy's suggested split for the month between attempts, at about 7 hours a week:

The free NHA phlebotomy retake planner builds the same weeks from your own ratings and date.

Two habits help more than extra hours. First, keep a list of every practice question you miss and the rule behind it, and reread it before each session. Second, don't retake on the 31st day just because you can: if your timed practice still shows a weak domain, a week or two more costs less than another full exam fee. Thirty days is short for a full review, and a 30-day NHA Phlebotomy access period is planned for exactly that kind of focused month; checkout isn't open yet.

Retakes around an NHA exam update

When NHA launches a new version of an exam, everyone who tests on or after the launch date takes the new version, retakers included. Asked whether there is a grace period for candidates who fail just before a launch and whose 30-day wait ends after it, NHA's help center answers that they "will test on the new exam" (NHA). That happened with the January 7, 2026 CPT update, when NHA said anyone who tested and failed in the 30 days before the launch would retest on the new exam (NHA). As of October 28, 2026, NHA hadn't announced another CPT update.

Other routes back to the NHA CPT exam

Failing isn't the only reason NHA sends you back to the exam, and a retake isn't the only option after a fail:

• If you think the score is wrong, you can request hand rescoring in writing within 60 days of the exam (NHA may charge a fee) or appeal on NHA's form within 30 days. Both decisions are final.
• On the pre-externship or employer training route, NHA voids a passing score if the externship or on-the-job training isn't confirmed in time (90 or 180 days), and you have to retake the exam.
• A provisional certification that lapses before you convert it means retaking the exam.
• A certification expired for more than a year can't be reinstated; you take the exam again at the full price.
