Certified Phlebotomy Technician (NHA) Exam

Who can take the CPT exam

NHA's candidate handbook (June 2026 edition) sets two eligibility pathways. Both start with a high school diploma or GED, or one you are scheduled to earn within the next 12 months.

Under either pathway you must also show evidence of 30 successful venipunctures and 10 capillary or finger sticks on live individuals before you sit. Students in a partnered program can test before graduation and hold a provisional certification: it expires 12 months after the exam date, cannot be renewed or reinstated, and has to be converted to a full certification once the diploma is in hand.

What is on the exam

NHA's test plan, built from a job analysis completed in 2024, splits the 100 scored items across five domains. The 20 pretest items are mixed in and look identical, but do not count.

The plan also lists core knowledge that can appear in any domain: blood components and blood groups, cardiovascular and vascular anatomy, hemostasis, pre-analytical errors, medical terminology, HIPAA and the Patient Bill of Rights, communication across cultures and abilities, and documentation.

What changed on January 7, 2026

NHA launched an updated CPT exam on January 7, 2026, following a practice analysis. NHA describes the change as having minimal impact on the domains and content areas, with an updated test plan and no pilot scoring period. The matching study materials, Study Guide 3.0 and its practice tests, were released on October 8, 2025, and NHA says anyone testing on or after January 7, 2026 needs that edition; the 2.1 guide and its practice tests were built for the retired form. The five domains and item counts above are the current plan.

What the CPT exam costs

NHA does not print the CPT exam fee on its certification pages or in the candidate handbook. The handbook says exam fees are shown in the Shop on nhanow.com, and you see the price in your NHA account when you register. Many training programs bundle the exam into tuition, so ask your program before paying on your own. What NHA does publish are the rules that decide whether you pay once or twice.

Exam format, where you take it, and what to bring

120 multiple-choice items in 120 minutes: 100 scored and 20 unscored pretest items you cannot tell apart, so pace for all 120, about a minute each. Where a summary on this page says 100 questions, it is counting the scored items only.

You can sit the exam at your school if it administers NHA exams, at a PSI testing center, or from home through live remote proctoring. For remote proctoring NHA requires an internet connection that supports VoIP and a computer that meets the proctoring system's requirements; NHA selects the proctoring provider when you register. At every venue you must show a current government-issued photo ID, such as a driver's licence or passport, that carries your photograph, signature and permanent address.

Scoring and your score report

Scores are scaled from 200 to 500 and 390 passes. NHA equates its exam forms so that 390 represents the same standard whichever form you draw, which is why there is no fixed number of questions you must answer correctly and why NHA reports no raw count. A 405 is a pass; a 385 is not. The score report in your NHA account shows the scaled score, pass or fail, and for each of the five domains whether you scored Above, Near or Below the passing standard. NHA warns that Near does not mean satisfactory, and that the domain categories cannot be added up to the overall result, because they are adjusted for the difficulty of the items you saw and the total is not.

When results arrive: a preliminary report immediately if you tested at your school, and within 48 hours if you tested at PSI or online; NHA posts certification results to your account within two days of scoring. Once you pass, NHA's public verification tool lists your name and credential, and it never shows scores or failed attempts.

If you do not pass

You may retake the exam after a 30-day wait. NHA's handbook allows three attempts, each separated by at least 30 days; a candidate who fails the third must wait one year before every further attempt. So the "three attempts" NHA states is the number you get at 30-day intervals, not a lifetime cap, and every attempt is paid at the full price. Use the Below domains on your score report to weight your review, then work the free practice test by domain and read the pass-rate article before judging a practice score.

NHA's CPT is one of five national phlebotomy certifications employers commonly accept, and in four states a state credential sits on top of it. The tables below put the CPT next to the others on the figures each body publishes, so you can see where NHA's 30-venipuncture rule, its two-year renewal and its at-home testing option stand. Figures are from each organisation's own pages and the state agencies' own rules, read on September 30, 2026.

NHA CPT against the other national phlebotomy certifications

Two things stand out. NHA's stick requirement is the lowest of the bodies that set one (AMT asks for 50 and 10; ASCP's classroom route asks for 100 unaided venipunctures), and NHA and AMCA are the only two that let you test from home. On renewal, AMT charges $75 a year and NCCT recertifies every year, while NHA's $195 every two years works out to $97.50 a year. ASCP's figures are as published on ascp.org on September 30, 2026; AMT's, NCCT's and AMCA's are quoted from their pages and handbooks linked under Sources.

States that license phlebotomists

Most states have no phlebotomy licence: the national certification is the credential. Four do, and each accepts the NHA CPT differently.

Related NHA credentials: the Certified EKG Technician (CET) uses the same 390 scaled standard and the same two-year, $195 renewal; the state-run CNA (NNAAP) exam is a different model, with a hands-on skills evaluation set by each state's nurse-aide registry rather than a scaled written score.

You can prepare for the CPT without paying for a course; paid prep earns its keep in a few specific situations, set out below. One number worth knowing when you compare: NHA's own Study Guide 3.0 package, the edition written for the exam form in use since January 7, 2026, comes with more than 600 practice questions across six timed attempts, two of them full 120-item mocks. That is the yardstick any third-party practice product should be measured against.

What NHA sells, and what is free

• Free from NHA: the CPT test plan (the five domains and their item counts) and the candidate handbook (eligibility, scheduling, scoring, retakes). The exam rules on this page come from those two documents.
• NHA Study Guide 3.0 and practice tests: the edition NHA says you need if you test on or after January 7, 2026. NHA lists more than 600 practice questions across six timed attempts, including a baseline test and a final test of 100 items plus 20 pretest items in two hours, the shape of the real exam. Prices are shown in NHA's store.
• Free here: a 150-question practice bank written to the current five-domain test plan, a study guide by domain, flashcards and a printable cheat sheet.

When paying makes sense, by NHA's own rules
