The NHA phlebotomy exam leads to the Certified Phlebotomy Technician credential (CPT). Since January 7, 2026 it follows a new test plan: 120 questions, of which 100 are scored and the rest are pretest items, in 2 hours, at a test center or with live remote proctoring. To sit it, a candidate needs a high school diploma or equivalent and either a phlebotomy training program or supervised work experience, and must document 30 successful venipunctures and 10 capillary sticks performed on live people. The score is scaled: scaled score of 390 (scale 200 to 500). After a failed attempt the candidate waits 30 days; after 3 attempts the wait becomes a year. The credential is renewed every 2 years with 10 continuing education credits. The mock above keeps the full length and time, mixes the five domains in their test plan weights and marks your share of right answers against a study target of 80% chosen by this site.

How the mock is built
The mock draws 120 questions, the full length of the real form, because the pretest questions are mixed in and you cannot tell them apart. Each domain gets its share of the test plan: safety, compliance 31, patient preparation 24, routine collections 34, special collections 14, processing 17. You have 2 hours; the clock runs in your browser only. The question map shows answered and flagged questions, and you can move freely before marking the test. Corrections and explanations appear at the end, with your score by domain.
The mark is your share of right answers, set against a study target of 80%. That target is ours, not the NHA's: the official standard is a scaled score, scaled score of 390 (scale 200 to 500), which cannot be rebuilt from a count. A mock above the target in several attempts, on different draws, is a better sign than one high score.
Eligibility in practice
The NHA candidate handbook (archived copy of October 9, 2026, cited in the sources) sets two routes after a high school diploma or equivalent:
- Training: completion of a phlebotomy training program within the last five years;
- Experience: supervised work as a phlebotomist, one year within the last three years or two years within the last five.
Both routes add the documented draws: 30 venipunctures and 10 capillary sticks on live people. Some states license phlebotomists themselves and add their own requirements; California is the best known example. Check your state before you book.
Booking, test day and results
You register and pay in your NHA account, then choose a test center appointment or a remotely proctored session. Bring the identification the handbook lists; for remote testing, the room and computer checks come first. The score report shows your scaled score and your performance by domain, which tells you where to work if a retake is needed.
Retakes and renewal
| Rule | NHA policy |
|---|---|
| Wait after a failed attempt | 30 days |
| Attempts at that rhythm | 3 |
| After that | One attempt a year |
| Renewal | Every 2 years, 10 continuing education credits |
The fees and retakes page compares these rules with the other certifiers, and the retake calculator above works out the wait for any exam.
What the test plan expects you to do
The CPT test plan is written as tasks rather than topics: verify the requisition, identify the patient, choose the site and the equipment, perform the collection, label at the bedside, process and transport the specimen, and handle an exposure or a reaction. Read it once before your final week: every question on the exam traces back to one of those tasks, and the mock's domain report tells you which group of tasks needs work.
This site is not the NHA and has no role in registration, scoring or certification. The questions are written by us from the test plan topics and are not questions from the real exam.
