CPT · CET
The Certified Phlebotomy Technician (CPT) and Certified EKG Technician (CET) are two of the most widely-required allied-health entry credentials from the National Healthcareer Association. Hospitals, clinics, blood-donation centers, and staffing agencies routinely list one or both as a hiring condition for draw-station and cardiac-monitoring roles, and several states fold the NHA into their hiring or licensure expectations. A failed attempt means another fee, another waiting period, and a delayed start date — this page breaks down exactly what each exam tests, how it's delivered, and how to clear it the first time.

Two NHA credentials, the same exam engine — pick the one your role requires (or both)
| Credential | Code | Clinical requirement | Who it's for |
|---|---|---|---|
| Certified Phlebotomy Technician | CPT | 30 venipunctures + 10 capillary/finger sticks on live individuals | Draw stations, labs, plasma/blood-donation centers, mobile draw teams |
| Certified EKG Technician | CET | 10 EKGs performed on live individuals | Cardiology units, stress-test labs, telemetry, physician offices |
Both exams share the same structure — 120 items, a two-hour limit, and a 200–500 scaled score with a 390 cut score — but they test entirely different skill sets. Many allied-health programs prepare students for both so graduates can take a draw-and-EKG combination role, which is why this page covers the CPT and CET together.
How the CPT and CET are built — at a glance
120
Each exam has 120 four-option multiple-choice items: 100 are scored and 20 are unscored pretest questions NHA seeds in to trial future items. You can't tell which is which, so every question gets your full attention.
2h
A flat two-hour window — about one minute per item. There's no separate practical exam inside the test; the clinical draws and EKGs are verified through your program or work experience beforehand.
390
Your raw score on the 100 scored items is converted to a 200–500 scaled score, and 390 is the cut. Because scaling adjusts for form difficulty, the exact number of correct answers needed shifts slightly between versions.
Both exams run linearly — not adaptive — so you can flag items and revisit them within the two hours. Computer-based results are typically available very quickly; for PSI-center and Live Remote Proctoring sittings, NHA usually posts your official result to your account within about two days.
The CPT is heavy on order-of-draw, additive tube colors, and pre-analytical errors — small details that cost real points. The CET demands fast, accurate rhythm recognition and 12-lead placement under time pressure. Both lean on distractor answers that look right if you skimmed your notes.
Five phlebotomy domains — bars show each domain's approximate share of the scored items
Routine venipuncture technique, vein selection, equipment assembly, order of draw, and tube inversion — the core daily work of a phlebotomist.
Labeling, transport, centrifugation, and the pre-analytical errors — hemolysis, clotting, mislabeling — that invalidate a sample.
Infection control, PPE, sharps disposal, OSHA bloodborne-pathogen rules, HIPAA, and patient identification protocols.
Capillary/finger sticks, blood cultures, glucose tolerance, blood smears, and pediatric or geriatric draw considerations.
Patient identification, consent, communication, fasting requirements, and managing anxious or difficult patients before a draw.
Domain weights are approximate and follow NHA's published CPT test plan; the largest share sits in routine collections and specimen integrity, which is exactly where most failed candidates lose points. Confirm the current blueprint in your NHA candidate handbook before test day.
Three EKG domains — bars show each domain's approximate share of the scored items
12-lead placement, electrode prep, troubleshooting artifact and wandering baseline, and acquiring clean tracings on real patients.
Patient care, infection control, equipment maintenance, documentation, HIPAA, and coordinated-care responsibilities around cardiac monitoring.
Calculating heart rate, determining rhythm regularity, and recognizing common arrhythmias and waveform abnormalities from the tracing.
The CET leans heavily on acquisition and safety, but the interpretation domain is where most candidates feel the squeeze — distinguishing atrial fibrillation from flutter, or normal sinus rhythm from a heart block, under exam pressure. Confirm the current CET blueprint in your NHA candidate handbook before test day.
Three ways to sit the NHA exam — and what to expect on test day
You can sit the CPT or CET at a PSI testing center or, if you trained through an approved school, at your program's proctored site. Staff verify your government photo ID, store your belongings, and monitor the room for the full two hours. Center results are usually available very quickly.
You take the exam from a private room at home with NHA's Live Remote Proctoring. A live proctor watches you through your webcam after a system check, ID verification, and room scan. You'll need a quiet space, a stable connection, and a working camera and microphone for the full session.
A valid, unexpired government photo ID whose name matches your NHA registration exactly. The proctor captures your photo and verifies your identity before the exam unlocks.
A clear desk, no second monitor, no phone or notes within reach, and a webcam scan of the room. No one else may enter, and headphones are typically not allowed.
Stay in frame and on-camera throughout. Looking off-screen, talking aloud, leaving your seat, or losing connection can pause or flag your Live Remote session.
The CPT and CET are entry credentials for allied-health roles
There are real prerequisites — and the details bite
Difficulty: Neither exam is conceptually advanced, but both punish shallow study. Order of draw, tube additives, and pre-analytical errors trip up CPT candidates; rhythm interpretation and lead placement trip up CET candidates. With a fee on every retake and a wait between attempts, getting it right the first time is exactly the pressure point our help is designed to remove.
The CPT and CET are detail-dense, fee-on-every-retake exams standing between you and a healthcare job offer. Exam Assist pairs you with a vetted allied-health specialist and works on a pay-after-you-pass model — so the risk sits with us, not you. No upfront fee, guaranteed results: Exam Assist handles the sitting end to end, and you settle only after the verified result.
