About this exam

The Certified Phlebotomy Technician (CPT) credential is offered by the National Healthcareer Association (NHA), an allied health certification agency that has awarded over 1 million nationally recognized certifications and states that its exams are NCCA-accredited. The CPT is aimed at people who draw blood from patients and blood donors and who prepare blood, urine and other specimens for testing. NHA describes the role as including drawing blood, evaluating whether a patient can withstand the procedure, explaining the procedure and answering questions, performing basic point-of-care testing such as reading blood glucose levels, preparing specimens, and maintaining equipment such as needles, test tubes and blood vials. Employers hire CPTs in hospitals, diagnostic laboratories and blood donor centers. To sit the exam you need a high school diploma or equivalency (or be scheduled to earn one within 18 months), a phlebotomy training program completed within the last 5 years, and documented evidence of at least 30 venipunctures and 10 capillary or finger sticks on live individuals - or, alternatively, supervised phlebotomy work experience (1 year within the last 3, or 2 years within the last 5). The exam is two hours long and can be taken at your school, at a PSI testing center, or through live remote proctoring. NHA sells an online study guide, a practice test with up to six attempts, a preparation package and a free test plan; preparation materials are optional and do not guarantee a passing score. Certification is renewed every two years with 10 continuing education credits and a recertification fee.

What you'll study

Common questions

About CI-CPT preparation

How long is the CPT exam and where can I take it?

NHA states the exam is two hours long. You can take it at your school, at a PSI testing center near you, or through live remote proctoring at a location of your choice. You pick the date and location when you schedule, and an exam payment is required at that step.

What are the eligibility requirements before I can sit the exam?

You need a high school diploma or GED/high school equivalency (or be scheduled to earn one within 18 months), a phlebotomy technician training or education program completed within the last 5 years, and evidence of at least 30 venipunctures and 10 capillary or finger sticks on live individuals. Supervised work experience can substitute on the alternate pathway.

What does NHA say about how hard the exam is or what score passes?

The public CPT page does not publish a passing score, a question count, or a difficulty rating, so treat any specific number you hear as unofficial. NHA points candidates to the Candidate Handbook for eligibility and exam details. Build your study plan around the tasks NHA lists for the role rather than around rumored cutoffs.

Can I retake the exam if I fail, and how many practice test attempts do I get?

The CPT page does not state an exam retake policy, so confirm it with NHA directly before you rely on one. It does state that the phlebotomy practice test comes with up to six attempts. The practice test is based on the actual exam, but NHA notes that using preparation materials does not guarantee a passing score.

How soon do I get my results?

For online exams, NHA says it will officially post your certification results to your account page within two days of scoring your test. Results are posted to your NHA account, so make sure your account is set up and that you selected your school or employer if you want results shared with them.

What should I study first, and what do phlebotomy techs actually do?

Start with the tasks NHA lists: drawing blood from patients and donors, judging whether a patient can withstand the procedure and keeping them comfortable, explaining the procedure and answering questions, basic point-of-care testing such as blood glucose, preparing blood and urine specimens, and maintaining needles, tubes and vials. The free CPT Test Plan maps key concepts.

What soft skills do employers look for, and is certification required?

NHA reports that 96% of employers require or encourage certification for phlebotomy technicians (2025 Industry Outlook) and that professionalism and dependability are the soft skills employers value most when hiring a phlebotomy technician. Expect scenario questions about bedside manner, consent and clear patient communication.

How do I keep my CPT after I pass?

Certifications must be renewed every two years. Before your expiration date you complete 10 continuing education credits and pay your recertification fee; NHA describes the cost as $8 per month and says there is no penalty for renewing early. If your certification has expired, you have 1 year to reinstate it.

What does the certification cost and how is the exam application submitted?

The CPT page does not list an exam fee, so check your NHA account for current pricing and any school or employer discounts. You apply by creating a free NHA account online and submitting the CPT exam application through your account portal; payment is required when you schedule your date and location.

Is this page affiliated with NHA?

No. This is an independent study resource and is not affiliated with, endorsed by, or sponsored by the National Healthcareer Association. Always confirm eligibility, fees, scheduling and renewal rules against NHA's official CPT page and Candidate Handbook before making decisions.
