The NHA Certified Phlebotomy Technician (CPT) exam is a two-hour, 120-item computer-based test covering Safety and Compliance, Patient Preparation, Routine Blood Collections, Special Collections, and Processing. To sit for it you need a high school diploma or equivalent, a qualifying training program or supervised work experience, and documented evidence of 30 venipunctures and 10 capillary or finger sticks on live individuals. This guide explains those requirements, how the scaled score of 390 works, what each domain contains, and how to build your study plan around the official test plan.
Which exam version applies and what it certifies
The CPT is NHA's entry-level phlebotomy certification exam, and the current version has applied to every attempt since January 7, 2026.
The National Healthcareer Association (NHA) designs each certification exam to evaluate the knowledge and skills required for entry-level practice in the credential's field, and its certification programs are accredited by the National Commission for Certifying Agencies (NCCA). The CPT is one of eight NHA certifications listed in the Candidate Handbook.
NHA introduced the current CPT exam on January 7, 2026. Use its free test plan, based on the 2024 job analysis, with the Candidate Handbook updated June 1, 2026. Check older books and forum advice against those documents before using them to plan your study.

Eligibility: diploma, pathway, and stick counts
For the standard route, check three requirements: your diploma or equivalent, qualifying training or work experience, and documented successful collections on live people. Separate conditional routes apply to some students.
Step one is a high school diploma or a recognized equivalency such as a GED. Step two is one of two pathways: complete a training program in the relevant health field within the past five years (including an accredited program, a registered apprenticeship, military medical training, or qualifying employer-based training), or show at least one year of supervised work experience within the last three years, or two years within the last five.
Step three is specific to phlebotomy: you must provide evidence that you have successfully performed a minimum of 30 venipunctures and 10 capillary or finger sticks on live individuals. This requirement applies before you sit for the exam, unless your institution agreed to the pre-externship route, which lets you test after coursework but before your externship. In that case your certificate is held back until your institution confirms externship completion within 90 days of the exam date; otherwise the passing score is voided.
If you are still in high school, a Provisional Certification lets you test up to 12 months before graduation. It expires 12 months after the exam date, cannot be renewed, and must be converted to full certification with proof of graduation. You must register yourself; no one else can register on your behalf.
Finally, NHA certification is separate from state law. State rules on practicing phlebotomy vary, NHA certification does not guarantee you meet any state's regulatory requirements, and you are responsible for checking your state's oversight body.

Format, scoring, and reading your score report
Expect 100 scored items plus 20 unscored pretest items in two hours, scored on a 200-500 scale where 390 or higher passes.
The exam is computer-based and taken at a PSI testing center, via live remote proctoring, or at your institution if it is an authorized site. NHA uses a scaled score so that the passing standard stays consistent across exam forms: scores range from 200 to 500 and 390 or higher passes. A scaled score of 390 is not a raw score of 390 out of 500, and it does not mean you must answer 78% of questions correctly.
Score availability depends on where you test. Preliminary results appear immediately for exams taken at your institution, while PSI center and live remote proctoring results post within 48 hours. Preliminary results are not final results, and using them as proof of certification for employers is at your own risk until the formal certificate is issued.
Your score report also places your performance in each major content area into three categories: above, near, or below the passing standard. A content area with five or fewer questions gets an 'N/A' instead, because so few items cannot support a reliable category. If you fail, NHA advises focusing retake study on the areas rated below or near the standard, without excluding the above-standard areas, since each category is a range rather than a precise level.

The five tested domains and the core knowledge layer
The exam draws 100 scored items from five domains, with a set of core-knowledge statements that can appear in any domain.
The 2025 test plan, built on the 2024 job analysis, organizes scored content into five domains. The weights below are fixed item counts per 100 scored questions, so Routine Blood Collections carries the most items and Special Collections the fewest.
Before the domains, the plan lists Core Knowledge: statements such as blood components and blood group systems, cardiovascular and phlebotomy-related vascular anatomy, hemostasis, aseptic technique, Standard Precautions, HIPAA and patient rights, communication and cultural considerations, professionalism, and labeling and documentation requirements. These are not a standalone domain; items can draw on them anywhere, so review them alongside every domain rather than as a separate chapter.
| Domain | Scored items | Share |
|---|---|---|
| 1. Safety and Compliance | 26 | 26% |
| 2. Patient Preparation | 20 | 20% |
| 3. Routine Blood Collections | 28 | 28% |
| 4. Special Collections | 12 | 12% |
| 5. Processing | 14 | 14% |
How to prepare against the current test plan
Use the detailed test plan as your checklist, confirm your study materials match the January 2026 exam version, and drill the tasks where you are weakest.
Download the test plan and mark each task as familiar, uncertain or unfamiliar. Then try a relevant practice question or instructor-approved case. Use the result to check your confidence: explain the answer and locate the supporting rule in your current course or procedure reference.
NHA’s study materials are optional and do not guarantee passing. When time is short, use your practice errors to select the next task to review instead of collecting more study products. Check that your material supports the exam introduced in January 2026.
The larger domains contain more scored items overall, but the plan does not establish how many questions will address any individual subtopic. Use both the domain weights and your demonstrated weaknesses when planning study time.
| Domain | Suggested review task |
|---|---|
| Safety and compliance | Review a course scenario about infection control, exposure or patient rights; explain the relevant rule using your current reference. |
| Patient preparation | Work through an identification, consent or test-preparation scenario and identify the information you need to verify. |
| Routine blood collections | Review the course rationale for equipment selection and specimen requirements; ask your instructor to resolve any procedural uncertainty. |
| Special collections | Compare the purposes and requirements of the special tests named in the plan using your course references. |
| Processing | Trace a sample specimen through labeling, handling, transport and processing; identify where an error would make it unsuitable. |

Retakes, fees, and keeping the credential
Retakes require a waiting period and the full exam fee. Once certified, renew every two years with the required continuing education and fee.
After the first or second failed attempt, wait at least 30 days before retesting. After the third failed attempt and each later failure, wait one year before another attempt. Each retake requires a new registration and the full exam fee; three attempts is not a lifetime limit.
The exam fee itself is not stated in the handbook: NHA lists applicable exam fees on its website shop pages, and the amount can vary by product or package, so check the current fee there before registering.
Once you pass, the certification is valid for two years from the date shown on the certificate. Renewal requires completing 10 continuing education credits and paying the recertification fee before expiration; there is no penalty for renewing early, and if a certification lapses you have one year to reinstate it.
