Certified Phlebotomy Technician Exam Day Checklist
What the morning of your CPT exam looks like
The NHA Certified Phlebotomy Technician (CPT) exam is scheduled in 3-hour windows at PSI or Pearson VUE testing centers. You will spend about 30 minutes in check-in and ID verification, 2 hours on the 100-question exam, and 10 minutes on a post-exam survey. The whole visit takes about 3 hours from arrival to departure.
Most candidates arrive 30 minutes early to handle check-in. The check-in process is faster than you think if you bring the right documents, but missing one item can delay your start time or disqualify you from the day.
What to bring to the test center
Bring exactly these items and nothing else. PSI and Pearson VUE have strict no-bag policies and most personal items must be stored in a locker.
| Item | Required | Notes | |------|----------|-------| | Government-issued photo ID | Yes | Driver's license, passport, or state ID. Must be unexpired. | | Second form of ID | Yes | Social Security card, credit card, or employee ID | | Authorization-to-Test (ATT) letter | Yes | Printed or digital copy from NHA | | Confirmation number | Yes | The 9-digit number from your scheduling email | | Light jacket or sweater | Optional | Test centers vary in temperature |
Pro Tip: Use two forms of government ID if you have them
A driver's license plus a passport card works better than a driver's license plus a credit card because both are government-issued and unexpired. PSI is strict about photo ID matching your registration name exactly — if your name has changed since registration, bring the legal documentation.
What NOT to bring
| Item | Status | Reason | |------|--------|--------| | Cell phones | Prohibited | Even in airplane mode | | Smart watches and fitness trackers | Prohibited | Including Apple Watch, Fitbit | | Bags, purses, and backpacks | Prohibited | Must be stored in locker | | Food and drinks | Limited | Water in a clear bottle is allowed | | Notes, study materials, and flashcards | Prohibited | Cannot reference during exam | | Headphones and earbuds | Prohibited | Including noise-cancelling | | Hats and hoods | Prohibited | Religious headwear is allowed |
If you bring prohibited items, you will be asked to store them in a locker or leave them in your car. You will not be able to access them during the exam.
The CPT exam format
The NHA CPT exam is a 100-question computer-based multiple-choice test. The questions are not adaptive — every candidate sees the same 100 questions in a randomized order. You have 2 hours to complete the exam, which gives you about 1 minute and 12 seconds per question.
The exam covers seven content domains:
| Domain | Approximate weight | |--------|-------------------| | Venipuncture | 40% | | Capillary Puncture | 15% | | Specimen Handling | 15% | | Anatomy and Physiology | 10% | | Safety and Infection Control | 10% | | Patient Identification | 10% |
The exam is scored on a scale of 100 to 500, with 390 being the scaled passing score (equivalent to roughly 70% raw correct).
What to expect during the exam
Once seated, you will see the welcome screen. Read it carefully — it explains the flag-for-review feature and the clock display. The clock counts down even when you are on the flag-for-review screen, so do not over-flag questions.
You can flag questions for review and return to them before submitting. Use this feature sparingly: if a question is genuinely uncertain, flag it and move on, but do not flag more than 15 questions.
Watch Out For: The "two correct answers" trap
CPT exam writers occasionally include questions where two answers are technically true but only one is the best answer. The trap is to pick the more general answer (always true) instead of the more specific answer (the test writer's intent). Read each answer choice for scope, and pick the most specific correct answer.
After the exam
When you click Submit, you will see a preliminary pass/fail result on the screen. The official score report arrives by email within 24 hours. The preliminary result is highly accurate (correlates >99% with the official report), so you can rely on it for planning.
If you pass, NHA emails your CPT certificate within 7-10 business days. If you do not pass, the score report includes a domain-by-domain breakdown showing which areas need more work before a retake.
The 48 hours before exam day
The day before the exam should be light review only. Re-read your notes on the order of draw (yellow, light blue, red, green, lavender, gray, royal blue), the venipuncture complications, and the special-population considerations. Do not start any new content, and stop studying by 6 PM. Sleep 8 hours. Eat breakfast on exam day.
