- Retakes through Scantron cost $50 each, though additional NAPNES reauthorization charges may apply.
- The optional NAPNES-linked preparation course is listed at $395 for 45 contact hours.
- Certification lasts three years; the live FAQ lists renewal at $50 for members and $100 for nonmembers.
What You Are Actually Paying For
Before looking at dollar figures, it helps to be precise about the credential. Pharmacology Certification (NCP) is awarded by NAPNES, the National Association for Practical Nurse Education and Service, Inc. Successful candidates are styled LPN, NCP or LVN, NCP, meaning NAPNES Certified in Pharmacology. It is a practical/vocational-nurse certification. It is not NCLEX-PN licensure, it is not an RN specialty board, and it is not the same thing as NAPNES IV Therapy or Long-Term Care certification. If you want a refresher on the credential itself, see What Is NCP Certification? and What Does NCP Stand For?.
That distinction matters for budgeting because every fee below is paid to NAPNES or its testing vendor for this one credential. Fee figures for other certifications that happen to share the acronym have no bearing on your costs. Everything in this article traces to the NAPNES certification page, its application packet, and the preparation-course materials NAPNES links directly.
The cost question has three layers: the mandatory fees to sit the exam and receive the credential, the optional spending on preparation, and the recurring cost of keeping the certification active. Most candidates only budget for the first layer, which is why second and third layers deserve their own sections.
The Core Fee Stack: $160 on a First Attempt
According to the NAPNES FAQ, the mandatory entry cost for a first attempt is built from two line items:
| Fee Component | Amount | When It Applies |
|---|---|---|
| NAPNES registration | $100 | Once, at the start of the process |
| First-attempt testing fee | $60 | First sitting of the online exam |
| Combined first-attempt cost | $160 | Before any optional preparation |
The exam is a timed online examination delivered through Scantron, with 150 multiple-choice questions and a 75% passing requirement. The exact current exam duration could not be verified from the sources available, so check the NAPNES certification page for the latest timing rather than relying on a number from a forum post. Importantly, the 45 contact hours attached to the preparation course are course hours, not exam hours.
Eligibility Is a Cost Issue Too
Normal certification requires an active, unencumbered U.S. or U.S.-territory LPN/LVN license. The linked NAPNES rules allow special review of probationary licenses, so a restricted license is not automatically disqualifying, but you should confirm your status before paying anything. Students in approved school programs may test before they are licensed, but their certification stays pending until licensure and the other issuance requirements are completed. The full picture is laid out in NCP Requirements: Eligibility, Prerequisites and How to Qualify.
Passing the Exam Is Not the Finish Line
After you pass, you must complete the notarized affidavit and application process. The application instructs that the affidavit be returned within 60 days of receipt. Certification is not complete merely because the exam was passed. Notarization is typically a small out-of-pocket expense, and mailing costs add to it, so budget a few dollars for that final step and calendar the 60-day deadline the day your results arrive.
What a Retake Costs
If you do not reach the 75% threshold on your first attempt, the NAPNES FAQ lists subsequent Scantron attempts at $50 each. That is cheaper than the $60 first-attempt fee, but it comes with a caveat: additional NAPNES reauthorization charges are possible. The sources do not give a firm figure for those charges, so contact NAPNES to confirm the total before you rebook.
A realistic worst-case entry cost looks like this: $100 registration, $60 first attempt, then $50 for each additional attempt, plus any reauthorization fees NAPNES assesses. Even with two retakes, the exam fees stay modest compared with many professional credentials. The expensive mistake is not the retake fee itself but the time lost and the possibility of an expired authorization.

The Optional $395 Preparation Course
NAPNES directly links its authorized online provider, Online Education Programs, for the NAPNES Pharmacology Certification Course. The course is listed at $395 for 45 contact hours. Its public description covers medication administration, dosage calculations, nursing mathematics, IV-fluid rates, and safety and documentation.
Two honest caveats belong here. First, the course is optional; the fee sheet does not require it. Second, the product page conflicts on access length, showing both 360 days and six months in different places, so neither should be treated as definitive. Confirm the access period at checkout, especially if you plan to start slowly. The paid lessons and the restricted course FAQ could not be reviewed, so any claim about lesson quality beyond the public syllabus would be speculation.
The public syllabus describes the curriculum as ten clinical preparation units across sixteen modules. These are unweighted preparation topics, not an official exam blueprint, but they give you a good map of what the money buys:
The Ten Preparation Units
These are the curriculum headings you would work through in the course, and they also make a sensible checklist if you self-study instead.
- Domain 1: General Principles of Pharmacology
- Domain 2: Pharmacology and the Role of the LP/VN
- Domain 3: Drug Therapy Affecting the Nervous System
- Domain 4: Drug Therapy Affecting Kidney and Body Fluid Composition
- Domain 5: Drug Therapy Affecting the Cardiovascular System
- Domain 6: Drug Therapy in Infection
- Domain 7: Drug Therapy in Cancer
- Domain 8: Drug Therapy Affecting the Gastrointestinal System and Nutrition
- Domain 9: Drug Therapy Affecting Respiratory Function
- Domain 10: Drug Therapy Affecting Endocrine and Reproductive Function
A note on a small inconsistency: the syllabus prose refers to eight units, but the fully visible curriculum enumerates Units 1 through 10. The ten headings above are the ones the public material actually supports. For a deeper walk through each area, see NCP Exam Domains: Complete Guide to All 10 Content Areas.
Course Versus Self-Study
Because the exam fee is only $160, the preparation course at $395 is more than twice the cost of sitting the test. That ratio is exactly why the decision deserves thought rather than reflex. A candidate who works daily with medication administration, performs dosage calculations routinely, and has recent pharmacology coursework may reasonably self-study with a structured plan, such as the one in the NCP Study Guide. A candidate who has been out of school for years, or whose job rarely touches IV-fluid rates and nursing math, may find a guided 45-hour course easier to commit to. See NCP Training for more on the formal options.
Costs That Do Not Appear on the Fee Sheet
The published fees cover only what NAPNES and its vendor charge. Several real expenses sit outside them:
- Notarization and mailing for the affidavit and application you must return after passing.
- Reference materials such as a current nursing drug handbook or dosage-calculation workbook, if you are not taking the course.
- A reliable computer and internet connection for a timed online exam, since a failed session can cost you an attempt.
- License verification or renewal if your LPN/LVN license is near expiration, because an active, unencumbered license is the baseline requirement.
- Practice testing, which many candidates add on their own. Our main practice test site offers question-style practice if you want to gauge readiness before spending on a formal attempt.
Renewal Costs Every Three Years
The certification lasts three years, so the true lifetime cost includes renewal. The live NAPNES credential FAQ lists standard renewal fees of $50 for members and $100 for nonmembers. If you choose to renew by reexamination, testing fees are additional.
The NAPNES Pharmacology Re-Certification Candidate Information packet, which carries a legacy 2009 filename but is still linked by the issuer, describes two paths:
- Reexamination, which means sitting the test again and paying the associated testing fee on top of renewal.
- A continuing-education route, which requires one of the following within the renewal period: 24 contact hours including at least eight pharmacology hours, or 50 clinical-nursing contact hours, or three semester hours of pharmacology.
The continuing-education route also requires 1,500 nursing-practice hours involving routine medication administration during the preceding three years. This is a renewal condition only; it is not a prerequisite for the initial exam. The packet also instructs candidates to apply at least 60 days before expiration, which is the practical way to avoid late-fee exposure.
Key Takeaway
Use only the live FAQ figures ($50 member, $100 nonmember) for standard renewal budgeting. Legacy documents conflict on late fees and contain a corrupted member-fee field, so do not rely on old packet numbers for penalties. Renew at least 60 days early and the late-fee question never becomes your problem.
The CE route can be cost-efficient if your employer already pays for continuing education, since the contact hours may cost you little beyond what you would complete anyway. Reexamination is simpler on paper but adds testing fees and requires you to relearn the material. Which is cheaper depends on your employer benefits and how current your pharmacology knowledge is.
Three Realistic Budget Scenarios
Combining the verified figures gives three plausible profiles. These show only fees stated by NAPNES and its linked course provider; your personal extras will vary.
| Scenario | Known Fees | Approximate Total |
|---|---|---|
| Self-study, pass on first attempt | $100 registration + $60 first attempt | $160 |
| Self-study, one retake | $100 + $60 + $50 (plus possible reauthorization) | $210 or more |
| Course plus first-attempt pass | $395 course + $100 + $60 | $555 |
| Add standard renewal (member), any scenario | + $50 every three years | Adds $50 per cycle |
The gap between $160 and $555 is almost entirely the course. That is the single largest discretionary decision in the whole process. If cost is your main constraint, the question to ask is not "Can I afford the course?" but "Which candidates in my situation actually benefit from it?" For the career-side math that justifies any of these totals, see Is the NCP Certification Worth It? and the NCP Salary Guide.

Where Prep Money Pays Off Most
If you do spend on preparation, concentrate it where this particular exam rewards you. The preparation curriculum emphasizes dosage calculations, nursing mathematics, and IV-fluid rates, and these are the topics where a candidate's mistakes are most mechanical and most fixable. Early in your plan, give extra time to Domain 1 (General Principles of Pharmacology) and Domain 2 (Pharmacology and the Role of the LP/VN), since they frame how everything else is tested. Then schedule the system-based drug domains, beginning with Domain 5 (cardiovascular) and Domain 3 (nervous system), which typically carry the densest drug lists.
Foundations and Scope of Practice
- Domain 1: General Principles of Pharmacology
- Domain 2: Pharmacology and the Role of the LP/VN
- Dosage calculation drills, since these underpin every later domain
High-Density Drug Systems
- Domain 3: nervous system drug therapy
- Domain 5: cardiovascular drug therapy
- Domain 4: kidney and body fluid composition, including IV-fluid rate practice
Remaining Systems
- Domain 6: infection; Domain 7: cancer
- Domain 8: GI and nutrition; Domain 9: respiratory
- Domain 10: endocrine and reproductive function
Timed Practice Before You Pay for Authorization
- Full-length practice sets in a 150-question format
- Target comfortably above the 75% line before you register
The sequencing logic is financial as well as pedagogical: because your authorization runs for 60 days, you want to be well past the passing line in practice before you activate it. Registering first and studying second is the pattern most likely to turn a $160 exam into a $210 or $260 one. A quick one-page review such as the NCP Cheat Sheet is a low-cost way to check gaps in the final days, and the practice test hub lets you rehearse the multiple-choice format without spending an attempt.
