- PSNCB's C-NET exam is 150 multiple-choice items (about 25 unscored), roughly three hours, computer-based via PSI.
- Aesthetic injectables is the single largest clinical area at 55% - build your review around it first.
- Passing uses Angoff standard-setting, described as approximately 75% correct, not a fixed universal cutoff.
- Fees are $325 for current ISPAN members or $495 for nonmembers, with a $25 nonrefundable portion.
What CANS Actually Means (No Confusion)
In this article, and everywhere on this site, CANS refers exclusively to the Certified Aesthetic Nurse Specialist credential administered through C-NET, the computer-based testing program overseen by the Plastic Surgical Nursing Certification Board (PSNCB). If you've landed here after seeing other acronyms floating around the internet that also happen to be "CANS," ignore them - none of the facts on this page apply to those credentials. If you want the full backstory on the title itself, our companion pieces on What Is CANS?, CANS Meaning, and What Does CANS Stand For? walk through the terminology in more depth.
This cheat sheet is meant to be the single page you reread the night before your test date, or the morning of, when you don't want to dig back through a 40-page study guide. It consolidates the exam-development facts, domain weights, eligibility rules, and renewal mechanics into one scannable reference. For deeper prep, pair this with the full CANS Study Guide 2026: How to Pass on Your First Attempt.
Exam Snapshot: Format, Timing, Scoring
Here's the exam in numbers, pulled straight from the official exam-development documentation and application materials:
| Detail | Specification |
|---|---|
| Administering body | Plastic Surgical Nursing Certification Board (PSNCB), via C-NET |
| Delivery | Computer-based, year-round, through PSI testing centers |
| Question count | 150 multiple-choice items (about 25 unscored pilot items included) |
| Time allotted | Approximately three hours |
| Scoring method | Angoff standard setting; described as roughly 75% correct rather than a fixed cutoff |
| 2023 pass rate | 95% (62 of 65 candidates, including recertification candidates) |
Key Takeaway
Don't panic over unscored pilot items - you won't know which of the 150 questions count, so answer every item as if it does. Pacing across roughly three hours means budgeting well under a minute per question on average.
For a deeper breakdown of what "about 75% correct" actually implies for your study threshold, see CANS Passing Score 2026: Exactly What You Need to Pass. And if you're trying to gauge how tough this really is relative to your clinical background, How Hard Is the CANS Exam? Complete Difficulty Guide 2026 and CANS Pass Rate 2026: What the Data Shows go into more context around that 95% figure.
The Three Domains, Weighted Correctly
The clinical practice content is organized into three domains. Memorize these weights - they should directly shape how many hours you spend on each topic.
Domain 1: Aesthetic Injectables - 55%
The largest domain by far, covering neuromodulators, dermal fillers, patient assessment for injectable candidacy, complication recognition, and technique-related safety.
- Mechanisms of action for common neuromodulators and filler classes
- Recognizing and managing vascular occlusion and other injectable complications
- Pre- and post-procedure patient counseling for injectable treatments
Domain 2: Laser, Light, and Energy-Based Therapies - 30%
Covers device categories, tissue interaction principles, candidacy screening, and safety protocols for energy-based aesthetic treatments.
- Laser/light physics basics as they apply to skin and tissue targets
- Fitzpatrick skin typing and its role in device settings and candidacy
- Pre-treatment screening and post-treatment care for energy-based modalities
Domain 3: Clinical Skin Care - 15%
The smallest domain, but still tested - covering topical regimens, chemical peels, and general skin health assessment.
- Ingredient categories and appropriate use in pre/post-procedure regimens
- Peel depth classification and associated risk factors
- Skin assessment fundamentals tied to treatment planning
Eligibility Requirements at a Glance
Before you can even sit for the exam, PSNCB requires documentation across several fronts. This is often the part candidates underestimate - gathering letters and hour logs takes longer than reviewing content.
- An unrestricted RN, NP, or APRN license (US, US territorial, or Canadian) appropriate to your role
- 1,000 core-specialty practice hours completed within the preceding two years
- Two years of relevant RN experience within the preceding three years
- Current qualifying practice or collaboration arrangement, plus recommendation letters
- Additional documentation for NP and NP-supervised applicants beyond the standard RN pathway
Full detail on each requirement, including how the hour logs and letters should be formatted, is covered in CANS Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Fees, Registration, and Testing Windows
Once your application is approved, here's what to expect financially and logistically:
| Item | Detail |
|---|---|
| Fee - current ISPAN members | $325 USD |
| Fee - nonmembers | $495 USD |
| Nonrefundable portion | $25 of the total fee |
| Testing authorization window | 90 days once PSI authorization is issued |
| Testing availability | Year-round, computer-based, at PSI centers |
Once your 90-day PSI authorization opens, schedule promptly - waiting reduces your buffer for rescheduling around work shifts. See CANS Exam Dates 2026: Testing Windows, Deadlines & Scheduling for how to plan around that window, and CANS Certification Cost 2026: Complete Pricing Breakdown for a full cost picture including any add-on expenses.
Key Takeaway
Note that the $25 nonrefundable portion applies regardless of member status - factor that into your decision timeline before submitting payment.
Certification Length and Renewal
CANS certification is valid for three years. To renew by continuing education, you need:
- 45 total contact hours
- At least 30 of those hours in core-specialty content
- At least 2 hours specifically in patient safety
- Continued eligibility per PSNCB standards
- Renewal fee of $200 for members or $350 for nonmembers
Examination is offered as an alternative renewal route if you'd rather retest than log CE hours. Neither PSNCB nor C-NET offers or endorses an official practice test, which is exactly why structured third-party prep - like the practice questions available on our main practice test platform - matters for closing that gap.
A Compressed Final-Review Week
If you're using this cheat sheet in the final stretch before your test date, don't spread review evenly across domains - weight your remaining hours the same way the exam weights content.
Aesthetic Injectables Deep Review
- Redo every injectable complication scenario you've flagged as weak
- Drill neuromodulator vs. filler indication differences
Laser, Light, and Energy-Based Therapies
- Review Fitzpatrick typing and device candidacy logic
- Run through pre/post-treatment protocol checklists
Clinical Skin Care
- Cover peel depth classifications and ingredient categories
- Skim rather than deep-dive - this is your lightest-weighted domain
Mixed Review + Logistics
- Take a full-length timed practice run on the practice test site
- Confirm PSI appointment, ID requirements, and travel time
This isn't a generic Pomodoro-and-flashcards template - it's specifically sequenced so the domain worth 55% of the exam gets the most days, the 30% domain gets the next block, and the 15% domain gets a lighter final pass. For a longer runway version of this plan spanning several weeks, see the full CANS Study Guide 2026.
Frequently Asked Questions
The exam contains 150 multiple-choice questions, including about 25 unscored pilot items, administered over approximately three hours at a PSI testing center.
Aesthetic Injectables, at 55% of the Clinical Practice Areas axis, is by far the largest domain - it deserves the majority of your review time relative to Laser, Light, and Energy-Based Therapies (30%) and Clinical Skin Care (15%).
No. PSNCB and C-NET do not offer or endorse a practice test, which makes independent prep resources, like the questions on our practice test platform, a useful supplement to your own study materials.
PSNCB uses Angoff standard setting, which the board describes as roughly 75% correct rather than a guaranteed, unchanging cutoff score applied to every exam form.
CANS certification lasts three years. Renewal by education requires 45 contact hours (at least 30 core-specialty and 2 patient-safety hours), continued eligibility, and a $200 member or $350 nonmember fee; retaking the exam is an alternative renewal path.
