- Version 1.2 has 100 scored items, a 150-minute limit, and four domains: Assessment, Evaluation, Implementation, Planning.
- There is no NLN-set passing score - each nursing program sets its own acceptance or placement standard.
- Testing happens on NLN Assess (Assess.ai), proctored on campus or virtually through Proctor360.
What Is a NACE I, Exactly?
The NACE I - formally the Nursing Acceleration Challenge Examination: Foundations of Nursing (NACE-FON) - is a standardized assessment built specifically for licensed practical and vocational nurses who are moving into an accredited professional (RN-track) nursing program. It is not a licensing exam and it is not a renewable professional certification. There's no CEU requirement and no recurring renewal cycle attached to it. Instead, it functions as an academic checkpoint: a way for nursing programs to verify that an LPN/LVN candidate has a solid grasp of foundational nursing-process content before being admitted, placed into advanced coursework, or awarded academic credit.
If you've landed here because you're comparing this credential to something else that also goes by "NACE I," it's worth being precise: this article covers only the NACE-FON developed by the National League for Nursing. For a deeper dive into terminology and naming, see NACE I Meaning and What Does NACE I Stand For?.
Who Develops and Administers the Exam
The National League for Nursing (NLN) develops the NACE-FON. The exam's current official form is Version 1.2, documented in 2023, and it remains the version most programs are using as they build admission and placement policies around it. Because NLN builds the exam but doesn't dictate a universal cutoff score, the practical meaning of "passing" varies by school - a topic covered in detail in NACE I Passing Score 2026: Exactly What You Need to Pass.
Individual nursing programs are the ones who decide how the exam is used: some use it strictly as an admissions gate, others use it for placement into specific coursework, and some use it to award academic credit for prior LPN/LVN training. That means two students taking the identical NACE-FON exam might be held to very different standards depending on which program they're applying to.
Exam Format and Testing Platform
Version 1.2 of the NACE-FON is built around 100 scored content items, with a 150-minute time limit. The exam runs on the NLN Assess platform (Assess.ai), and candidates have two ways to sit for it:
- Campus administration: faculty at the nursing program directly administer the exam on-site.
- Virtual administration: proctored one-on-one remotely through Proctor360.
If you're testing virtually, materials are tightly controlled. The only items allowed are a basic four-function calculator, a dry-erase board no larger than 8.5 by 11 inches, a dry-erase marker, and an eraser. No notes, no phones, no scratch paper beyond the approved board - plan your test-day setup accordingly. For a fuller breakdown of scheduling logistics and testing windows, see NACE I Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
The Four Nursing-Process Domains
NACE-FON content is organized around the classic nursing process, split into four domains with distinct weightings. Understanding these weights should directly shape how you divide your study time - a subject explored fully in NACE I Exam Domains 2026: Complete Guide to All 4 Content Areas.
Domain 1: Assessment (24%)
Covers a nurse's ability to gather, organize, and interpret patient data accurately.
- Recognizing relevant subjective and objective findings
- Prioritizing which data points matter most in a given scenario
Domain 2: Evaluation (23%)
Focuses on judging whether nursing interventions actually achieved the intended patient outcome.
- Comparing expected vs. actual outcomes
- Deciding when a care plan needs revision
Domain 3: Implementation (29%)
The largest single domain - centers on carrying out nursing interventions safely and correctly.
- Sequencing and executing care activities appropriately
- Applying foundational nursing skills in scenario-based items
Domain 4: Planning (24%)
Tests the ability to translate assessment data into a coherent, prioritized plan of care.
- Setting realistic, measurable goals
- Sequencing interventions by priority and urgency
Key Takeaway
Implementation carries the most weight at 29%, so if you only have time to deeply review one domain, make it this one - but don't neglect the other three, which together still make up 71% of scored content.
How Scoring Actually Works
After you finish, the NACE-FON produces a Coaching Report showing percentage-correct results for the total exam and for each of the four domains individually. This domain-by-domain breakdown is genuinely useful - it tells you exactly where your foundational knowledge is strong and where it's thin, which matters more than a single overall number.
Here's the part that surprises a lot of candidates: NLN does not set a national passing score. Each nursing program establishes its own acceptance, placement, or credit standard using your results. That means "what score do I need" isn't a question NLN answers - it's a question your specific program answers. Always confirm the standard your program uses before you test; general pass-rate discussion for context (without inventing numbers NLN hasn't published) is covered in NACE I Pass Rate 2026: What the Data Shows.
| Exam Detail | Specification |
|---|---|
| Current Version | 1.2 (documented 2023) |
| Scored Items | 100 |
| Time Limit | 150 minutes |
| Score Report | Coaching Report - total % + 4 domain %s |
| Passing Score | Set by individual program, not NLN |
| Testing Platform | NLN Assess (Assess.ai) |
| Proctoring Options | Campus (faculty) or virtual (Proctor360) |
Registration, Fees, and Retesting Rules
Effective March 1, 2026, NACE-FON pricing breaks down as follows:
- $75 for a school-paid campus exam
- $96 for a virtual exam
- $62 for the official Foundations prep product
On retesting: NLN itself does not cap the number of attempts, but your institution may impose its own limit - so check with your program directly. If you do retest, NLN requires a 30-day wait between attempts unless your school has communicated a different frequency. Every score you earn gets reported, and NLN retains scores for three years. That last point matters: a poor early attempt doesn't disappear, so it pays to prepare seriously before your first sitting rather than treating it as a low-stakes trial run. A full cost breakdown, including how prep materials factor into total spend, is available in NACE I Certification Cost 2026: Complete Pricing Breakdown. For eligibility specifics before you register, see NACE I Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Who Takes the NACE I and Why
The candidate pool for NACE-FON is specific: licensed practical nurses and licensed vocational nurses who are either applying to an accredited professional nursing program or already admitted and working through it. Programs use the exam in a few different ways - as an admissions screen, as a placement tool to determine which courses a student can skip or must take, or as the basis for awarding academic credit for prior LPN/LVN education.
Because the exam sits at this LPN-to-RN transition point, the people evaluating your NACE-FON results aren't employers - they're nursing school admissions committees and academic advisors. If you're wondering how this connects to job prospects down the line, that's really a question about what the RN program you're targeting leads to, not about the exam itself; see NACE I Jobs and NACE I Salary Guide 2026: Complete Earnings Analysis for that broader picture, and Is the NACE I Certification Worth It? Complete ROI Analysis 2026 for a balanced look at the investment.
A Domain-Aware Way to Prepare
Generic study advice (flashcards, spaced repetition, timed drills) only helps if it's pointed at the right targets. For NACE-FON, that means anchoring your schedule to the four domain weights rather than studying everything equally.
Implementation (29%) + Assessment (24%)
- Drill scenario-based questions on executing interventions correctly
- Practice distinguishing relevant vs. irrelevant patient data
Planning (24%) + Evaluation (23%)
- Practice sequencing and prioritizing care plan goals
- Review how to judge whether an intervention met its outcome
Mixed Review + Timed Practice
- Take full-length timed sets under the 150-minute constraint
- Use Coaching Report-style self-checks to find remaining weak domains

How NACE I Compares to Other Nursing Checkpoints
It helps to be clear about what NACE-FON is not. It's not a state licensing exam, and it doesn't produce a credential you renew every few years with continuing education units. It's a one-time (or occasionally repeated) academic assessment tied to a specific admissions or placement decision at a specific school. Once you've used it to clear that hurdle, there's no ongoing maintenance requirement - the exam itself just documents where your foundational nursing-process knowledge stood at that point in time.
This also means comparing "difficulty" or "pass rates" across different NACE I-named credentials is misleading; the standards, formats, and even the administering bodies can differ completely. If you came across broader terminology questions, What Is NACE I?, What Is A NACE I?, and What Does NACE I Mean? all address naming and identity directly, while NACE I Certification, What Is NACE I Certification?, and NACE I Training go deeper on structure and preparation resources.
Key Takeaway
NACE-FON's value is entirely contextual - it matters because your target nursing program says it matters. Confirm exactly how your school uses the score before you build a study plan or budget for retesting.
