What Is NACE I, Exactly?
NACE I stands for the Nursing Acceleration Challenge Examination: Foundations of Nursing (NACE-FON). It is not a professional license or a renewable certification - it's an educational assessment built for licensed practical/vocational nurses (LPN/LVNs) who are applying to, or already enrolled in, accredited professional nursing programs. If you've landed here searching for general definitions, our companion pages on What Is NACE I?, NACE I Meaning, and What Does NACE I Stand For? cover the naming and terminology in more depth. This article focuses on what the exam actually measures, how it's structured, and what it costs to take.
Because "NACE I" is used by more than one organization across different fields, it's worth being precise: everything on this page describes the National League for Nursing's Foundations of Nursing exam specifically, not any other credential that happens to share the acronym.
Who Develops and Administers NACE I
The National League for Nursing (NLN) develops and maintains NACE-FON. The current official version, 1.2, was documented in 2023 and remains the active form of the exam. The NLN doesn't just write the content - it also controls the testing infrastructure. Exams are delivered on the NLN Assess platform, branded as Assess.ai, which supports two delivery paths:
- Campus exams, where faculty at the nursing program administer the test on-site.
- Virtual exams, proctored one-on-one through Proctor360, the NLN's remote proctoring partner.
This dual-delivery model matters for planning purposes: your school decides which option it offers (or whether it offers both), and that choice affects price, scheduling flexibility, and what you're allowed to have at your workstation. For a breakdown of exact testing windows and how scheduling typically works across programs, see NACE I Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Exam Format, Timing, and Platform
NACE-FON Version 1.2 consists of 100 scored content items, and candidates are given a 150-minute limit to complete them - that averages out to roughly a minute and a half per item, though the exam isn't strictly timed per question. There's no essay or clinical simulation component; it's a scored, item-based assessment focused on nursing-process reasoning at the foundational level.
If you're taking the virtual version through Proctor360, the materials rules are strict and specific. Only the following are permitted at your workstation:
- A basic four-function calculator
- A dry-erase board no larger than 8.5 by 11 inches
- A dry-erase marker
- An eraser
No scratch paper, no phone, no secondary monitor, and no reference materials. Campus-administered exams may follow slightly different in-room protocols set by your faculty proctor, so confirm the specifics with your program before test day.
Key Takeaway
If you're testing virtually, practice working problems on a small dry-erase board beforehand - you won't have scratch paper, and getting used to a compact surface changes how you organize dosage-calculation work.
The Four Nursing-Process Domains
NACE-FON organizes its 100 items around the nursing process, split into four domains with distinct weightings. Understanding these weights is the single most useful thing you can do before you start studying, because it tells you where your time delivers the most return.
Domain 1: Assessment (24%)
Covers data collection, recognizing normal versus abnormal findings, and prioritizing what information matters first in a patient scenario.
- Distinguishing subjective vs. objective data
- Recognizing cues that require immediate follow-up
Domain 2: Evaluation (23%)
Tests your ability to judge whether a nursing intervention or care plan achieved its intended outcome.
- Comparing patient response against expected outcomes
- Determining when a plan needs revision
Domain 3: Implementation (29%)
The largest domain on the exam, focused on carrying out nursing actions safely and correctly.
- Sequencing and prioritizing interventions
- Applying foundational skills within scope of practice
Domain 4: Planning (24%)
Covers goal-setting and organizing the care plan around assessment data.
- Writing measurable, patient-centered goals
- Aligning planned interventions with identified priorities
Because Implementation carries the heaviest weight at 29%, it deserves proportionally more of your review time - but not at the expense of the other three, which together still make up over 70% of the exam. For a full item-by-item walkthrough of what each domain actually tests, read NACE I Exam Domains 2026: Complete Guide to All 4 Content Areas.
| Domain | Weight | Core Focus |
|---|---|---|
| Assessment | 24% | Data collection and cue recognition |
| Evaluation | 23% | Judging outcomes against goals |
| Implementation | 29% | Executing nursing actions correctly |
| Planning | 24% | Setting goals and organizing care |
How Scoring Works (and Why There's No National Cutoff)
This is one of the most misunderstood parts of NACE-FON: the NLN does not set a national passing score. Instead, your results come back as a Coaching Report showing percentage-correct for the overall exam and for each of the four domains individually. Your nursing program then applies its own standard - for admission, placement, or course credit - based on that report.
Practically, this means two students could take the identical exam and be evaluated completely differently depending on which program they're applying to. If you're unsure what score your target program requires, that information comes from the school, not from the NLN. We break down how to interpret your Coaching Report and what "good enough" typically looks like in NACE I Passing Score 2026: Exactly What You Need to Pass.
Cost, Registration, and Retake Rules
Effective March 1, 2026, NACE-FON pricing is structured around delivery method:
- $75 for a school-paid campus exam
- $96 for a virtual exam through Proctor360
- $62 for the official Foundations prep product
The NLN itself does not cap how many times you can attempt the exam, but individual institutions may set their own limits - so a lack of an NLN-imposed cap doesn't mean unlimited retakes at your school. There is a required 30-day waiting period between attempts unless your program has communicated a different frequency to you directly. Every score you earn gets reported, and the NLN retains those scores for three years, so a weak early attempt doesn't simply disappear from the record.
For a complete accounting of what you might spend across prep materials, retakes, and delivery-method choices, see NACE I Certification Cost 2026: Complete Pricing Breakdown.
Key Takeaway
Since all attempts are reported and retained for three years, treat your first sitting as the one that matters - budget prep time accordingly rather than planning on a "practice run."
Who Takes NACE I and Why
NACE-FON is aimed specifically at LPN/LVNs pursuing entry into, or already progressing through, accredited professional nursing programs - most commonly bridge or advanced-placement pathways toward RN licensure. Programs use the Coaching Report to gauge whether an applicant's foundational nursing-process knowledge is strong enough to succeed at the next level, or to place already-admitted students appropriately within a curriculum.

Preparing for the Four Domains
Effective NACE-FON prep is less about generic test-taking tricks and more about matching study time to domain weight and question style. Since Implementation carries the most weight (29%), and Assessment and Planning are close behind at 24% each, a simple even split across four weeks is a reasonable starting structure - just tilt slightly more time toward Implementation and treat Evaluation, the lightest domain at 23%, as the anchor you review last to reinforce everything else.
Assessment (24%)
- Drill subjective vs. objective data recognition
- Practice identifying priority cues in scenario-based items
Planning (24%)
- Practice writing measurable, patient-centered goals
- Link planning items back to Week 1 assessment data
Implementation (29%)
- Extra time here given the heaviest domain weight
- Focus on prioritization and sequencing of interventions
Evaluation (23%) + Full Review
- Practice judging outcomes against expected goals
- Run full-length timed practice under the 150-minute limit
Because the exam is delivered digitally on Assess.ai, practicing under similar timed, on-screen conditions matters more than it would for a paper test - you want the 150-minute pacing to feel automatic before test day.

Frequently Asked Questions
No. NACE-FON is an educational assessment, not a renewable certification. There's no CEU requirement and no renewal cycle - you take it as part of an admission or placement process, and the result feeds into your program's decision.
There isn't a single national passing score. The NLN reports percentage-correct results overall and by domain through a Coaching Report, and each nursing program sets its own standard for what counts as acceptable. Check with your specific program for its cutoff.
The NLN itself does not cap attempts, but your institution may set its own limit. Regardless of caps, you must wait at least 30 days between attempts unless your school communicates a different frequency, and every score is reported and retained for three years.
Only 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 other materials are permitted during Proctor360-monitored virtual sessions.
Effective March 1, 2026, a school-paid campus exam is $75, a virtual exam is $96, and the official Foundations prep product is $62. Costs beyond these may depend on your institution's own fee structure.
