The NJ-EC Passing Score, Explained
If you're preparing for the New Jersey Electrical Contractor License Exam, the number that matters most is 70%. That's the passing score PSI Services LLC applies across every component the New Jersey Board of Examiners of Electrical Contractors requires: the trade exam, Business and Law, and Alarm Systems Electrical Contractor. There is no curve, no scaled scoring, and no partial credit for "close enough" answers. You either answer at least 70% of the scored questions correctly, or you don't.
This article breaks down exactly what that 70% means for each component, how the question counts and time limits interact with your pacing, and what happens if you fall short. For a broader look at how the exam is structured, see the NJ-EC Exam Domains 2026: Complete Guide to All 12 Content Areas.
Three Exams, Three Separate Scores
A common misconception is that the NJ-EC is a single test with one composite score. It isn't. First-time candidates sit for three distinct, separately scored examinations, typically on the same testing day at a PSI center in New Jersey:
- Trade examination - 100 questions, 255 minutes, 70 correct required
- Business and Law - 50 questions, 130 minutes, 35 correct required
- Alarm Systems Electrical Contractor - 50 questions, 165 minutes, 35 correct required
That totals 200 listed questions and 550 testing minutes across three separate components. Passing one doesn't offset a failure on another - each must independently hit 70%. This matters for how you allocate study time; treating the trade exam as "the real test" and cramming Business and Law the night before is a common mistake covered in more depth in the NJ-EC Study Guide 2026: How to Pass on Your First Attempt.
| Component | Questions | Time Limit | Passing Score |
|---|---|---|---|
| Trade Exam | 100 | 255 minutes | 70 correct (70%) |
| Business and Law | 50 | 130 minutes | 35 correct (70%) |
| Alarm Systems Electrical Contractor | 50 | 165 minutes | 35 correct (70%) |
Trade Exam: 100 Questions, 255 Minutes
The trade examination is the largest and most technically demanding of the three components. It's computer-based and open-book, but "open-book" comes with strict conditions: PSI supplies the 2023 National Electrical Code at the testing center, and it is the only permitted trade reference. You cannot bring your own NEC copy, and you cannot mark, highlight, or index the book PSI provides. An on-screen calculator is built into the testing software, so you don't need to bring one.
With 255 minutes for 100 questions, you have roughly 2.5 minutes per question on average - generous by exam standards, but that time gets consumed quickly if you're flipping through an unfamiliar Code book looking for tables you haven't practiced locating. Comfort navigating the 2023 NEC under time pressure is arguably as important as knowing the material itself.
Key Takeaway
Because the trade exam allows an unmarked, PSI-supplied NEC only, practice locating Article references and tables quickly during your prep - don't rely on tabs or highlights you'll use on test day, because you won't have them.
Why Grounding and Bonding Deserves Extra Attention
The trade exam's 100 questions are drawn from PSI's published outline across twelve content domains: General Electrical Knowledge, Raceways and Enclosures, Services Feeders and Branch Circuits, Overcurrent Protection, Conductors and Cables, Grounding and Bonding, Equipment for General Use, Special Occupancies, Special Equipment and Conditions, Motors and Controls, Low Voltage and Communications Circuits, and Safety.
Of these, Grounding and Bonding is the largest single domain on the outline. Since your passing score depends on total correct answers across all 100 questions, a domain with more questions has proportionally more influence on whether you clear the 70-question threshold. Underestimating Grounding and Bonding is one of the more common reasons candidates fall just short of passing.
Grounding and Bonding
Candidates must understand how grounding electrode systems, bonding jumpers, and equipment grounding conductors work together to provide a low-impedance fault path, along with sizing methods drawn from the 2023 NEC.
- Grounding electrode conductor sizing and connection methods
- Bonding of service equipment, metal water piping, and structural metal
- Equipment grounding conductor sizing versus overcurrent device rating
- Separately derived systems and their grounding requirements

And if you're still weighing how demanding this exam is relative to your background, the How Hard Is the NJ-EC Exam? Complete Difficulty Guide 2026 article walks through that in more detail.
Open-Book Rules That Affect Your Score
Reference material rules differ across the three components, and misunderstanding them can quietly cost you points:
- Trade exam: PSI supplies the 2023 NEC only. No personal copies. No markings or indexing on the supplied book.
- Business and Law: Uses the candidate's NASCLA New Jersey guide, second edition.
- Alarm Systems: PSI supplies the 2023 NEC, but candidates bring their own approved references - NFPA 72 (2022), the listed 2025 NTC manuals, and CCTV from Light to Pixels, third edition (2014).
For candidate-owned references (Business and Law and Alarm Systems), you're permitted to highlight, underline, and permanently tab the material before test day, but the Board must approve the reference, and you cannot add loose papers, temporary tabs, or write anything during the exam itself. Show up with unapproved or improperly marked references and you risk not being able to use them at all - effectively taking that component closed-book.
What Happens If You Miss the Passing Score
Falling short of 70% on any component doesn't end your path to licensure, but it does trigger specific rules you need to plan around:
- PSI allows three total attempts to pass all three components.
- After a failed first or second attempt, there's a six-month wait before retesting that component.
- If you haven't passed all three components within five years, you must reapply to the Board.
- Your first examination attempt must occur within two years of establishing eligibility.
The six-month wait is the detail that catches most people off guard. It's not a scheduling inconvenience you can shorten by paying an extra fee - it's a mandatory cooling-off period. That makes your first attempt disproportionately important: passing all three components in one sitting avoids months of delay. For a full picture of who qualifies to test in the first place, review NJ-EC Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Key Takeaway
Because a failed attempt costs you six months, treat your first test date as the one that counts - don't schedule "just to see where you stand."
Scheduling Study Time Around the 70% Target
A 70% passing threshold across three components with very different question counts calls for a study calendar that respects proportions - spend more time where more points are available, and don't neglect the smaller components just because they look easier on paper.
Trade Exam Core Domains
- Grounding and Bonding, Services Feeders and Branch Circuits, and Overcurrent Protection - the domains most likely to carry heavier question counts
- Practice locating NEC tables without personal tabs, since the exam-day book will be unmarked
Remaining Trade Domains
- Raceways and Enclosures, Conductors and Cables, Equipment for General Use, Special Occupancies, Special Equipment and Conditions, Motors and Controls, Low Voltage and Communications Circuits, Safety, and General Electrical Knowledge
Business and Law
- Work through the NASCLA New Jersey guide, second edition, and finalize any permanent tabbing before test day
Alarm Systems
- Review NFPA 72 (2022), the 2025 NTC manuals, and CCTV from Light to Pixels - confirm all references are Board-approved and properly tabbed
This isn't a generic weekly template - it's built around the reality that the trade exam has double the questions and time of either of the other two components, so it earns roughly double the calendar weeks. For a deeper walkthrough of first-attempt strategy, see the NJ-EC Study Guide 2026: How to Pass on Your First Attempt, and for practice questions organized by domain, our practice test platform mirrors the same 100-question trade format you'll see on exam day.
How the Passing Score Fits Into Total Cost
Every attempt at these exams carries a cost, which is one more reason the 70% threshold deserves respect rather than a "we'll see" mindset. PSI examination fees run $84 for the trade exam, $47 for Business and Law, and $49 for Alarm Systems - $180 total for a first attempt at all three. That's separate from the $100 Board application fee and the initial contractor license fee, which is tiered at $225, $150, or $75 depending on whether you're applying in the first, second, or third year of the triennial cycle.
Failing a component means paying to retest it after the mandatory wait - an avoidable expense if your prep is thorough the first time. For the complete fee breakdown across application, testing, and licensing, see NJ-EC Certification Cost 2026: Complete Pricing Breakdown.

FAQ
Yes. The trade exam, Business and Law, and Alarm Systems Electrical Contractor each require 70% correct - 70 of 100 questions on the trade exam and 35 of 50 questions on each of the other two.
No. PSI supplies the 2023 National Electrical Code at the test center, and it is the only permitted trade reference. Personal copies and any marking or indexing of the supplied book are prohibited.
You retest only the failed component after a required six-month wait following a first or second failed attempt. You have up to three total attempts, and all three components must be passed within five years of establishing eligibility.
The trade exam allows 255 minutes for 100 questions, which averages to roughly 2.5 minutes per question, though actual pacing will vary depending on how much time you spend navigating the NEC.
Grounding and Bonding is the largest domain on PSI's published 100-item trade outline, so it carries more weight toward your 70-question passing threshold than smaller domains and should be a top study priority.
