What Is A NM-EE98, Exactly?
NM-EE98 refers to the New Mexico EE-98 Electrical Contractor Exam, specifically Part 1: Commercial and Industrial. It's one of three trade-knowledge exams that make up the full EE-98 Residential and Commercial Electrical contractor classification issued by the New Mexico Regulation and Licensing Department, Construction Industries Division (CID). Part 1 is not a standalone license - it's the commercial and industrial knowledge test that, combined with Part 2 (Residential) and Part 3 (Specialties), demonstrates the trade competency a qualifying party needs before CID will attach a contractor's license to their name.
If you've searched "what is a NM-EE98" and landed here expecting a single all-purpose credential, it helps to reset expectations: this is a segmented exam system, and Part 1 is the segment focused specifically on commercial and industrial electrical work - services, equipment, and installation practices you'd encounter on job sites larger and more complex than a typical residence.
Who Issues It and Who Administers the Test
The credential sits under the authority of the New Mexico Regulation and Licensing Department's Construction Industries Division. CID sets the licensing rules, reviews qualifying-party applications, and issues certificates. The actual test delivery - scheduling, proctoring, scoring - is handled by PSI, a third-party testing provider used across many state licensing programs.
This distinction matters because your paperwork (qualifying-party application, experience affidavits) goes through CID, while your test-day logistics (booking a seat, calculator rules, reference material policy) come from PSI's exam bulletin. Confusing the two is a common source of frustration for first-time applicants. For a full breakdown of who needs to file what and when, see NM-EE98 Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Exam Format: Questions, Time, and Passing Score
Per the PSI bulletin revised April 3, 2026, Part 1 is structured as follows:
- 80 questions, computer-administered, multiple choice
- 200 minutes allotted
- 75% passing requirement - you need 60 correct answers
- Open book format with approved bound references
- A silent, nonprinting, nonprogrammable calculator is permitted
For comparison, Part 2 (Residential) is 40 questions in 100 minutes, and Part 3 (Specialties) is 50 questions in 135 minutes. Part 1 is the longest and most heavily weighted of the three trade exams, reflecting the breadth of commercial and industrial electrical topics it covers.
| Exam Part | Questions | Time Allotted | Focus Area |
|---|---|---|---|
| Part 1 | 80 | 200 minutes | Commercial and Industrial |
| Part 2 | 40 | 100 minutes | Residential |
| Part 3 | 50 | 135 minutes | Specialties |
Because passing requires 60 of 80 correct rather than a simple majority, margin for error is tight. A closer look at exactly how that score is calculated and what it means for guessing strategy is covered in NM-EE98 Passing Score 2026: Exactly What You Need to Pass.
Key Takeaway
You have roughly 2.5 minutes per question on Part 1. That's generous compared to some licensing exams, but only if you're not stopping to hunt through unfamiliar code sections - know your reference material's structure before test day.
The 10 Domains Tested on Part 1
PSI's bulletin allocates specific question counts across ten content domains. These allocations are official, not estimates, which makes them one of the most useful planning tools available to a candidate.
Domain 1: General Knowledge and Electrical Installation Requirements (13 questions)
The largest single domain on Part 1. Covers foundational installation rules, definitions, and general requirements that apply across commercial and industrial work.
- Highest point value on the exam - prioritize accordingly
Domain 2: Services, Feeders, and Branch Circuits (10 questions)
Sizing, calculations, and requirements for how power gets from the utility connection into a building and out to loads.
Domain 3: Overcurrent Protection (5 questions)
Breaker and fuse selection, coordination, and protection requirements for equipment and conductors.
Domain 4: Grounding and Bonding (10 questions)
Grounding electrode systems, bonding requirements, and the differences that matter in commercial versus industrial applications.
Domain 5: Conductors and Cables (8 questions)
Ampacity, insulation types, and selection criteria for various conductor and cable applications.
Domain 6: Raceways and Boxes (8 questions)
Sizing and fill calculations, support requirements, and box selection for commercial and industrial installations.
Domain 7: Hazardous Locations, Special Occupancies, and Special Equipment (10 questions)
The second-largest domain. Classified locations, special occupancy rules, and equipment requirements unique to industrial settings.
Domain 8: Lighting, Signs, and General-Use Equipment (6 questions)
Installation and circuiting requirements for lighting systems, signage, and general-use equipment.
Domain 9: Motors, Transformers, and Generators (6 questions)
Sizing, protection, and installation rules specific to rotating equipment and transformers found in commercial/industrial settings.
Domain 10: New Mexico State Code (4 questions)
State-specific amendments and requirements layered on top of the national code base.
Notice that Domains 1, 2, 4, and 7 together account for 43 of the 80 questions - well over half the exam. A domain-by-domain breakdown with more detail on subtopics and typical question phrasing is available in NM-EE98 Exam Domains 2026: Complete Guide to All 10 Content Areas.
What You Can Bring Into the Testing Room
Part 1 is open book, but "open book" comes with strict conditions. Approved references include:
- The 2020 NEC or NEC Handbook
- The 2020 New Mexico Electrical Code
- The 2007 National Electrical Safety Code
All references must be bound. Highlighting, underlining, and permanent tabs are allowed. Handwritten notes, loose papers, and temporary tabs are not permitted and can be flagged during check-in. This is a detail candidates frequently underestimate - showing up with sticky notes or a printed cheat sheet can create problems before you even sit down.
How Part 1 Fits Into the Full EE-98 Classification
Passing Part 1 is necessary but not sufficient for full trade qualification under the EE-98 classification. Unless CID approves an exemption, a qualifying party also needs to pass Part 2 (Residential) and Part 3 (Specialties). Separately, a Business and Law examination - or an approved course in lieu of it - is required regardless of trade-exam results.
A CID-approved NASCLA waiver can remove the trade-exam requirement, but it does not touch the experience or Business and Law requirements - those still apply in full. This is a distinction worth understanding before assuming a NASCLA credential shortcuts the whole process.
This structure is why a search for "what is a NM-EE98" doesn't have a one-line answer - it's genuinely a piece of a larger licensing puzzle. For the full picture of how all the pieces connect, see NM-EE98 Certification and What Is NM-EE98 Certification?.
Who Actually Needs This Exam
Part 1 is relevant to anyone pursuing qualifying-party status for the EE-98 classification who plans to take on commercial or industrial electrical contracting work in New Mexico. This typically includes:
- Electricians moving into a contractor role who will serve as the qualifying party on a license
- Business owners bringing electrical work in-house who need a licensed qualifying party attached to the company
- Established residential contractors expanding into commercial and industrial scopes
Qualifying-party applicants must document four years (8,000 hours) of relevant experience, submit a notarized application with experience affidavits, and receive CID approval before they're eligible to test. That approval is valid for six months, so timing your application and your exam date matters - approval can lapse if you wait too long. For a walkthrough of eligible experience and documentation, see NM-EE98 Requirements 2026: Eligibility, Prerequisites & How to Qualify. Once you pass, scores remain valid for one year, which affects how you sequence Parts 1, 2, and 3.
Cost and Timeline Basics
The initial three-part trade-exam fee (covering Parts 1, 2, and 3 together) is $269.06. If you fail a specific part and need to retake it, the retake fee is $89.69 per part - so a Part 1 retake alone costs that amount, not the full three-part fee again. The separate Business and Law examination costs $68.88. The qualifying-party application itself costs $30, plus a $6 certificate fee per classification.
Once licensed, contractor licenses renew every three years, requiring the qualifying party's signature and bond coverage for the renewal term. A qualifying-party certificate stays valid only while it's attached to an active license; if it sits unattached for two consecutive years, it gets canceled. A complete fee table covering every stage - application, testing, retakes, and renewal - is broken down in NM-EE98 Certification Cost 2026: Complete Pricing Breakdown.
Key Takeaway
Failing Part 1 doesn't reset your progress on Parts 2 and 3 - you only pay the $89.69 retake fee for the specific part you didn't pass, provided you're within your approval and score-validity windows.
Preparing for Part 1 Without Wasting Time
Given that this is an open-book exam with fixed domain weights, preparation should be less about memorizing raw numbers and more about knowing exactly where information lives in your bound references and how quickly you can retrieve it under time pressure. A practical approach:
Heavy Domains First
- Work through Domain 1 (General Knowledge and Electrical Installation Requirements) and Domain 2 (Services, Feeders, and Branch Circuits) - together worth 23 of 80 questions
- Build and test your reference tabbing system on these sections
Grounding and Special Occupancies
- Focus on Domain 4 (Grounding and Bonding) and Domain 7 (Hazardous Locations, Special Occupancies, and Special Equipment) - another 20 questions combined
- Run timed practice sets to simulate the 200-minute window
Remaining Domains and Full Simulation
- Cover Domains 3, 5, 6, 8, 9, and 10 in remaining study blocks
- Take at least one full-length timed practice exam using only permitted reference materials
A more detailed week-by-week plan, including how to weight review sessions against the exact domain question counts, is laid out in NM-EE98 Study Guide 2026: How to Pass on Your First Attempt. If you're still gauging how much effort this exam actually demands relative to your current experience level, How Hard Is the NM-EE98 Exam? Complete Difficulty Guide 2026 walks through that in more depth, and NM-EE98 Pass Rate 2026: What the Data Shows looks at what's publicly known about outcomes.
Running realistic, timed practice questions on our NM-EE98 practice test platform is one of the most direct ways to test whether your reference-tabbing system and pacing actually hold up under exam conditions, rather than just in casual review.
