- Part 1 covers 80 questions in 200 minutes, and you need 60 correct (75%) to pass.
- Domain 1, General Knowledge and Electrical Installation Requirements, carries 13 questions - the heaviest single domain.
- Only bound copies of the 2020 NEC, 2020 New Mexico Electrical Code, and 2007 NESC are allowed; no loose papers or handwritten notes.
- A qualifying-party approval is valid six months and a passing score stays valid one year, so training and scheduling must line up.
What "NM-EE98 Training" Actually Means
Training for NM-EE98 Part 1 isn't generic electrical-code review - it's preparation for a specific PSI-administered exam tied to New Mexico's Construction Industries Division (CID) contractor licensing system. The exam you're training for is Part 1, Commercial and Industrial, of the EE-98 Residential and Commercial Electrical classification. That distinction matters because CID also requires Part 2 (Residential) and Part 3 (Specialties) before a candidate holds the full trade qualification, unless CID grants an exemption.
Effective training for Part 1 means building fluency across ten defined domains, learning the exact reference materials PSI allows you to bring into the testing center, and pacing yourself against a firm 200-minute clock. If you haven't yet mapped out what each domain actually tests, the NM-EE98 Exam Domains 2026: Complete Guide to All 10 Content Areas is a useful companion to this training plan, and the NM-EE98 Study Guide 2026: How to Pass on Your First Attempt lays out a broader first-attempt strategy.
Exam Format and Registration Mechanics You Must Train Around
Per the PSI bulletin revised April 3, 2026, Part 1 consists of 80 questions delivered in 200 minutes, with a 75% passing requirement - 60 correct answers. That works out to roughly 2.5 minutes per question, which is generous for an open-book format as long as you aren't flipping through unmarked code books hunting for sections you've never reviewed.
Registration and cost details matter for training planning too. The initial three-part trade-exam fee is $269.06, and if you fail a part, the retake fee is $89.69 per part. Business and Law is tested separately for $68.88. Because retakes cost money and require rescheduling, training time invested before your first attempt at Part 1 pays off directly. For a full cost breakdown across every stage of licensing, see NM-EE98 Certification Cost 2026: Complete Pricing Breakdown.
Two administrative details should shape your training calendar:
- Qualifying-party approval lasts six months. If your application approval expires before you test, you lose scheduling time you spent training toward.
- Passing scores remain valid for one year. If you pass Part 1 but haven't yet trained for Parts 2 and 3, don't let that window lapse.
If you're still confirming eligibility before you even start training, check NM-EE98 Requirements 2026: Eligibility, Prerequisites & How to Qualify first - training is wasted effort if the application piece isn't lined up.
Key Takeaway
Build your training schedule backward from your six-month qualifying-party approval window, not forward from an arbitrary study start date.
Domain-by-Domain Training Priorities
Part 1's question allocation across its ten domains is fixed by the bulletin: 13, 10, 5, 10, 8, 8, 10, 6, 6, and 4 questions respectively. That distribution should directly drive how much training time each topic gets. Domain 1 is the largest single block on the exam, so it deserves the largest training investment.
Domain 1: General Knowledge and Electrical Installation Requirements (13 questions)
The largest domain on Part 1. Training here should cover general NEC organization, definitions, and baseline installation rules that other domains build on.
- Practice locating definitions and general requirements quickly in your bound NEC or NEC Handbook
Domain 2: Services, Feeders, and Branch Circuits (10 questions)
Tied for second-largest weight. Focus training on load calculations, sizing rules, and how services and feeders interact with branch-circuit requirements in commercial and industrial settings.
- Work practice problems involving demand factors and conductor sizing
Domain 7: Hazardous Locations, Special Occupancies, and Special Equipment (10 questions)
Equally weighted with Domains 2 and 4. Commercial and industrial work frequently touches classified locations, so training should include tabbed navigation to these NEC articles.
- Know which classification tables apply to which occupancy types
Domain 4: Grounding and Bonding (10 questions)
A heavily weighted, detail-dense domain. Training should emphasize sizing grounding electrode conductors and bonding jumpers correctly under commercial-scale scenarios.
- Drill the difference between grounding and bonding terminology and application
The remaining domains - Overcurrent Protection (5), Conductors and Cables (8), Raceways and Boxes (8), Lighting, Signs, and General-Use Equipment (6), Motors, Transformers, and Generators (6), and New Mexico State Code (4) - carry lighter but still meaningful weight. Domain 10, New Mexico State Code, is smaller in question count but tests state-specific amendments that generic national code training won't cover, so don't skip it just because it's the lightest domain. A full breakdown of every domain's scope is in the NM-EE98 Exam Domains 2026: Complete Guide to All 10 Content Areas.

Complete Difficulty Guide 2026 walks through that comparison, and NM-EE98 Passing Score 2026: Exactly What You Need to Pass explains exactly how the 60-of-80 threshold is applied.
Training With Your Approved References
Because Part 1 is open book, part of effective training is learning to use your references as fast-retrieval tools rather than reading material. The approved references are the 2020 NEC or NEC Handbook, the 2020 New Mexico Electrical Code, and the 2007 National Electrical Safety Code. All must be bound.
PSI's rules on markup are specific, and training should respect them exactly:
- Permitted: highlighting, underlining, and permanent tabs
- Prohibited: handwritten notes, loose papers, and temporary tabs
Practice tabbing your code books during training exactly as you plan to bring them into the exam. If your tab system isn't built and tested before exam day, you're training with a different tool than the one you'll actually use under a 200-minute clock.
A Domain-Based Training Timeline
General study methods - spaced repetition, timed drills, regular review sessions - only matter if they're pointed at the right material at the right time. Because Domains 1, 2, 4, and 7 together account for 43 of the 80 questions, a training schedule should front-load them.
Domain 1 and Domain 2
- Review general installation requirements, then move into services, feeders, and branch-circuit sizing
- Set up permanent tabs in your NEC for both domains
Domain 4 and Domain 7
- Drill grounding/bonding sizing tables
- Map hazardous location classifications to specific NEC articles
Domains 3, 5, 6, 8, 9
- Cover overcurrent protection, conductors, raceways, lighting/signs, and motors/transformers/generators
- Time yourself at roughly 2.5 minutes per practice question
Domain 10 and Full Review
- Study New Mexico state-specific code amendments
- Run full-length timed practice sessions using only bound, tabbed references

Who Hires for This Credential
Passing Part 1 and completing the full EE-98 pathway supports New Mexico contractor licensure through CID, which is what allows an individual to serve as the qualifying party on an electrical contracting license. This matters to commercial and industrial employers, general contractors bidding on state and municipal projects, and firms that need a licensed qualifying party attached to their contractor license to bid and operate legally in New Mexico.
Because a qualifying-party certificate is canceled after two consecutive years unattached to an active license, employers value candidates who can step directly into that role. If you're weighing whether the credential translates into better job opportunities or pay, NM-EE98 Jobs and NM-EE98 Salary Guide 2026: Complete Earnings Analysis go deeper into that side of the picture, and Is the NM-EE98 Certification Worth It? Complete ROI Analysis 2026 weighs the licensing investment against the career outcome.
Training Beyond Part 1: The Full Trade Qualification
Part 1 training doesn't complete the EE-98 trade qualification on its own. CID requires Part 2 (Residential, 40 questions in 100 minutes) and Part 3 (Specialties, 50 questions in 135 minutes) unless an exemption is approved, plus a separate Business and Law exam satisfied by examination or an approved course. A NASCLA waiver, if CID-approved, removes only the trade-exam requirement - experience and Business and Law obligations still apply.
| Exam Segment | Questions | Time |
|---|---|---|
| Part 1 - Commercial and Industrial | 80 | 200 minutes |
| Part 2 - Residential | 40 | 100 minutes |
| Part 3 - Specialties | 50 | 135 minutes |
Qualifying-party applicants also need four years (8,000 hours) of relevant experience, plus a notarized application and experience affidavits, before CID approval to test. The application costs $30 plus a $6 certificate fee per classification. Contractor licenses then renew every three years, requiring the qualifying-party signature and bond coverage for the renewal term.
Training for Part 1 in isolation is a smart starting point, but plan your calendar with these downstream steps in mind so your six-month approval window and one-year score validity don't work against you. You can build and check your progress against timed, domain-weighted practice questions on our main practice test platform as you move through each stage.
Key Takeaway
Treat Part 1 training as the first phase of a multi-part licensing process, not a standalone finish line.
