NM-GB98 Meaning

What Does NM-GB98 Actually Mean?

"NM-GB98" refers to a specific credential category under the New Mexico contractor licensing system: the General Building Contractor Part 2 examination, administered as part of a required combination test alongside the Residential Building Contractor Part 1 exam (often labeled GB-2). Together, GB-2 and GB-98 make up the technical testing requirement for anyone seeking a General Building license classification in New Mexico. If you're piecing together the acronym for the first time, our companion post on What Does NM-GB98 Stand For? breaks down the letters and numbers in more detail, and What Is NM-GB98? covers the broader licensing context.

It's worth being precise here because the "GB-98" label can be confusing if you've seen similar-looking acronyms attached to unrelated credentialing programs elsewhere. In New Mexico, GB-98 is not a standalone certificate you can earn by itself - it is one half of a mandatory two-part technical exam pairing, and passing it (along with GB-2 and a separate Business and Law requirement) is what unlocks a General Building contractor license.

Who Regulates the NM-GB98 and How the Test Is Delivered

The exam falls under the authority of the New Mexico Regulation and Licensing Department, Construction Industries Division, which approves the examination content. Actual test delivery happens through computer-based testing administered by PSI, a widely used licensing exam vendor. Candidates should reference the current PSI contractor candidate bulletin - the version relevant to this exam cycle was updated April 3, 2026 - for the most current scheduling, ID, and testing-center policies.

Because the Construction Industries Division sets the rules and PSI simply administers the computer-based sessions, any procedural questions about testing centers, ID requirements, or appointment rescheduling should be directed through PSI's contractor bulletin channel rather than assumed from generic testing advice you might find elsewhere.

Inside the Two-Part Combination Exam

The GB-98 combination technical exam is really two exams bundled into a single licensing requirement:

• GB-2 Residential Building Contractor Part 1: 80 questions, 225 minutes
• GB-98 General Building Contractor Part 2: 100 questions, 310 minutes

The full combination costs $269.06. If you pass one part but not the other, you don't have to pay for the entire combination again - a one-part retake costs $134.53. Both technical parts are open book and each requires a 75% score to pass.

That open-book format changes how you should prepare. It's less about pure memorization and more about knowing exactly where information lives in your approved references and how quickly you can locate it under time pressure - 225 minutes for 80 questions on Part 1, and 310 minutes for 100 questions on Part 2.

What the 17 Domains Actually Cover

The combination exam is broken into 17 distinct content domains split across the two parts. Understanding the weighting helps you decide where to spend your study hours. A full breakdown of every domain lives in NM-GB98 Exam Domains 2026: Complete Guide to All 17 Content Areas, but here's the shape of it:

Notice that General Code, Plan Reading, and Estimating carries the heaviest weight in Part 2 at 27 questions - nearly a quarter of the entire exam. Concrete and Concrete Reinforcement (15 questions) and Metals (10 questions) are also disproportionately important on Part 2 compared to Part 1. If you're building a study schedule, these numbers should directly influence your time allocation rather than treating all 17 domains equally.

Eligibility: The Experience and Business/Law Layer

Before you can even schedule the GB-2/GB-98 combination, you need to meet New Mexico's experience threshold: four years and 8,000 hours of qualifying experience within the preceding 10 years. Approved education or training can offset part of this - candidates may receive half-time credit for up to one-half of the total requirement, meaning classroom or program hours can substitute for a portion, but not all, of the fieldwork clock.

New contractor candidates also have to clear a separate hurdle: Business and Law. This is satisfied either by passing the PSI Business and Law examination or by completing an approved course. The PSI version costs $68.88, contains 50 questions, allows 130 minutes, is open book, and also requires a 75% passing score - the same threshold as the technical exams.

Once you're deemed eligible to test, that eligibility window lasts six months, and once you pass, your scores remain valid for one year while you complete the licensing application process. There's also a qualifying-party application and work-affidavit fee of $36 tied to demonstrating your experience. For the full eligibility checklist, see NM-GB98 Requirements 2026: Eligibility, Prerequisites & How to Qualify.

The Fee Structure Behind the Name

Because the GB-98 label gets confused with other similarly-numbered credentials online, it's worth being explicit about what candidates in New Mexico actually pay:

• Combination technical exam (GB-2 + GB-98): $269.06
• One-part retake: $134.53
• Business and Law exam (PSI): $68.88
• Qualifying-party application and work-affidavit fee: $36

None of these fees include continuing education costs after licensure, because General Building renewal in New Mexico has no continuing education requirement - a detail that surprises many candidates coming from states with mandatory CE hours.

Open-Book References and What "General Building" Really Tests

Both technical exam parts are open book, but "open book" comes with rules. Approved references include the listed 2021 New Mexico building codes, the 2021 IRC or IBC as applicable, and various trade texts. Your references must be bound and may be highlighted, underlined, indexed, and permanently tabbed before you walk into the test - but they cannot contain handwritten notes or loose inserted papers. A silent, nonprinting, nonprogrammable calculator is allowed alongside your references.

This structure means the exam isn't really testing whether you can recall code section numbers from memory. It's testing whether you understand the underlying logic of sitework, concrete reinforcement, masonry, carpentry, metals, roofing, associated trades, general code and plan reading, estimating, and OSHA safety well enough to navigate your references quickly and apply them correctly to scenario-based questions. Tabbing your references intelligently before test day, organized around the domain weights above, is arguably as important as raw content knowledge.

Mapping Study Time to the NM-GB98 Timeline

Given the six-month eligibility window and the domain weighting above, a practical approach is to sequence your study by question density rather than by the order domains happen to be listed. Spend early weeks on the heaviest-weighted areas - General Code, Plan Reading, and Estimating (27 questions on Part 2, 14 on Part 1) and Concrete and Concrete Reinforcement (15 questions on Part 2, 9 on Part 1) - since mastery there pays off across both exam parts simultaneously.

Who Actually Uses This Credential

The GB-2/GB-98 combination license is aimed at individuals seeking to operate as a licensed General Building contractor in New Mexico - meaning the license authorizes broader building scope than a narrower specialty classification. In practice, this covers people running or planning to run their own general contracting business, project managers moving into ownership roles, and tradespeople with enough field hours who want to formalize their ability to bid and manage general building projects legally. Because the license ties directly to New Mexico's regulatory framework, it's specific to contractors operating within the state rather than a portable national credential.
