- The AGMT KBT passing score is 92 out of 125 scored questions - 73.6%.
- You also need to pass three separate PBT sections: Curtainwall (462/600), Storefront/Entrance (321/425), Sealing (79/100).
- Sealants and Gaskets / Ancillary Materials is worth 21% of the KBT - the single largest domain.
- KBT retakes cost $250; PBT retakes range from $550 (one section) to $1,000 (all three).
The KBT Passing Score: 92 Out of 125
If you're preparing for the Architectural Glass & Metal Technician credential, the number that matters most is 92 out of 125. That's the passing score on the knowledge-based test (KBT), which works out to 73.6%. The KBT is a closed-book, four-option multiple-choice exam administered at Prometric test centers, with 125 questions counted toward your score and a two-hour time limit. Some candidates will also see additional unscored beta items mixed into their form - these don't count for or against you, but you won't know which ones they are, so every question deserves your full attention.
The KBT is offered in both English and Spanish, and a non-scientific calculator is supplied at the testing station, so you don't need to bring your own or memorize long-division shortcuts. This is purely a knowledge test - no hands-on component - which is why the site's AGMT Study Guide 2026 exists as a companion resource for candidates who want a structured route to that 92-question threshold.
PBT Passing Scores by Section
Passing the KBT gets you halfway there. Full AGMT certification also requires passing all three sections of the performance-based test (PBT) - the hands-on component where you actually fabricate and glaze under time pressure. Each section carries its own passing score and time allowance:
| PBT Section | Time Allowed | Passing Score |
|---|---|---|
| Curtainwall | 3 hours 30 minutes | 462 / 600 |
| Storefront/Entrance | 2 hours | 321 / 425 |
| Sealing | 45 minutes | 79 / 100 |
Notice that all three cutoffs land around the same relative range - roughly 75-77% of available points. That consistency isn't accidental; it tells you the certifying process expects the same rigor whether you're being scored on a full curtainwall mock-up or a 45-minute sealing station. If you want a deeper walkthrough of what graders are actually watching for in each station, that's covered in the domain and skills breakdown at AGMT Exam Domains 2026: Complete Guide to All 7 Content Areas.
Key Takeaway
Don't think of the PBT as "the easy part because it's hands-on." The Curtainwall section alone runs 3.5 hours and requires nearly 77% accuracy across 600 possible points - that's a long, high-stakes performance window with no partial-credit forgiveness for rushed layout work.
Why 73.6% Isn't "Easy" - Domain Weighting Matters
A 73.6% passing score can sound forgiving compared to some licensing exams, but the KBT isn't evenly weighted, which changes how "easy" that number really is. Seven domains make up the KBT, and they are not equal in size:
- Domain 1: Glazing Theory - 11%
- Domain 2: Tools / Equipment of the Trade - 9%
- Domain 3: Construction Documents and Layout - 11%
- Domain 4: Glass and Panels - 14%
- Domain 5: Systems - 18%
- Domain 6: Sealants and Gaskets / Ancillary Materials - 21%
- Domain 7: Quality Control / Failure Prevention - 16%
Because Domain 6 (Sealants and Gaskets / Ancillary Materials) alone accounts for 21% of the exam, weak knowledge in that single area can make the 92-point floor much harder to clear than the raw percentage suggests. Combined with Systems (18%) and Quality Control / Failure Prevention (16%), just three of the seven domains represent 55% of the entire KBT. A candidate who is strong in Tools/Equipment (9%) but shaky on sealants and systems can still fail comfortably below 92, even while feeling "generally prepared." For a full breakdown of how each domain translates into real exam content, see AGMT Exam Domains 2026: Complete Guide to All 7 Content Areas.
Sealants and Gaskets / Ancillary Materials (21%)
The heaviest domain on the KBT. Candidates must understand compatibility between sealant chemistries and substrates, gasket profiles and durometer selection, backer rod sizing, and how ancillary materials interact with glazing systems over time.
- Structural vs. weatherseal sealant applications
- Gasket compression set and its effect on long-term seal performance
- Compatibility testing concepts between sealants, coatings, and framing materials
How Scoring Actually Works on Exam Day
The KBT's structure is straightforward once you understand the mechanics. You get 125 scored, four-option multiple-choice items in two hours - that's a little under a minute per question, which is generous for most items but tight if you get stuck rereading a lengthy scenario-based question about layout or documents. Because some forms include unscored beta questions layered in, question count on your screen may not perfectly track your progress toward the 125 scored items - don't try to guess which ones are beta and skip them; answer everything as if it counts.
There's no partial credit and no domain-by-domain minimum on the KBT itself - your 92/125 is a single composite score across all seven domains. That means strength in one domain can mathematically offset a soft spot in another, up to a point. This is different from the PBT, where each of the three sections (Curtainwall, Storefront/Entrance, Sealing) has its own independent passing score - you can't average a strong Sealing score into a weak Curtainwall score to pass overall.
Domain-by-Domain: Where Points Live
Understanding the passing score in isolation isn't enough - you need to know where the 125 questions are actually coming from so you can allocate study time proportionally. Here's how the math plays out approximately, based on the published domain weights:
- Domain 6 (21%) - roughly 26 questions on sealants, gaskets, and ancillary materials
- Domain 5 (18%) - roughly 22-23 questions on glazing systems
- Domain 7 (16%) - roughly 20 questions on quality control and failure prevention
- Domain 4 (14%) - roughly 17-18 questions on glass and panels
- Domain 1 and Domain 3 (11% each) - roughly 14 questions each on glazing theory and construction documents/layout
- Domain 2 (9%) - roughly 11 questions on tools and equipment of the trade
These aren't official per-domain question counts, but they illustrate the point: if you only need 92 correct answers and Domains 5, 6, and 7 together represent roughly 68-70 of your 125 questions, mastering those three domains gets you most of the way to a passing score by themselves. That's a strategic argument for weighting your review time toward Systems, Sealants/Gaskets, and Quality Control before polishing weaker but lower-value areas like Tools/Equipment. The AGMT Cheat Sheet 2026 is built around exactly this kind of high-yield prioritization.
What Happens If You Miss the Passing Score
Falling short of 92/125 on the KBT, or missing a PBT section cutoff, isn't the end of the process - but it does cost time and money, so it's worth understanding the retake structure before you sit for the first attempt.
- KBT retake: $250 flat, regardless of how close you were to 92.
- PBT retake, one section: $550.
- PBT retake, two sections: $900.
- PBT retake, all three sections: $1,000.
One important detail: PBT sections you've already passed are retained within the handbook's retake period. If you clear Curtainwall and Storefront/Entrance but fall short on Sealing, you only need to retest Sealing - you're not forced to redo the whole practical exam. That structure rewards candidates who prepare unevenly-but-strategically rather than punishing them for one weak section. For the complete fee schedule across initial testing and retakes, see AGMT Certification Cost 2026: Complete Pricing Breakdown.
Key Takeaway
Because retesting isn't free, treat your first attempt at both the KBT and PBT as the one that counts. A candidate who under-prepares to "save time" often ends up paying $250-$1,000 more to fix it later.
Scheduling Your Prep Around the Score Targets
Rather than studying everything evenly, build your remaining prep weeks around the domains that carry the most weight toward that 92-point threshold. A simple, weighted approach looks like this:
Sealants and Gaskets / Ancillary Materials (21%) + Systems (18%)
- Drill sealant chemistry, compatibility, and gasket selection until recall is automatic
- Review curtainwall, storefront, and window system components and their interfaces
Quality Control / Failure Prevention (16%) + Glass and Panels (14%)
- Study common failure modes and inspection checkpoints
- Review glass types, coatings, and panel handling standards
Glazing Theory, Construction Documents/Layout (11% each), Tools/Equipment (9%)
- Close remaining gaps in blueprint reading and layout math
- Run full-length practice sets timed to the two-hour KBT window
This weighting isn't a generic study hack - it's a direct response to the fact that three domains (Systems, Sealants/Gaskets, Quality Control) make up 55% of the KBT. For candidates wondering how this level of prep translates into real-world difficulty, How Hard Is the AGMT Exam? Complete Difficulty Guide 2026 walks through the exam's difficulty profile in more detail, and AGMT Pass Rate 2026: What the Data Shows looks at outcome data. You can also run full-length timed simulations on the AGMT practice test platform to see how your raw score compares to the 92/125 floor before exam day.
Eligibility and Fees Behind the Score
The passing score only matters once you're eligible to sit for the exam in the first place. AGMT requires 7,500 hours of glazing work within five years, OSHA 10 (or qualifying Canadian safety training), and a signed candidate agreement. Candidates with at least 7,000 hours can test early, but must document the full 7,500-hour requirement within 12 months of passing the PBT. Full details live at AGMT Requirements 2026: Eligibility, Prerequisites & How to Qualify.
On the fee side, initial certification runs $1,400 before extras: $250 for the KBT, $1,000 for the PBT, and a $150 business-account fee. Renewal, which comes every four years, requires a current KBT, 32 continuing-education hours (16 per two-year segment), and either 4,000 work hours during the term or a PBT retest, with a standard $600 renewal package. Administrative Management Systems, Inc. administers the program under AGMCC oversight, and the January 14, 2026 Candidate Handbook is the governing document for all of these figures.
Employers hiring architectural glass and metal technicians - glazing contractors, curtainwall subcontractors, and commercial storefront installers - generally treat the credential as proof that a technician has cleared both the knowledge floor (92/125) and the practical floor (all three PBT sections) at once.

Frequently Asked Questions
92 out of 125 scored questions, which equals 73.6%. This is defined in the January 14, 2026 Candidate Handbook and applies to the closed-book knowledge-based test only.
No. Beta items may appear alongside the 125 scored questions but don't count for or against your result. Since you can't identify which items are beta, answer every question with full effort.
Yes. Curtainwall requires 462/600, Storefront/Entrance requires 321/425, and Sealing requires 79/100. You must pass each section independently - scores don't average across sections.
No. Passed sections are retained within the handbook's retake period, so you only pay for and retest the section(s) you failed - $550 for one, $900 for two, or $1,000 if you need all three again.
Sealants and Gaskets / Ancillary Materials at 21% is the largest single domain, followed by Systems at 18% and Quality Control / Failure Prevention at 16%. Together these three domains cover more than half the exam.
