- AGMCC does not publish an aggregate AGMT pass rate - the data that exists is the scoring thresholds themselves.
- The KBT requires 92 of 125 questions correct (73.6%) in 2 hours, closed-book, English or Spanish.
- Certification also requires clearing three separate PBT minimums: 462/600 (Curtainwall), 321/425 (Storefront/Entrance), 79/100 (Sealing).
- Sealants and Gaskets / Ancillary Materials carries the heaviest KBT weight at 21%, making it the single highest-leverage study area.
Why AGMCC Doesn't Publish an Overall Pass Rate
Anyone searching "AGMT pass rate" is usually hoping for a single percentage - something like "68% of candidates pass on the first try." That number doesn't exist in any AGMCC-published material. Administrative Management Systems, Inc., which administers the Architectural Glass & Metal Technician credential under AGMCC oversight, does not release aggregate first-attempt or overall pass rate statistics for either the knowledge-based test (KBT) or the performance-based test (PBT) sections.
That's not unusual for a trade credential built around applied skills rather than a large university testing population. What the January 14, 2026 Candidate Handbook and the September 15, 2025 KBT Study Guide do publish, in detail, are the exact scoring thresholds candidates must clear. That's the real data - and it's more useful than a single percentage, because it tells you precisely how much margin you have and where the exam is structured to separate qualified glaziers from unprepared ones.
What the Published Thresholds Actually Show
Instead of a pass rate, look at what AGMCC actually built into the exam design. Certification requires passing four separate, independently scored components: the KBT and all three PBT sections (Curtainwall, Storefront/Entrance, and Sealing). Each has its own numeric cutoff. That structure alone tells you something important: this isn't a single pass/fail gate, it's a stacked set of gates, and a candidate can be strong in one area and still need work in another.
For a deeper walk-through of how the required score interacts with question count and timing, see AGMT Passing Score 2026: Exactly What You Need to Pass. For a broader look at what makes the exam challenging in the first place, How Hard Is the AGMT Exam? Complete Difficulty Guide 2026 breaks down the difficulty drivers section by section.
KBT Scoring: The 92/125 Line
The KBT is a Prometric/test-center exam: 125 graded four-option multiple-choice questions, closed-book, completed in 2 hours. Some unscored beta items may be mixed in as AGMCC evaluates future question pools, so not every question a candidate sees necessarily counts toward the score - but candidates should treat every item as if it does, since there's no way to identify beta content during the test.
The passing score is 92 out of 125, which works out to 73.6%. That means a candidate can miss 33 questions and still pass. That margin matters when you're building a study plan: it means mastery doesn't need to be perfect across all seven domains, but it does need to be strong across most of them, because missing entire domains (rather than scattering a few misses) is what tends to sink a score.
The KBT is available in English and Spanish, and a non-scientific calculator is supplied at the test center - candidates don't need to bring their own or memorize complex formulas under time pressure.
Key Takeaway
With 125 questions and a 92-correct threshold, the KBT rewards broad competence over narrow expertise. Spend the most prep time on the highest-weighted domains rather than chasing esoteric edge cases in low-weight areas.
PBT Scoring: Three Separate Bars to Clear
Passing the KBT alone doesn't make you certified. Candidates must also pass all three PBT sections, each scored independently:
- Curtainwall - 3 hours 30 minutes, passing score 462/600
- Storefront/Entrance - 2 hours, passing score 321/425
- Sealing - 45 minutes, passing score 79/100
These are the practical, hands-on stations where field experience shows. A candidate who studies hard for the written exam but hasn't spent real time on curtainwall glazing sequences, anchor placement, or proper sealant tooling technique will find the PBT unforgiving in a different way than the KBT - there's no partial credit for "knowing the theory" if the installed work doesn't meet spec.
One structural detail worth knowing: passed PBT sections are retained within the handbook's retake period. If a candidate clears Curtainwall and Sealing but comes up short on Storefront/Entrance, they don't have to redo all three - only the section that didn't meet the threshold. That retained-passing-section policy is one of the more candidate-friendly aspects of the AGMT structure.
Domain Weighting and Where Candidates Likely Struggle
The KBT is built from seven weighted domains. Weight isn't difficulty, but it is a direct signal of how many questions on the 125-item exam will come from each area - and therefore how much of your 33-question margin for error each domain can realistically absorb.
Domain 6: Sealants and Gaskets / Ancillary Materials - 21%
The single largest domain on the exam. Roughly a quarter of the KBT draws from this content area.
- Sealant chemistry, compatibility, and cure behavior
- Gasket selection and installation for weather performance
- Ancillary materials that affect long-term seal integrity
Domain 5: Systems - 18%
The second-heaviest domain, covering how glazing systems function as assemblies rather than isolated parts.
- Curtainwall, storefront, and entrance system distinctions
- Structural and thermal behavior of framing systems
Domain 7: Quality Control / Failure Prevention - 16%
Focused on catching problems before they become callbacks or safety issues.
- Common failure modes in glazing installations
- Inspection checkpoints during and after installation
Domain 4: Glass and Panels - 14%
Covers glass types, panel construction, and handling requirements.
- Glass makeup, coatings, and performance characteristics
- Panel handling and damage prevention
The remaining domains - Glazing Theory (11%), Construction Documents and Layout (11%), and Tools/Equipment of the Trade (9%) - are lighter on question count but still show up consistently, and Construction Documents in particular tends to trip up candidates who are strong in the field but less practiced at reading specs and shop drawings under time pressure. A full breakdown of every domain, with the reasoning behind each weight, is available in AGMT Exam Domains 2026: Complete Guide to All 7 Content Areas.
| Domain | KBT Weight | Relative Question Share (of 125) |
|---|---|---|
| Sealants and Gaskets / Ancillary Materials | 21% | ~26 questions |
| Systems | 18% | ~23 questions |
| Quality Control / Failure Prevention | 16% | ~20 questions |
| Glass and Panels | 14% | ~18 questions |
| Glazing Theory | 11% | ~14 questions |
| Construction Documents and Layout | 11% | ~14 questions |
| Tools / Equipment of the Trade | 9% | ~11 questions |
Who Is Actually Sitting for the AGMT
Eligibility requirements shape the candidate pool, and the candidate pool shapes outcomes. To sit for the AGMT, applicants generally need 7,500 glazing work hours within five years, OSHA 10 or qualifying Canadian safety training, and a signed candidate agreement. Applicants with at least 7,000 hours may test early, provided they document completion of the full experience requirement within 12 months of passing the PBT.
This means most people taking the AGMT are already working glaziers - installers, foremen, and field technicians employed by glazing contractors, curtainwall subcontractors, and commercial general contractors - not entry-level students studying theory in isolation. That matters for how you should read "difficulty": the exam assumes a working knowledge of tools, materials, and job-site sequencing that comes from actual hours on the wall, not just a textbook. Full eligibility mechanics are covered in AGMT Requirements 2026: Eligibility, Prerequisites & How to Qualify.
The Real Cost of Not Passing the First Time
Because there's no published pass rate, the more actionable number to plan around is the retake fee schedule - it tells you exactly what a missed attempt costs, in dollars, which is a fair proxy for how seriously to prepare.
Effective July 1, 2026, initial fees total $1,400 before extras: KBT $250, PBT $1,000, and a business-account fee of $150. If a retake is needed, the KBT retake is $250. PBT retakes are priced by how many sections need to be redone: $550 for one section, $900 for two, or $1,000 for all three. Since passed PBT sections are retained within the retake period, most candidates who fail will only owe the single-section or two-section retake rate, not the full $1,000.
A full pricing breakdown, including renewal costs, is in AGMT Certification Cost 2026: Complete Pricing Breakdown.
Key Takeaway
A single missed PBT section costs $550 to retake - not $1,000. Failing one station isn't catastrophic financially, but it's still a meaningful reason to over-prepare the KBT and rehearse each PBT station individually before test day.
A Domain-Sequenced Study Timeline
Generic study techniques only help if they're pointed at the right AGMT content in the right order. Given that Sealants and Gaskets / Ancillary Materials carries the most weight and Systems is second, those two domains deserve the earliest and heaviest attention - not the domains that feel most familiar from daily work.
Sealants and Gaskets / Ancillary Materials (21%)
- Review sealant chemistry, compatibility charts, and cure/failure conditions
- Drill gasket selection scenarios tied to weather performance
Systems (18%) and Glass and Panels (14%)
- Compare curtainwall, storefront, and entrance system requirements
- Study glass coatings, makeups, and panel handling rules
Quality Control / Failure Prevention (16%) and Glazing Theory (11%)
- Work through common failure modes and inspection checkpoints
- Reinforce foundational glazing theory concepts
Construction Documents, Tools/Equipment, and PBT Rehearsal
- Practice reading shop drawings and specs under a timer
- Run full-length mock PBT sessions for Curtainwall, Storefront/Entrance, and Sealing against the published time limits
For a more detailed week-by-week plan and recommended resources, see AGMT Study Guide 2026: How to Pass on Your First Attempt. And once your domain review is solid, running full-length timed practice sessions on the AGMT practice test platform is the closest simulation you'll get to the actual 2-hour, 125-question KBT format before walking into the test center.
FAQs
No. AGMCC and Administrative Management Systems, Inc. do not publish an aggregate pass rate for the KBT or PBT sections. The only verified figures available are the scoring thresholds themselves: 92/125 for the KBT, and 462/600, 321/425, and 79/100 for the three PBT sections.
No. Passed PBT sections are retained within the handbook's retake period, so a candidate who fails only Sealing, for example, would retake that section alone rather than Curtainwall and Storefront/Entrance again.
The KBT has 125 graded questions with a passing score of 92, meaning up to 33 incorrect answers still result in a pass. Some additional unscored beta items may appear but don't count toward this total.
Sealants and Gaskets / Ancillary Materials, at 21% of the KBT, is the single highest-weighted domain and the best return on limited study time, followed by Systems at 18%.
No, unscored beta items do not count toward the 92/125 passing threshold, but since they're indistinguishable from graded questions during the test, candidates should answer every question as if it counts.
