- The KBT is 125 four-option questions in 2 hours; you need 92/125 (73.6%) to pass.
- Sealants and Gaskets / Ancillary Materials is the single largest domain at 21% of the KBT.
- Certification requires the KBT plus three PBT sections: Curtainwall, Storefront/Entrance, and Sealing.
- Eligibility needs 7,500 glazing hours in five years (or 7,000 to test early) plus OSHA 10.
Quick-Reference Snapshot
This is the one-page version of everything you need to remember about the Architectural Glass & Metal Technician (AGMT) credential heading into a test date. AGMT is administered by Administrative Management Systems, Inc. with oversight from the AGMCC, and the current record is governed by the January 14, 2026 Candidate Handbook and the September 15, 2025 KBT Study Guide. If you want the long-form breakdown of any line item below, the AGMT Study Guide 2026 and AGMT Requirements 2026 articles go deeper - this page is meant to be the fast-scan version you keep open the week before your exam.
KBT Format at a Glance
The KBT is the knowledge half of certification, delivered at a Prometric or approved test center. It's closed-book, offered in English and Spanish, and a non-scientific calculator is supplied - you don't bring your own.
- Question count: 125 graded, four-option multiple-choice items
- Time limit: 2 hours
- Beta items: additional unscored questions may appear and are indistinguishable from graded ones
- Passing score: 92 correct out of 125 (73.6%)
- Retake fee: $250 if you need another attempt
Every question on the KBT maps to one of the seven domains below, so the fastest way to raise your score is to know exactly how much weight each domain carries. For a full walkthrough of question style and sample topics per domain, see the AGMT Exam Domains 2026 guide.
The Seven Domains, Ranked by Weight
Treat this table as your allocation map: study time should roughly mirror exam weight, with extra attention on the top three domains since they account for more than half the graded items.
| Domain | Weight |
|---|---|
| Sealants and Gaskets / Ancillary Materials | 21% |
| Systems | 18% |
| Quality Control / Failure Prevention | 16% |
| Glass and Panels | 14% |
| Glazing Theory | 11% |
| Construction Documents and Layout | 11% |
| Tools / Equipment of the Trade | 9% |
Sealants and Gaskets / Ancillary Materials (21%)
The largest domain on the KBT. Candidates need to know compatibility, cure behavior, and application context for the materials that keep a glazed assembly weathertight.
- Sealant chemistries and where each is appropriate
- Gasket types and their role in structural vs. dry-glazed systems
- Ancillary materials such as setting blocks, shims, and spacers
Systems (18%)
Covers the assemblies a technician actually installs day to day - curtainwall, storefront, entrances, and window wall - and how their components interact.
- Framing member function within a given system type
- Anchorage and structural connection points
- System-specific tolerances and installation sequencing
Quality Control / Failure Prevention (16%)
Focused on catching problems before or during installation rather than after the building is occupied.
- Common failure modes in sealant joints and glazing pockets
- Inspection checkpoints during installation
- Corrective actions when tolerances are out of spec
The remaining four domains - Glass and Panels, Glazing Theory, Construction Documents and Layout, and Tools/Equipment of the Trade - are lighter but still regularly tested. A candidate who ignores any single domain risks missing enough points to fall short of 92/125. Skimming any domain because it's "only 9%" is a common way people underperform relative to their hands-on skill level; the How Hard Is the AGMT Exam? breakdown discusses this pattern in more detail.
PBT Section Cheat Sheet
Passing the KBT alone does not make you certified. You also need to pass all three performance-based test (PBT) sections, which evaluate hands-on glazing work rather than multiple-choice recall.
| PBT Section | Time Allowed | Passing Score |
|---|---|---|
| Curtainwall | 3 hours 30 minutes | 462/600 |
| Storefront/Entrance | 2 hours | 321/425 |
| Sealing | 45 minutes | 79/100 |
Key Takeaway
Passed PBT sections are retained within the handbook's retake period, so if you clear Curtainwall but need another attempt at Sealing, you don't have to redo the sections you already passed.
Passing Score Quick Math
Keep these numbers on hand - they're the ones candidates most often misremember under pressure:
- KBT: 92 out of 125 correct (73.6%)
- Curtainwall PBT: 462 out of 600 points
- Storefront/Entrance PBT: 321 out of 425 points
- Sealing PBT: 79 out of 100 points
For the reasoning behind these thresholds and how scoring works across sections, the AGMT Passing Score 2026 article covers it in full.
Fees & Registration Mechanics
Under the USD fee schedule effective July 1, 2026, plan on the following costs when budgeting for certification:
- KBT fee: $250
- PBT fee: $1,000 (covers all three sections)
- Business-account fee: $150
- Initial total before extras: $1,400
Retake pricing is section-specific on the PBT side, which rewards passing as many sections as possible on your first attempt:
- KBT retake: $250
- One PBT section retake: $550
- Two PBT sections retake: $900
- All three PBT sections retake: $1,000
Eligibility Checklist
Before you can sit for either exam component, confirm you meet these requirements:
- 7,500 hours of glazing work experience within the past five years
- OSHA 10 certification, or qualifying Canadian safety training equivalent
- A signed candidate agreement
Candidates who have logged at least 7,000 hours can test early, but must document completion of the full 7,500-hour requirement within 12 months of passing the PBT. This early-testing path is worth understanding fully before you schedule anything - see the AGMT Requirements 2026 article for the documentation process.
Renewal & CE Snapshot
AGMT certification is valid for four years. To renew, you need:
- A current, passing KBT result
- 32 continuing-education hours total, split as 16 hours per two-year segment
- 4,000 work hours during the certification term, or a PBT retest in lieu of hours
- The standard renewal package fee of $600
Because renewal ties CE hours to specific two-year segments rather than letting you cram them all at the end, it's worth tracking progress annually rather than waiting until the four-year mark approaches.
Final-Week Review Plan
If your exam is close and you need a compressed schedule, allocate review time by domain weight rather than by how comfortable each topic feels. This is one of the few places generic study techniques are useful - spaced repetition on flashcards works well specifically because the KBT draws so heavily from two domains.
Sealants and Gaskets / Ancillary Materials
- Drill compatibility charts and cure-time scenarios - this is 21% of the KBT
- Review gasket selection for structural vs. dry-glazed assemblies
Systems + Quality Control / Failure Prevention
- Walk through curtainwall, storefront, and window wall assemblies
- Pair each system with its most common failure mode
Glass and Panels, Glazing Theory, Documents, Tools
- Timed practice questions across the four lighter domains
- Flag any domain where you're missing more than one in four questions
Full Simulation + PBT Mental Walkthrough
- Take a full-length timed practice run on the AGMT practice test
- Mentally rehearse Curtainwall, Storefront/Entrance, and Sealing sequencing
For a longer-horizon plan that doesn't assume you're cramming, the AGMT Study Guide 2026 lays out a full multi-week approach.
Cheat-Sheet Mistakes to Avoid
- Confusing the KBT passing score with a PBT passing score. They're different scales (73.6% vs. point totals per section) - don't study one number and assume it applies everywhere.
- Assuming all PBT sections carry equal weight. Curtainwall's 3.5-hour window and 600-point scale make it a very different exam experience than the 45-minute Sealing section.
- Underestimating a low-percentage domain. Tools/Equipment of the Trade is only 9%, but it's still roughly 11 questions on a 125-question exam - enough to matter if you skip it entirely.
- Forgetting the 12-month documentation window. If you tested early at 7,000 hours, missing the follow-up documentation deadline can jeopardize your certification.
- Not budgeting for the business-account fee. The $150 fee is easy to overlook when adding up KBT and PBT costs separately.
Frequently Asked Questions
Run a full timed practice session that mirrors the 125-question, 2-hour format, then compare your weak domains against the weight table above. Heavy misses in Sealants and Gaskets or Systems should get priority review before test day.
No. They're separate components with separate fees and scheduling. Many candidates pass the KBT first, then move on to the three PBT sections - Curtainwall, Storefront/Entrance, and Sealing - once hands-on prep is ready.
Passed sections are retained within the handbook's retake period, so you'd only need to retake the failed section. A single-section PBT retake costs $550 under the current fee schedule.
Yes, if you have at least 7,000 hours. You'll need to document completion of the full 7,500-hour requirement within 12 months of passing the PBT.
AGMT certification lasts four years. Renewal requires a current passing KBT, 32 CE hours (16 per two-year segment), and either 4,000 work hours during the term or a PBT retest, plus a $600 standard renewal fee.
