AGMT Architectural Glass & Metal Technician Certification Exam
Summarized Exam Coverage
The AGMT exam validates experienced glaziers (minimum 7,500 hours over five years) through a written
Knowledge-Based Test (KBT) and a physical Performance-Based Test (PBT) covering: glazing theory and
safety, glass types and properties (tempered, laminated, annealed, heat-strengthened, insulating glass
units), tools of the trade, blueprint reading and layout, glass handling and lifting (vacuum cups/lifters),
installation of curtain wall, storefront, and sealant systems, structural silicone glazing, sealants (ASTM
C920), gaskets, quality control (condensation, fogging), and fall protection (OSHA Subpart M).
Certification is valid for four years .
1. When working on a swing stage at the 10th floor of a curtain wall installation, a glazier notices that
the personal fall arrest system lanyard is frayed near the connector. Under OSHA 29 CFR 1926, what is
the proper immediate action?
A) Continue working since the damage is minor
B) Tie a knot in the lanyard to shorten it
C) Remove the lanyard from service and tag it out
D) Wrap electrical tape around the damaged area
Answer: C

OSHA 1926.502(d)(9) requires damaged components to be removed from service immediately to prevent
catastrophic failure during a fall .
2. A technician is preparing to cut a large lite of 1/2″ annealed glass for a storefront replacement. Which
tool is the most appropriate for making the initial score line?
A) Electric circular saw with diamond blade
B) Hand-held glass cutter with carbide wheel
C) Angle grinder with abrasive wheel
D) Plasma cutter
Answer: B
Hand-held cutters with carbide wheels create a precise fissure for controlled breaking; power tools cause
uncontrolled fractures .
3. A spec calls for a “structural silicone glazing” (SSG) system on a high-rise office tower. What is the
defining characteristic of this type of glazing compared to a captured system?
A) Glass is held by exterior pressure plates and caps
B) Glass is supported by adhesives with minimal visible metal framing
C) Glass is bolted directly to structure with spider fittings
, Page 3 of 124
D) Glass is set on neoprene gaskets without mechanical fasteners
Answer: B
Structural silicone glazing transfers loads through sealant bonds, creating a flush, frameless appearance
.
4. An IGU installed in a northern climate is showing fogging between the panes after one year. The most
probable cause is:
A) The low-E coating was applied to the wrong surface
B) The desiccant in the spacer is saturated or the primary seal failed
C) The glass was tempered after assembly
D) The exterior silicone sealant was applied too thick
Answer: B
Desiccant maintains a dry air space; seal failure allows moisture ingress, causing condensation on the
interior surface of the outer pane .
5. While inspecting a job site, you find a 3/8″ tempered glass lite that has a 1/2″ deep chip on the edge.
The glass is scheduled for installation tomorrow. What is the correct action?
A) Proceed with installation; the chip is within typical tolerance (1/2″)
, Page 4 of 124
B) Reject the lite because edge damage can cause spontaneous breakage under thermal stress
C) Field-cut the damaged edge smooth
D) Fill the chip with structural silicone and install
Answer: B
Tempered glass has high compressive surface stress; edge damage compromises this and can trigger
explosive failure, especially under thermal or wind load .
6. New construction drawings show a double line drawn around a panel in a detail view. In blueprint
reading for glazing, a double line typically indicates:
A) A mechanical fastener
B) An Insulated Glass Unit (IGU)
C) A mullion splice
D) A structural steel backup
Answer: B
Drafting standards often represent multi-pane units (IGUs) with double lines to differentiate them from
monolithic lites shown as single lines .
