The NCCER-endorsed National Glass Association (NGA)
Glazier Apprentice Curriculum is a journeyman-level
training and assessment program covering glass handling,
glazing systems, fabrication, installation, safety,
measurements, codes, storefronts, curtain walls, hardware,
sealants, and related glazing practices. The curriculum
contains more than 430 hours of training and assessments
designed by industry subject-matter experts. Successful
completion results in an NGA/NCCER credential
demonstrating knowledge and performance competency.

do first?
A. Install the units immediately to maintain schedule
B. Verify specifications before installation
C. Remove all labels and proceed
D. Apply sealant before inspection
Answer: B
Rationale: Verification prevents installation of incorrect
glass types and costly rework.
, 2.
A glazier measuring an opening obtains dimensions of 72-
5/8 inches by 48-3/16 inches. Why is measurement
accuracy especially critical before fabrication?
A. Glass can be stretched after delivery
B. Aluminum frames compensate for all errors
C. Fabricated glass dimensions cannot easily be altered
later
D. Sealants eliminate sizing issues
Answer: C
Rationale: Accurate measurements are essential because
fabricated glass has limited adjustment capability.
3.
During manual transport of a large lite across a jobsite,
which practice most effectively reduces breakage risk?
A. Carrying glass horizontally
B. Supporting glass near one corner only
C. Transporting glass vertically with proper support
D. Sliding glass across concrete
