Glaziers typically enter the occupation with a high school diploma or equivalent, and learn their trade through a formal apprenticeship.
The typical training for glaziers is a 3-year apprenticeship. Each year, apprentices must have at least 144 hours of related technical training and 2,000 hours of paid on-the-job training. On the job, they learn to use the tools and equipment of the trade; handle, measure, cut, and install glass and metal framing; cut and fit moldings; and install and balance glass doors. Technical training includes instruction in glass and installation techniques as well as basic mathematics, blueprint reading and sketching, general construction techniques, safety practices, and first aid.
After completing an apprenticeship program, glaziers are considered to be journey workers who may do tasks on their own.
A few groups sponsor apprenticeship programs, including several union and contractor associations. The basic qualifications to enter an apprenticeship program are as follows:
Glaziers typically enter the occupation with a high school diploma or equivalent. High school math courses are considered useful.
Connecticut is the only state that requires licensure for glaziers. Licensure requirements include passing a test, completing an apprenticeship, and a combination of education and experience.
The National Glass Association offers a series of written exams that certify an individual's competency to perform glazier work as a Certified Glass Installer Technician.
Balance. To minimize the risk of falling, glaziers need a good sense of balance while working on ladders and scaffolding.
Hand-eye coordination. Glass must be precisely cut. As a result, a steady hand is needed to achieve a cut of the correct size and shape.
Physical strength. Glaziers must often lift heavy pieces of glass for hanging. Physical strength, therefore, is important in their work.
