Exam Details

The Virginia Glass and Glazing Contracting examination is administered through PSI as part of the Virginia Department of Professional and Occupational Regulation Board for Contractors licensing process. GLZ is one of the Virginia specialty designations that requires a qualified individual to receive the applicable approval and successfully complete a technical examination.

The current PSI Glass and Glazing examination outline lists 45 questions, a 100-minute time allowance, and a minimum passing score of 70%.

The published content outline is divided into six subject areas. General Glazing includes 12 questions. Glass Systems includes 10 questions. Plastics and Acrylics includes 4 questions. Sealant Installations includes 4 questions. Safety includes 5 questions. Code Requirements includes 10 questions.

General Glazing and Glass Systems represent a significant portion of the examination. Candidates should understand glazing terminology, materials, installation practices, glass types, framing systems, glazing methods, and the practical considerations involved in installing glass safely and correctly.

Code Requirements also account for 10 questions. Candidates should therefore become comfortable using the International Building Code and identifying provisions that apply to glass, glazing, safety glazing, openings, guards, doors, and other building conditions involving glass products.

Safety contributes another important portion of the examination. Glass work presents risks involving handling, lifting, sharp edges, elevated work, ladders, scaffolds, personal protective equipment, power tools, and material storage. OSHA study should be incorporated throughout preparation instead of treated as a separate subject at the end.

Open Book Test

The Virginia Glass and Glazing Contractor examination is an open-book test. Candidates are responsible for bringing their own permitted references to the examination center because the testing site does not provide the books.

PSI allows approved reference materials to be highlighted, underlined, and indexed before the examination. Permanent tabs may be used for indexing. Removable tabs and temporary flags are not permitted.

Reference materials must otherwise remain unmarked, and written notes are not allowed. Loose papers and unbound materials are also restricted. Candidates using downloaded material must prepare it in a bound format that complies with PSI testing requirements.

The open-book format makes reference navigation an important part of exam preparation. Candidates should practice locating information before test day instead of relying on the assumption that every answer can be researched easily during the examination.

A code question involving safety glazing or glass in a hazardous location may point toward the International Building Code. A question about glazing methods, glass selection, or installation practices may require the Glazing Manual. A question focused on model-code glazing requirements may be supported by the Guide to Glass & Glazing Requirements of the Model Building Codes.

OSHA questions may involve ladders, scaffolding, fall protection, personal protective equipment, material handling, tools, or other jobsite safety requirements. Learning which reference applies to each type of question can reduce unnecessary searching.

Practice using the table of contents, indexes, chapter headings, code sections, diagrams, charts, and technical terminology in each book. The goal is to turn the references into familiar working tools before examination day.

Licensing Steps

Virginia contractor licensing is administered by the Department of Professional and Occupational Regulation through the Board for Contractors. A contractor license is issued to the business and includes both a license class and one or more classifications or specialty designations.

Applicants pursuing Glass and Glazing Contracting must identify a qualified individual for the GLZ specialty. Virginia requires GLZ qualified individuals to receive pre-approval and pass the applicable specialty examination.

The qualified individual must have the required relationship with the contracting business. Virginia requires the qualified individual to be either a full-time employee working at least 30 hours per week or a member of responsible management.

The qualified individual must also meet the minimum experience requirement associated with the contractor license class being requested. Virginia requires at least one year of applicable experience for Class C, three years for Class B, and five years for Class A.

An Experience Verification Form is required for qualified individuals applying for specialty designations that require pre-approval for an examination, including Glass and Glazing Contracting. The experience should relate to the specialty for which the individual is qualifying.

After the applicable examination approval is obtained, the qualified individual schedules and completes the GLZ specialty examination through PSI. Successful completion of the exam satisfies the technical examination requirement associated with the specialty.

Virginia also requires eight hours of approved pre-license education for new contractor licenses. Class A and Class B applicants have separate business examination requirements associated with the designated employee. These requirements are distinct from the GLZ specialty examination.

After the applicable education, experience, examination, business, financial, and application requirements are completed, the contractor submits the licensing materials to the Virginia Board for Contractors for review.

State Requirements

Virginia defines Glass and Glazing Contracting as the service that provides for installation, assembly, repair, improvement, or removal of all makes and kinds of glass, glass work, mirrored glass, and glass substitutes used for glazing.

The specialty also includes fabrication and glazing of frames, panels, sashes, and doors and installation of those items in structures. Standard methods of weatherproofing, caulking, glazing, sealants, and adhesives are included within the GLZ specialty scope.

Virginia's Residential Building and Commercial Building classifications also provide for glass and glazing work within their broader scopes. The Home Improvement and Commercial Improvement specialties also include this function when performed within the scope authorized by those designations.

The GLZ specialty is focused specifically on glass and glazing work. Applicants should select the classification or specialty that matches the range of services the contracting business intends to provide.

Virginia licenses contractors as Class A, Class B, or Class C. The license class determines the monetary level of contracts or projects the business may undertake, while the classification or specialty determines the type of work the contractor is authorized to perform.

The qualified individual for GLZ must satisfy the experience and examination requirements applicable to the specialty. The business must separately satisfy all requirements associated with the contractor license class being requested.

Test Information and Study Materials

A productive Virginia GLZ preparation plan should begin with General Glazing and Glass Systems because these areas represent 22 of the 45 questions on the current content outline. Candidates should review glass types, glazing materials, installation procedures, framing conditions, system components, and common glazing terminology.

General glazing preparation should include proper handling, measurement, installation techniques, glazing methods, materials, and practical field procedures. Candidates should understand the purpose of glazing components and how different materials work together in a completed installation.

Glass Systems preparation should include storefronts, frames, panels, doors, assemblies, glazing systems, and related installation concepts. Review the relationship between glass products, framing, sealants, setting materials, and supporting components.

Code Requirements account for 10 questions. Candidates should become familiar with the organization of the International Building Code, especially provisions affecting glass and glazing. Practice finding requirements involving safety glazing, hazardous locations, doors, panels, guards, walls, and other conditions in which glass is regulated.

Plastics and Acrylics account for 4 questions. Candidates should understand the characteristics and uses of glazing substitutes and related plastic materials. Review how these products differ from traditional glass and what installation considerations may apply.

Sealant Installations also account for 4 questions. Study sealant selection, joint preparation, substrate conditions, application, compatibility, weatherproofing, and the role of sealants and adhesives in glazing systems.

Safety includes 5 questions. Glass can be heavy, fragile, and sharp, and glazing operations frequently occur on ladders, scaffolds, lifts, and elevated building openings. Review personal protective equipment, material handling, fall protection, ladders, scaffolds, tools, and other OSHA subjects relevant to glazing crews.

After reviewing the individual content areas, move into mixed-reference practice. Read a question, determine whether it is primarily a glazing-method, glass-system, code, sealant, plastic, or safety question, then select the reference most likely to contain the answer.

This process helps develop the combination of trade knowledge and book-navigation skills needed for an open-book examination. Repeated practice can make a four-book package feel much more manageable by exam day.
