Approved reference materials may be highlighted, underlined, annotated, and indexed before the exam session begins. Candidates may not write, highlight, underline, or index inside the references during the examination session.

Reference books may be tabbed or indexed with permanent tabs only. Permanent tabs are tabs that would tear the page if removed. Temporary tabs, removable sticky notes, and other removable tabs are not allowed and must be removed before the exam begins. Candidates may not bring loose papers or attached papers with the approved references.

If a candidate uses a permitted reference downloaded from the internet, the material must be bound before being brought into the testing center. A bound reference may be spiral bound or hole-punched and placed in a binder when allowed by the exam instructions. Candidates may use a silent, nonprinting, non-programmable calculator in the examination center.

The approved references allowed in the exam room are Code of Federal Regulations – 29 CFR Part 1926 (OSHA), Gypsum Construction Handbook, 7th Edition, and International Building Code, 2018. Candidates should use these books during preparation, become familiar with their organization, and bring only compliant reference materials into the testing center.

Open book testing rewards students who study with the references before the exam. Simply bringing the books into the testing center is not enough. Candidates should know where OSHA safety rules are located, how the Gypsum Construction Handbook is organized, where drywall and finishing topics are explained, and how the International Building Code is structured. Students should also prepare for trade knowledge and general industry practice questions connected to acoustical systems, drywall, finishing, and safety.

Licensing Steps

Arizona contractor licensing is handled by the Arizona Registrar of Contractors. A candidate pursuing the Arizona Acoustical Systems Commercial Contractor (C-1) license should begin by confirming that the C-1 commercial classification matches the type of acoustical systems work the business intends to perform. The qualifying party must complete the examination requirements connected to the license classification.

Many Arizona contractor license applicants must complete the applicable trade exam and the Arizona Statutes and Rules Training Course and Exam. The trade exam measures acoustical systems, drywall materials, installation practices, finishing knowledge, code awareness, and construction safety knowledge for the license classification, while the statutes and rules requirement covers Arizona contractor law and regulatory responsibilities. Candidates should follow the Arizona Registrar of Contractors application process for the business structure, qualifying party, experience, bonding, and supporting documents that apply to the license being pursued.

A practical preparation path begins with identifying the correct classification, reviewing the official exam content outline, gathering the approved reference books, and setting a realistic study schedule. After preparation, the candidate schedules the trade exam through PSI and follows testing center rules for identification, reference materials, calculators, personal items, and exam-room conduct.

After the required examination steps are completed, the applicant continues through the Arizona Registrar of Contractors licensing process. This may include submitting the license application, identifying the qualifying party, providing required business information, meeting bonding requirements, and satisfying other state requirements connected to the applicant and classification.
