Exam Details

The Arizona CR-70 Reinforcing Bar and Wire Mesh residential / commercial contractor exam is administered through PSI for the Arizona Registrar of Contractors. The trade exam contains 50 questions, and candidates are allowed 120 minutes to complete the test. The minimum passing score is 70%.

The official content outline includes Post-Tensioning, Reinforcing Steel - Materials, Reinforcing Steel – Placement, and Safety. Post-Tensioning includes 10 items. Reinforcing Steel - Materials includes 15 items. Reinforcing Steel – Placement includes 15 items. Safety includes 10 items.

Reinforcing Steel - Materials and Reinforcing Steel – Placement are the largest combined portion of the exam. Candidates should give these areas significant study time because rebar and wire mesh work depends on understanding material types, bar identification, handling, fabrication awareness, bar supports, spacing, lap splices, placement tolerances, concrete cover, tying, chairs, reinforcement layout, and coordination with concrete placement.

Post-Tensioning is also an important exam area. Candidates should prepare for questions related to unbonded post-tensioning fundamentals, tendons, anchorage, wedges, stressing operations, elongation awareness, tendon placement, safety around stressing operations, field handling, and inspection-related concepts. Post-tensioning work must be approached carefully because improper handling or unsafe field practices can create serious hazards.

Safety makes up 10 questions on the exam. Candidates should study OSHA construction safety rules related to reinforcing steel work, including personal protective equipment, fall protection, impalement hazards, material handling, cranes and hoisting awareness, ladders, scaffolds, tools, housekeeping, struck-by hazards, and safe work around concrete construction activities. Since the exam contains 50 questions, safety is a major part of the final score.

Open Book Test

The Arizona CR-70 Reinforcing Bar and Wire Mesh exam is an open book test. Candidates are responsible for bringing their own approved references to the examination center. 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 exam-room-approved references include Code of Federal Regulations – 29 CFR Part 1926 (OSHA), International Building Code, 2018, and International Residential Code for One- and Two-Family Dwellings, 2018. Placing Reinforcing Bars, Training and Certification of Field Personnel for Unbonded Post-Tensioning – Level 1 Field Fundamentals, and The Contractor’s Guide to Quality Concrete Construction – 4th Edition are important study references, but they are not allowed in the examination center for this exam.

Open book testing rewards candidates who study with the references before test day. Simply bringing the approved books into the testing center is not enough. Candidates should know where OSHA safety rules are located, how the IBC and IRC are organized, and how code-based requirements connect to reinforcing steel, concrete, residential construction, and commercial construction. The study-only references help candidates build practical reinforcing bar, wire mesh, post-tensioning, and concrete construction knowledge before the exam.

Licensing Steps

Arizona contractor licensing is handled by the Arizona Registrar of Contractors. A candidate pursuing the Arizona Reinforcing Bar and Wire Mesh Residential / Commercial Contractor (CR-70) license should begin by confirming that the CR-70 dual classification matches the type of reinforcing steel, wire mesh, and post-tensioning 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 reinforcing bar, wire mesh, post-tensioning, concrete construction, code awareness, and 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 references, 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.

State Requirements

The Arizona CR-70 Reinforcing Bar and Wire Mesh classification allows the scopes of work permitted by both the commercial C-70 Reinforcing Bar and Wire Mesh and residential R-70 Reinforcing Bar and Wire Mesh classifications. This dual classification is intended for contractors who perform reinforcing bar, post-tensioning, and wire mesh work in both residential and commercial settings.

The CR-70 scope allows the licensee to install or repair reinforcing bars, post-tension, and wire mesh. Candidates should understand the practical work connected to the classification, including handling reinforcing steel, placing rebar, installing wire mesh, supporting reinforcement before concrete placement, coordinating with formwork and concrete placement, following approved drawings, and observing safety requirements around reinforcing steel and post-tensioning operations.

Arizona issues separate contractor license classifications for commercial work, residential work, and dual residential/commercial work. The CR-70 classification is the dual residential / commercial reinforcing bar and wire mesh contractor classification. Applicants should make sure the classification fits the type of contracting work they plan to offer before moving forward with exam preparation and licensing paperwork.

Reinforcing work can affect concrete performance, structural strength, crack control, durability, placement quality, and jobsite safety. Poor bar placement, incorrect cover, inadequate support, careless wire mesh installation, improper tendon handling, or unsafe work practices can create serious problems. Exam preparation should reflect this responsibility by reviewing reinforcing steel materials, placement methods, post-tensioning fundamentals, concrete construction practices, building code awareness, residential code awareness, and OSHA safety.
