What You Get

The CR-37 exam preparation process should focus on how plumbing systems are installed, altered, repaired, protected, tested, and coordinated with related fuel gas, mechanical, sprinkler, wastewater, boiler, hydronic, and underground utility requirements. Plumbing work can involve water supply, drainage, venting, fixtures, appliances, pressure vessels, piping, pumps, valves, supports, hangers, cleanouts, traps, gas piping, hydronic piping, wastewater systems, excavation awareness, and jobsite safety.

Open-book contractor exams require more than field experience. A contractor may understand plumbing work from years on the job but still need practice using technical references under timed exam conditions. The exam may ask about code requirements, pipe sizing, fuel gas systems, hydronic heating, sprinkler references, wastewater provisions, OSHA safety, boiler operation, fittings, valves, calculations, or underground utility procedures. Strong preparation means knowing which reference applies to each question and how to locate the correct information efficiently.

Exam Details

Arizona contractor trade examinations are administered through PSI for the Arizona Registrar of Contractors. The CR-37 Plumbing classification is a dual residential and commercial contractor classification tied to plumbing work. Students preparing for the CR-37 exam should focus on plumbing code, fuel gas code, mechanical code, fire sprinkler standards, on-site wastewater provisions, hydronic heating, boilers, pipe trade math, pipe trade reference data, OSHA construction safety, and practical jobsite knowledge.

The exam is based on trade knowledge and approved reference materials. Students should be prepared for questions involving water supply, drainage, venting, fixtures, appliances, piping, fittings, valves, supports, materials, fuel gas systems, mechanical systems, hydronic heating, sprinkler installation references, boiler concepts, wastewater rules, underground utility awareness, construction safety, pipe calculations, and plumbing installation practices. Because CR-37 is a dual classification, preparation should include both residential and commercial applications within the plumbing trade.

PSI contractor exams are computer-based. Candidates answer questions on screen and use approved reference materials during the exam. This testing format requires both trade understanding and reference-navigation skill. Students should prepare by reviewing the course, studying the references, practicing exam-style questions, and learning how each book is organized before test day.

Arizona contractor licensing may also require the Arizona Statutes and Rules Exam, depending on the applicant and qualifying party requirements. The trade exam is one part of the licensing process. Passing an exam does not automatically issue a contractor license. Applicants must still complete the Arizona Registrar of Contractors application process and satisfy the requirements that apply to the CR-37 classification.

Open Book Test

The Arizona CR-37 Plumbing Residential / Commercial Contractor trade exam is an open-book style exam using approved references. Open-book testing gives candidates access to reference materials during the exam, but it still requires preparation, organization, and speed. Students need to understand the trade, recognize which book applies to a question, and locate information efficiently while working under exam conditions.

Each reference in this package supports a different part of the study plan. OSHA 29 CFR Part 1926 supports construction safety topics. The International Fuel Gas Code supports fuel gas system requirements. The International Mechanical Code supports mechanical system requirements and hydronic-related code concepts. The International Plumbing Code supports plumbing system requirements. The NFPA sprinkler references support fire sprinkler system study across commercial, one- and two-family dwelling, manufactured home, and low-rise residential occupancy applications. The Arizona on-site wastewater reference supports wastewater treatment facility provisions. Mathematics for Plumbers and Pipefitters supports trade math and calculation practice. IPT’s Pipe Trades Handbook supports pipe, fittings, valves, dimensions, symbols, and technical reference data. Boiler Operator’s Guide supports boiler operation and system concepts. Arizona 811 - Arizona Blue Stake Brochure supports underground utility awareness. Modern Hydronic Heating supports hydronic heating principles for residential and light commercial buildings.

Students should practice recognizing the correct reference before searching for an answer. A safety question may belong in OSHA. A plumbing code question may belong in the International Plumbing Code. A fuel gas question may belong in the International Fuel Gas Code. A mechanical or hydronic code question may belong in the International Mechanical Code. A sprinkler question may require one of the NFPA 13 references. A wastewater question may point to the Arizona Administrative Code wastewater provisions. A calculation question may require Mathematics for Plumbers and Pipefitters. A pipe data question may belong in IPT’s Pipe Trades Handbook. A boiler or hydronic heating question may point to the boiler or hydronic heating references.

Book organization matters. Students should become familiar with each book’s table of contents, index, chapter layout, definitions, tables, figures, diagrams, formulas, and common subject headings. When permitted by testing rules, permanent tabs can help speed up navigation. A useful tabbing system should be clean and focused on major exam topics instead of overloaded with labels that slow down the search process.

Licensing Steps

The Arizona CR-37 licensing path begins with selecting the correct contractor classification. CR-37 is the dual residential and commercial classification for plumbing work. Contractors preparing to perform plumbing work in both residential and commercial settings should make sure this classification matches the work they plan to perform before beginning the exam and application process.

After identifying the correct classification, the qualifying party prepares for the required examination path. This may include the CR-37 trade examination and the Arizona Statutes and Rules Exam. Candidates should study from the approved references connected to the classification and follow the current scheduling process through the approved testing provider.

Once examination requirements are completed, the applicant moves forward with the Arizona Registrar of Contractors license application. The application process may include business information, qualifying party information, financial responsibility requirements, bonding, background-related requirements, fees, and other supporting documentation required by the state. The exact application requirements depend on the applicant, business entity, qualifying party status, and license classification.

Starting preparation early helps students build a stronger study routine. With 6 months of course access, candidates can review lessons, study the books, work through practice questions, revisit difficult areas, and improve reference-navigation speed before exam day. This approach is especially helpful for experienced plumbing professionals who understand the field but need to prepare for the timing and structure of a licensing exam.

State Requirements

The Arizona Registrar of Contractors issues commercial, residential, and dual contractor licenses. The CR-37 Plumbing classification is a dual residential and commercial contractor classification. It is connected to plumbing work performed within the related residential and commercial plumbing scopes.

The plumbing scope is connected to installation, alteration, and repair of plumbing systems when performed within the classification limits. Study areas may include water supply, drainage, venting, gas piping, mechanical and hydronic systems, piping systems, fixtures, appliances, pressure vessels, wastewater provisions, safety, and code requirements. Students preparing for CR-37 should focus on plumbing trade knowledge, code navigation, system installation, calculation skills, and practical jobsite procedures.

Because this is a dual residential and commercial classification, students should prepare for both types of construction. Residential work may involve one- and two-family dwelling plumbing, residential sprinkler references, residential hydronic heating, and dwelling-related code requirements. Commercial work may involve larger plumbing systems, commercial code provisions, fuel gas requirements, mechanical coordination, sprinkler references, boilers, and jobsite safety. The reference list reflects the broad nature of the classification.

Arizona licensing approval is separate from exam preparation. The state determines whether an applicant qualifies for the license, whether the qualifying party requirements have been met, and whether the application is complete. This package supports exam preparation, but applicants must still follow the Arizona Registrar of Contractors licensing process and satisfy the requirements that apply to the CR-37 classification.

Test Information and Study Materials

Effective CR-37 exam preparation should combine trade review, code study, safety review, math practice, pipe reference navigation, hydronic heating study, sprinkler reference study, wastewater provision review, and open-book navigation practice. Students should begin by learning what each book is used for. OSHA supports safety questions. The fuel gas, mechanical, and plumbing codes support code questions. The NFPA references support sprinkler-related questions. The Arizona wastewater reference supports on-site wastewater provisions. The math and pipe trades books support calculations and reference data. The boiler and hydronic heating books support heating system concepts. The Blue Stake brochure supports underground utility awareness.

For safety topics, spend time with OSHA 29 CFR Part 1926. Plumbing work can involve excavation, trenching, ladders, tools, piping materials, equipment handling, confined or restricted work areas, personal protective equipment, and general jobsite hazards. Safety questions can be direct, so students should know how to locate OSHA rules quickly.

For plumbing code topics, use the International Plumbing Code to review water supply, drainage, venting, fixtures, traps, cleanouts, pipe materials, supports, installation requirements, and system protection. Plumbing code questions often depend on locating the correct chapter, table, definition, or exception, so repeated navigation practice is important.

For fuel gas and mechanical topics, review gas piping, appliance installation, combustion air, venting, hydronic system concepts, equipment connections, mechanical system provisions, and installation requirements. Students should be comfortable with the relationships between plumbing, mechanical, hydronic, and fuel gas systems where the references overlap.

For sprinkler topics, study the purpose of each NFPA reference. NFPA 13 supports broader sprinkler system installation requirements. NFPA 13D supports sprinkler systems in one- and two-family dwellings and manufactured homes. NFPA 13R supports sprinkler systems for certain residential occupancies up to and including four stories in height. Students should practice identifying which sprinkler reference applies before searching for an answer.

For wastewater topics, review the Arizona Administrative Code wastewater provisions in the reference list. On-site wastewater questions may involve state terminology, treatment facility provisions, permitting concepts, system requirements, and rule-based details. Students should practice using the structure of the document so they can locate information efficiently during the exam.

For math and pipe trade topics, review fractions, decimals, measurements, pipe offsets, area, volume, pressure-related calculations, fittings, valves, flanges, pipe dimensions, symbols, threads, and reference tables. Plumbing exams often include practical calculations and trade reference questions, so students should become comfortable using both Mathematics for Plumbers and Pipefitters and IPT’s Pipe Trades Handbook.

For boiler and hydronic topics, review boiler components, hot water systems, circulators, controls, heat transfer, radiant heating, piping layouts, system operation, safety devices, and basic troubleshooting concepts. Modern hydronic systems can involve multiple components working together, and students should understand both the field concepts and the reference organization.

For underground utility awareness, review Arizona 811 and Blue Stake procedures. Plumbing work often involves excavation or underground piping, and candidates should understand utility notification, marking awareness, safe digging responsibilities, and jobsite coordination before excavation begins.

Practice should include timed book-navigation drills. When answering a practice question, decide which reference applies before opening the book. Then use the table of contents, index, headings, tabs, figures, tables, and familiar sections to find the answer. This process builds the speed needed for an open-book contractor exam.

A steady study schedule is usually more effective than last-minute cramming. With 6 months of course access, students can build a routine that includes lesson review, reference reading, practice questions, safety review, code review, math practice, pipe reference drills, sprinkler study, wastewater review, hydronic heating review, and repeated exam-style practice. Consistency helps make the full reference set less overwhelming and gives students more time to strengthen weak areas before test day.
