What Does the Arizona CR-48 Classification Cover?

The CR-48 classification covers residential and commercial ceramic, plastic, and metal tile work.

The scope allows a licensed contractor to prepare surfaces as required to install or repair tile products on horizontal and vertical surfaces.

Covered materials include:

• Ceramic tile.
• Clay tile.
• Faience tile.
• Metal tile.
• Mosaic tile.
• Glass mosaic tile.
• Paver tile.
• Plastic tile.
• Quarry tile.
• Stone tile such as marble and slate.
• Terrazzo.

Installation of shower doors and tub enclosures is also included when that work is part of the original contract.

Step 1: Confirm CR-48 Is the Classification You Need

Arizona has multiple specialty classifications that can touch flooring, remodeling, stone, and finish work, so verify your intended license before ordering books.

CR-48 is specifically focused on ceramic, plastic, metal, mosaic, stone, quarry, paver, terrazzo, and related tile installation and repair.

Arizona currently lists CR-48 as requiring three years of qualifying hands-on and/or managerial experience. The classification also requires the Arizona Statutes and Rules Exam and the trade examination unless an approved waiver applies.

That experience requirement matters because passing the test is only one part of qualifying for the license.

Review the Arizona Registrar of Contractors classification requirements before beginning the licensing process.

Step 2: Understand the CR-48 Exam Numbers

That is enough time if you know your subject and your references. It becomes much tighter when every question turns into a five-minute search mission.

Your study plan should therefore train two skills at the same time: understanding tile installation and finding information quickly.

Step 3: Learn the CR-48 Exam Breakdown

The current PSI outline divides the 80 scored questions into six subject areas.

Tile Installation and General Tile Knowledge combine for 53 of the 80 questions. That is more than two-thirds of the exam.

If you only remember one thing when building your study calendar, remember that number.

Step 4: Make Tile Installation Your Top Priority

With 33 questions, Tile Installation is the biggest category by a wide margin.

Your preparation should include:

• Surface preparation.
• Substrates.
• Mortar beds.
• Backer materials.
• Wall installations.
• Floor installations.
• Wet-area installations.
• Tile layout.
• Movement accommodation.
• Expansion and movement joints.
• Setting methods.
• Coverage requirements.
• Tile placement.
• Cutting and fitting.
• Transitions.
• Installation tolerances.
• Preparation before grouting.

Learn why an installation method is selected instead of memorizing random steps.

When you understand how the substrate, tile type, environment, mortar, joint arrangement, and installation method work together, technical questions become much easier to solve.

Step 5: Build Strong General Tile Knowledge

General Tile Knowledge contributes 20 questions, making it the second-largest category.

Study the differences between common tile and stone products, including their characteristics, uses, limitations, and installation needs.

You should be comfortable with terminology involving:

• Ceramic tile.
• Porcelain-type products.
• Quarry tile.
• Mosaic tile.
• Glass mosaic.
• Stone products.
• Marble.
• Slate.
• Terrazzo.
• Pavers.
• Metal tile.
• Substrates.
• Mortar and bonding materials.

General knowledge questions may not always send you directly to one obvious table. Some are based on trade knowledge and standard industry practices.

This is why experience and study references still matter even on an open-book exam.

Step 6: Study Grout and Finishing Carefully

Grout and Finishing makes up 10 questions, which is one-eighth of the entire test.

Review subjects such as:

• Grout types.
• Joint preparation.
• Grout mixing.
• Application.
• Joint filling.
• Cleaning.
• Finishing.
• Curing.
• Movement joints.
• Sealant locations.
• Common grout problems.

Pay attention to the difference between a grout joint and a movement joint. They may look like lines between tiles, but they do not necessarily perform the same job.

A beautiful tile installation can still fail if movement is handled incorrectly. Tile is tough, but it is not famous for being flexible about bad decisions.

Step 7: Understand Adhesives and Bonding Materials

Adhesives account for seven questions.

Review the different bonding materials used for tile installation and the conditions that affect their selection.

Study:

• Mortar types.
• Adhesives.
• Bonding requirements.
• Mixing.
• Pot life.
• Open time.
• Trowel selection concepts.
• Coverage.
• Substrate compatibility.
• Environmental conditions.
• Tile size and material considerations.

The ANSI installation standards are especially important for understanding specifications involving setting materials and installation methods.

Step 8: Practice Plan Reading and Estimating

Plan Reading and Estimating contains only five questions, but these can be useful points if your construction math is solid.

Practice:

• Reading dimensions.
• Finding floor and wall areas.
• Calculating square footage.
• Converting measurements.
• Estimating tile quantities.
• Adding reasonable waste.
• Calculating trim quantities.
• Reading plans and elevations.
• Understanding project notes.
• Recognizing layout information.

Always read the units before calculating.

A perfectly executed calculation using the wrong dimensions is still a perfectly wrong answer.

Step 9: Do Not Give Away the Safety Questions

Safety and Employee Protection accounts for five questions.

Review OSHA construction requirements involving:

• Personal protective equipment.
• Eye protection.
• Respiratory hazards.
• Silica exposure.
• Cutting equipment.
• Electrical hazards.
• Ladders.
• Scaffolds.
• Housekeeping.
• Material handling.
• Tool safety.

Tile contractors work with saws, grinders, dust, heavy materials, chemicals, ladders, and wet environments. Safety questions are not filler. They relate directly to everyday jobsite conditions.

Step 10: Get the Correct CR-48 Reference Materials

The CR-48 content outline currently linked by PSI identifies several references that candidates may use in the examination center.

The approved list includes:

• 29 CFR Part 1926 OSHA construction regulations, with the latest available amendments, or the applicable PSI selections.
• International Residential Code for One- and Two-Family Dwellings, 2018 Edition.
• ANSI A108/A118/A136.1:2017, American National Standard Specifications for the Installation of Ceramic Tile.
• Handbook for Ceramic Tile Installation, 2017, Tile Council of North America.

You can browse the Arizona contractor books and exam prep resources from Contractor Exam Preps while assembling your CR-48 study materials.

Step 11: Know Which Books Are Study-Only References

PSI also identifies useful references that are used for exam development but are not allowed in the examination center.

The currently linked CR-48 outline lists:

• Setting Tile, 1995, by John Byrne.
• Builder's Guide to Floors, 1997, by Peter Fleming.
• Craft Training for the Tile Professional - Tub Surrounds, National Tile Contractors Association.
• Tile Manual, 1991, Ceramic Tile Institute of America.

These references can still help you understand tile methods, floors, tub surrounds, and general installation practices during your preparation.

Just remember the important distinction: a book used to prepare exam questions is not automatically a book you may carry into the testing center.

Step 12: Learn the TCNA Handbook

The Tile Council of North America handbook should become one of your most familiar references.

Do not simply flip through it and admire the diagrams.

Learn how installation methods are organized. Practice identifying a project condition and locating the method that applies to it.

Pay attention to:

• Floor methods.
• Wall methods.
• Wet-area methods.
• Substrate requirements.
• Movement joints.
• Membranes.
• Mortar-bed systems.
• Backer-board systems.
• Installation details.
• Method limitations.

A good practice question should train you to recognize both the installation problem and where the handbook organizes the answer.

Step 13: Learn the ANSI Tile Standards

ANSI A108/A118/A136.1 contains technical installation standards and material specifications that are highly relevant to the CR-48 exam.

Candidates should become comfortable locating information related to:

• Installation procedures.
• Setting materials.
• Mortars.
• Adhesives.
• Grouts.
• Substrate preparation.
• Application requirements.
• Workmanship.

The document can feel technical at first. That is exactly why repeated navigation matters.

During practice, identify a keyword from the question before opening the standard. Search by subject instead of flipping randomly and hoping the correct paragraph waves at you.

Step 14: Prepare Your Open-Book References Correctly

PSI allows candidates to prepare approved references before the examination.

Approved references may be:

• Highlighted before the exam.
• Underlined before the exam.
• Annotated before the exam.
• Indexed before the exam.
• Tabbed with permanent tabs.

PSI defines permanent tabs as tabs that would tear the page if removed.

Temporary tabs, Post-it notes, and other tabs that can be removed without damaging the page are not allowed.

Candidates may not bring unauthorized loose or attached papers with approved references.

Downloaded approved references may be used when properly bound, such as spiral binding or hole punching and placing the pages in a binder.

Do your highlighting, indexing, annotating, and tabbing before exam day. PSI does not allow candidates to continue marking references during the examination.

Step 15: Use a Four-Week CR-48 Study Plan

Adjust the schedule to fit your background. An experienced installer may know tile methods well but need more practice navigating ANSI or OSHA. Someone with strong book knowledge may need more practical installation review.

Step 16: Practice Under the Real Three-Hour Limit

At least some practice tests should copy the real exam structure.

Set a timer for 180 minutes and work through 80 questions.

Use a two-pass strategy:

1. First pass: Answer questions you know or can research quickly.
2. Second pass: Return to questions requiring longer calculations or deeper reference searches.

Do not let one question consume seven or eight minutes unless you have already secured the easier points.

Open-book testing rewards good time management. The books are there to help you, not to become a three-hour reading assignment.

Step 17: Watch for Small Words With Big Consequences

Read every CR-48 question carefully.

Pay special attention to words such as:

• MINIMUM
• MAXIMUM
• FIRST
• MOST
• LEAST
• NOT
• EXCEPT
• REQUIRED
• PROHIBITED

A question asking what is required is different from one asking what is generally recommended.

A question asking for an exception is basically wearing a tiny disguise. Make sure you spot it before answering.

Step 18: Know the Current Retake Rules

If you do not pass the trade examination, current PSI rules require a 30-day waiting period before retaking the failed exam.

Candidates currently receive three attempts to pass each examination. After three failed attempts, a 90-day waiting period applies before another attempt.

PSI provides diagnostic information after an unsuccessful examination.

Use it.

If Tile Installation was your weakest category, focus on Tile Installation before retesting. Spending another week studying the section you already crushed may feel pleasant, but it is not fixing the problem.

Step 19: Remember the Arizona Statutes and Rules Exam

CR-48 licensing also involves the Arizona Statutes and Rules Exam when required.

The SRE is a computer-based course and examination maintained by the Arizona Registrar of Contractors. It focuses on Arizona contractor statutes and rules rather than tile installation.

Current PSI information lists the SRE cost at $61.

The current trade examination fee for one examination is $66.

Exam waivers can apply under certain circumstances, so check your exact eligibility instead of assuming your requirements match another contractor's application.

Review the Arizona ROC contractor licensing instructions before scheduling and applying.

Step 20: Passing the Exam Is Only Part of Getting Licensed

Passing CR-48 is an important milestone, but the exam score does not automatically create a contractor license.

The complete Arizona process can include:

• Choosing the correct classification.
• Designating a qualifying party.
• Documenting the required qualifying experience.
• Completing the SRE when required.
• Passing the CR-48 trade exam.
• Completing required background checks.
• Obtaining the appropriate contractor license bond.
• Providing required business information.
• Providing required identification.
• Submitting the Arizona ROC license application.
• Paying applicable licensing fees.

PSI currently instructs candidates to complete licensing requirements and submit the completed license application and original score report to the Arizona Registrar of Contractors within two years of passing the examination.
