Master Every Tested Subject. Pass the First Time.
California contractor exams are closed book, so the only thing walking into that testing center with you is what you’ve learned. Our California courses are built from the ground up for that reality — organized subject by subject around the official CSLB test plan, so every minute you study is aimed at what’s actually on the exam.
Prepare for your California Flooring and Floor Covering (C-15) Contractor License with 1 Exam Prep's Business & Trade Courses + Application + State Fees + 1st-Year Bond Package. This comprehensive package combines California C-15 trade examination preparation, California Law and Business examination preparation, business study books, Application Service, state licensing fees, business setup assistance, and first-year contractor license bond premium coverage up to $233.
Flooring contractors perform specialized work involving carpet, resilient flooring, laminate flooring, wood flooring, subfloor preparation, moisture testing, adhesives, and finishing procedures. Studying for the C-15 examination requires knowledge of installation methods, materials, estimating, job site conditions, and workplace safety.
Our online courses organize these subjects into focused lessons supported by videos, reading chapters, cram sheets, practice questions, and comprehensive final examinations. The additional licensing services help customers address important administrative responsibilities while preparing for both examinations.
Every tested subject gets the same four layers, in the order that makes the material stick:
Each layer reinforces the previous lesson. Students learn important flooring and business concepts, strengthen their understanding through reading, review essential information with cram sheets, and apply what they have learned through examination-style questions.
This consistent learning process helps make flooring calculations, moisture control, installation procedures, safety requirements, and contractor business responsibilities easier to organize and remember.
Once you’ve worked through every subject, the final phase pulls it all together:
Learn it. Reinforce it. Condense it. Test it. Then prove it on a full-length final — a structured preparation process created to help students strengthen retention, identify weaker subjects, and approach their first examination attempt confidently.
Comprehensive California C-15 Examination Preparation and Contractor Licensing Support
Bond Benefit: The $233 maximum applies to the first-year bond premium, not the $25,000 face amount of the standard California contractor license bond. Additional bonds and insurance obligations are separate.
The California Flooring and Floor Covering (C-15) Contractor Examination evaluates knowledge of project planning, subfloor preparation, flooring installation, concrete treatment, and workplace safety.
The official CSLB C-15 examination outline applicable to examinations scheduled on or after January 1, 2026, identifies eight major categories:
These percentages represent approximate examination content distribution. Planning and Estimating is the largest category at 21%, followed by Subfloor Evaluation, Preparation, and Material Acclimation at 20%.
The examination uses multiple-choice questions with four possible answers and one best answer. Some questions involve calculations, and a calculator is provided during testing.
Our C-15 course organizes preparation around these major examination subjects to help students study relevant technical knowledge systematically.
Both the California Flooring and Floor Covering (C-15) Trade Examination and California Law and Business Examination are closed book. Reference books, manuals, notes, and other study aids cannot be used during testing.
Because candidates must rely on retained knowledge, preparation emphasizes understanding flooring procedures, remembering material characteristics, performing calculations, recognizing safety practices, and applying contractor business concepts independently.
Our four-layer method reinforces these skills through videos, reading chapters, cram sheets, and practice questions.
Full-length final examinations help students evaluate understanding without consulting outside materials. Repeated practice offers opportunities to identify difficult subjects and strengthen examination readiness.
California Flooring and Floor Covering Contractors must obtain the appropriate C-15 specialty contractor license through the Contractors State License Board (CSLB).
Included services support licensing preparation and administration. CSLB determines application eligibility, examination results, and license issuance.
California regulates flooring contractors through the Contractors State License Board under the C-15 Flooring and Floor Covering specialty contractor classification.
C-15 contractors perform authorized flooring surface preparation and installation involving carpet, resilient flooring, wood flooring, and other established floor covering materials.
Ceramic tile installation is excluded from the C-15 classification. Contractors must understand their authorized scope of work and comply with applicable licensing requirements.
Applicants generally must demonstrate qualifying construction experience, submit appropriate CSLB application materials, and satisfy examination requirements unless an authorized exemption or waiver applies.
California requires a contractor license bond for active licensure. The standard contractor license bond has a face amount of $25,000, separate from the premium paid to obtain it.
Contractors must also follow applicable insurance, construction safety, business, and licensing requirements while operating within their classification.
The C-15 trade course is based on the following reference books (not included).
Included Business Books: California Law and Business examination study books are included with this package. The seven C-15 trade reference books listed above are not included.
Effective preparation for the C-15 examination requires knowledge of flooring materials, estimating, substrates, installation procedures, moisture management, and safety.
Planning and Estimating: Review drawings, measurements, material quantities, job site readiness, and product characteristics.
Subfloor Preparation: Study existing flooring removal, substrate evaluation, surface preparation, moisture testing, underlayments, and material acclimation.

The California Law and Business Exam Prep Online Course and business study books are included with this package.
Alongside flooring installation knowledge, California contractor applicants must understand financial, employment, legal, and administrative responsibilities.
Important Law and Business examination subjects include:
The included Law and Business course uses the same four-layer method as C-15 trade preparation, allowing students to review business concepts through organized lessons, cram sheets, and practice examinations.
This comprehensive package extends beyond examination preparation by including licensing paperwork assistance and business organization support.
Application Service: Assistance preparing and organizing the appropriate California C-15 contractor license application.
State Application Fee: Coverage of the applicable initial contractor license application fee.
Initial License Fee: Coverage of the applicable initial California contractor license fee.

These services help coordinate examination preparation with important administrative steps involved in pursuing California contractor licensure.
California requires an appropriate contractor license bond for active licensure. The standard contractor license bond has a face amount of $25,000, while the premium represents the cost of obtaining that bond.
This package includes first-year contractor license bond premium coverage up to $233, helping address an important initial licensing expense.
Bond issuance depends on the surety provider's requirements. Additional bonds may be required for particular business structures or licensing circumstances.
Workers' compensation insurance, additional bonds, and other insurance obligations are separate from the included first-year standard contractor bond benefit.
Flooring installation quality depends heavily on proper site evaluation, substrate preparation, and selecting appropriate materials.
Subfloors must be evaluated for surface irregularities, moisture conditions, and suitability for the flooring product being installed.
Carpet installation involves cushioning, tack strips, seams, stretching, and trim. Resilient flooring requires appropriate adhesives, surface preparation, rolling, and sealing.
Laminate flooring involves layout, cutting, installation, and transitions. Wood flooring requires attention to moisture testing, acclimation, installation techniques, sanding, and finishing.
Concrete treatment, dust control, material handling, and safe equipment operation are additional subjects within the C-15 examination.
Our course connects these installation topics through structured lessons designed to strengthen understanding of practical flooring procedures.
At 1 Exam Prep, we combine organized flooring trade instruction with California Law and Business preparation and licensing assistance to support your contractor licensing goals.
