Nevada C-17 Lathing and Plastering Contractor Contractor - Online Exam Prep Course

Prepare for the Nevada C-17 Lathing and Plastering Contractor examination with an online exam prep course built around the trade knowledge, safety concepts, gypsum construction material, and closed-book study requirements associated with this Nevada specialty contractor classification. The course provides a structured way to review plastering, lathing, surface preparation, application methods, base and finish coats, drywall-related work, sheet-metal framing, construction safety, and other technical subjects that candidates should understand before examination day.

The Nevada C-17 Lathing and Plastering classification is regulated by the Nevada State Contractors Board. The classification covers a broad range of work involving lath, plaster, drywall, acoustical tile, stucco and cement coatings, and sheet-metal studs used for ceilings and nonstructural partition walls.

The C-17 trade examination is a closed-book examination. Candidates cannot rely on technical references during the test, so preparation should focus on understanding, retention, and practical application. The goal is to learn the material well enough to recognize correct procedures, materials, installation methods, safety requirements, and trade practices without searching a book during testing.

The primary study references for preparation are Plastering Skills, 1984; Code of Federal Regulations - 29 CFR Part 1926 (OSHA); and Gypsum Construction Handbook, 7th Edition. These materials support preparation for plaster systems, lath, surface preparation, application methods, base and finish coats, gypsum construction, drywall, sheet-metal framing, and jobsite safety.

Online exam prep gives candidates the flexibility to organize study around the major trade subjects rather than treating the C-17 examination as one large body of information. Students can review plastering systems, safety, drywall, application procedures, surface preparation, and sheet-metal topics separately and return to weaker areas as needed.

Because the examination is closed book, practice-oriented study is especially important. Candidates should work on understanding why particular procedures are used, how materials are selected and installed, and how jobsite conditions affect the completed work. Building that practical understanding makes technical information easier to recall during the examination.

Exam Details

The Nevada C-17 Lathing and Plastering trade examination is administered through PSI for candidates who receive examination eligibility through the Nevada State Contractors Board.

• Exam: Nevada C-17 Lathing and Plastering
• Number of Questions: 45
• Time Allowed: 1.5 hours
• Minimum Passing Score: 32 correct answers

The C-17 examination content outline is divided into six major technical areas:

• Safety: 5 questions
• Surface Preparation: 11 questions
• Drywall: 5 questions
• Application: 10 questions
• Base and Finish Coat: 9 questions
• Sheet Metal: 5 questions

Surface Preparation is the largest category with 11 questions. Candidates should understand how substrates are inspected and prepared before lath, plaster, stucco, gypsum, or related materials are installed. Study should include cleaning, condition of the base, bonding considerations, moisture-related conditions, attachment surfaces, and the preparation steps required before finish materials are applied.

Application contains 10 questions and is another major part of the examination. Preparation should include hand and mechanical application methods, work sequence, plaster and stucco procedures, material handling, tools, and techniques used to create a consistent finished system.

Base and Finish Coat contains nine questions. Candidates should understand the relationship between base materials, plaster coats, finish coats, curing, preparation between coats, thickness considerations, and finishing techniques.

Safety contains five questions. Candidates should review construction safety involving scaffolds, ladders, personal protective equipment, tools, fall hazards, material handling, respiratory concerns, and other jobsite conditions associated with lathing, plastering, drywall, and stucco work.

Drywall contains five questions. Study should include gypsum wallboard and sheathing, installation concepts, suspended gypsum ceilings, finishing, accessories, and practical gypsum construction subjects relevant to the broader C-17 classification.

Sheet Metal contains five questions. Candidates should review sheet-metal studs used to frame ceilings and nonstructural partition walls and understand how these framing components relate to drywall and interior finish construction.

Closed Book Test

The Nevada C-17 Lathing and Plastering trade examination is a closed-book test. The technical references used during preparation are not allowed into the examination room.

The study references are:

• Plastering Skills, 1984
• Code of Federal Regulations - 29 CFR Part 1926 (OSHA)
• Gypsum Construction Handbook, 7th Edition

Closed-book preparation requires candidates to build working knowledge before test day. Instead of planning to look up unfamiliar answers during the examination, students should use the study materials to develop recall of the trade concepts most likely to appear in exam questions.

Plastering Skills supports preparation involving lathing, plaster materials, surface preparation, mixing, application methods, base coats, finish coats, stucco, tools, and practical plastering procedures. Candidates should focus on how these subjects connect in real construction work.

OSHA 29 CFR Part 1926 supports safety preparation. Since the reference is not available during the examination, candidates should become familiar with common jobsite safety requirements involving scaffolds, ladders, personal protective equipment, fall protection, tools, material handling, and other hazards relevant to the trade.

The Gypsum Construction Handbook supports preparation for gypsum products, drywall systems, wall and ceiling construction, installation procedures, finishing, assemblies, accessories, and other gypsum-related subjects.

A useful closed-book strategy is to study by concept rather than page number. Candidates should understand the sequence of work, the purpose of specific materials, the relationship between lath and plaster systems, and the safety reasoning behind common procedures. This approach can make information easier to remember and apply during the test.

Licensing Steps

The Nevada State Contractors Board regulates the C-17 Lathing and Plastering classification. Applicants must complete the applicable contractor licensing requirements before a license can be issued.

1. Confirm the C-17 classification. Determine that Lathing and Plastering matches the type of work the contracting business intends to perform.
2. Identify the qualifying individual. Designate the person who will satisfy the trade qualification requirements for the business.
3. Document qualifying experience. Prepare appropriate records demonstrating relevant experience in lathing, plastering, drywall, stucco, sheet-metal framing, or other work directly related to the C-17 classification.
4. Prepare the contractor license application. Gather the required business information, qualifying-party documentation, financial information, and supporting records.
5. Submit the application to the Nevada State Contractors Board. The Board reviews the application and evaluates the applicant's qualifications.
6. Complete applicable background requirements. Follow the fingerprint and background procedures associated with Nevada contractor licensing.
7. Provide applicable financial information. Nevada evaluates financial responsibility as part of the licensing process.
8. Receive examination eligibility. Eligible qualifying individuals can proceed with the required examinations after Board authorization.
9. Schedule the C-17 examination through PSI. Arrange the trade examination after receiving examination eligibility.
10. Prepare for the closed-book trade examination. Review Safety, Surface Preparation, Drywall, Application, Base and Finish Coat, and Sheet Metal.
11. Prepare for contractor Business and Law. Nevada contractor applicants generally must also satisfy the Contractor Management Survey requirement unless an applicable waiver is approved.
12. Complete required examinations. Meet the applicable trade and management qualification requirements.
13. Complete final licensing requirements. Address applicable financial responsibility, bonding, and remaining Board requirements before license issuance.

Candidates should treat the examination and license application as related but separate parts of the process. Technical preparation helps with the C-17 trade test, while organized documentation supports the licensing application and qualification review.

State Requirements

The Nevada C-17 Lathing and Plastering classification includes several related types of specialty construction work. Understanding the classification scope can help candidates connect exam preparation with the work they may perform under the license.

The lathing portion includes selecting and applying wood and metal lath and other materials designed to provide a suitable base for plaster coatings. Candidates should understand how the lath system supports the plaster application and why proper installation is important to the completed surface.

The plastering portion includes coating surfaces with plaster materials and installing lath or another suitable base for plaster. Preparation should include materials, mixing, application, base coats, finish coats, curing, and finishing procedures.

The classification also includes drywall work involving the installation and coating of gypsum wallboard and sheathing, including suspended ceiling systems made of gypsum wallboard.

Acoustical tile work within the classification includes installation of appropriate acoustical materials and preparation of the surface receiving the tile. Candidates should understand how this type of finish work fits within the broader C-17 scope.

The C-17 classification also includes coatings of stucco and cement applied by manual or mechanical methods. Surface preparation, appropriate bases, application methods, and finishing procedures are therefore important trade subjects.

Sheet-metal stud work includes the installation of sheet-metal studs used to frame ceilings and nonstructural partition walls. This area is represented directly on the trade examination.

For the standard Nevada contractor licensing pathway, the Trade Qualified Individual generally must demonstrate at least four years of qualifying experience as a journeyman, foreman, supervising employee, or contractor in the requested classification.

Nevada contractor applicants must also satisfy applicable financial responsibility, background, bonding, trade qualification, and management qualification requirements before the contractor license can be issued.

  This study reference supports gypsum wallboard, sheathing, ceilings, partitions, installation, finishing, assemblies, accessories, and related gypsum construction concepts. It is not allowed into the closed-book C-17 trade examination.

These three references should be used to build technical understanding before examination day. Because candidates cannot use them during the trade test, repeated study and practice are important for developing recall.

Plastering Skills can be used to connect surface preparation, lath, plaster materials, application procedures, and finish work. Rather than studying each chapter in isolation, candidates can focus on the sequence of work from substrate preparation through the completed finish.

OSHA study should emphasize recognition of safe work practices. Candidates should be able to identify unsafe conditions and proper procedures without relying on the regulation text during the examination.

The Gypsum Construction Handbook can support preparation for the drywall portion of the exam and help candidates understand gypsum products, wall and ceiling systems, finishing procedures, assemblies, and related construction methods.

Test Information and Study Materials

A productive Nevada C-17 study plan should follow the examination content weighting while also accounting for the closed-book format. Candidates should spend the most time on the largest categories but still review every subject area.

Prioritize Surface Preparation. Surface Preparation contains 11 questions and is the largest section. Review substrates, cleaning, lath bases, bonding conditions, attachment surfaces, moisture considerations, and preparation required before coatings or finishes are applied.

Study Application procedures carefully. Application contains 10 questions. Review material handling, mixing, placement, hand and mechanical application, plastering and stucco methods, work sequence, and appropriate tools.

Understand Base and Finish Coat work. This category contains nine questions. Study the purpose and sequence of base coats, finish coats, curing, surface condition between coats, and finishing methods.

Prepare Safety for recall. Safety contains five questions. Since OSHA cannot be used during the examination, study scaffolds, ladders, PPE, fall hazards, tools, and material handling until the correct procedures are familiar.

Review Drywall. Study gypsum wallboard, sheathing, ceilings, partitions, installation, finishing, assemblies, and related materials using the Gypsum Construction Handbook.

Review Sheet Metal. Study the installation of sheet-metal studs used in ceilings and nonstructural partition walls and understand their relationship to drywall and interior finish systems.

Use active recall. After studying a topic, close the book and summarize the procedure or concept from memory. Closed-book preparation improves when candidates practice recalling information instead of only rereading it.

Work through practice-oriented questions. Use practice questions to identify weak areas. When a question is missed, return to the corresponding topic and review the underlying concept rather than memorizing the answer alone.

Practice with the examination time limit in mind. Candidates have 1.5 hours to complete 45 questions. Timed practice can help establish a steady pace and reduce the tendency to spend too long on difficult questions.

Separate trade preparation from Business and Law study. Nevada contractor licensing generally includes a separate management requirement, so candidates should organize Business and Law preparation independently from C-17 technical review.
