Hawaii Cabinet, Millwork, And Carpentry Remodeling And Repairs Contractor (C-5) Exam - Online Practice Questions

Prepare for the Hawaii Cabinet, Millwork, and Carpentry Remodeling and Repairs Contractor (C-5) examination with online practice questions designed to reinforce plan reading, estimating, rough carpentry, stairs, cabinetry, millwork, siding, drywall, windows, doors, finish carpentry, remodeling, repair work, tools, and OSHA construction safety.

This online practice-question product includes 3 months access, giving candidates time to review carpentry and remodeling concepts, strengthen construction calculations, identify weaker subjects, reinforce safety knowledge, and build a consistent study routine before taking the official Hawaii C-5 contractor examination.

The Hawaii C-5 Cabinet, Millwork, and Carpentry Remodeling and Repairs Contractor classification covers a broad range of finish carpentry and remodeling work. The scope includes installing cabinets, cases, sashes, doors, trim, and nonbearing partitions that become a permanent part of a structure, along with remodeling and repairs to existing buildings and structures.

The classification also includes installation of window shutters, garage doors, bifold doors, shutter doors, and manufactured siding. An important limitation is that C-5 work does not include changes or additions to basic structural components such as foundations, beams, rafters, joists, or other load-bearing members or sections.

The official C-5 trade examination is administered by PSI Services LLC for the Hawaii Department of Commerce and Consumer Affairs, Professional and Vocational Licensing Division. Applicants must receive approval from the Hawaii Contractors License Board before registering for the examination.

The current Hawaii C-5 examination contains 40 questions. Candidates receive 120 minutes, or 2 hours, to complete the examination and must achieve a minimum passing score of 75%.

This examination is CLOSED book. The technical references associated with the examination are not allowed in the testing center. Candidates should therefore use the study books during preparation to develop strong working knowledge of carpentry, cabinetry, millwork, drywall, siding, doors, windows, estimating, code concepts, and construction safety.

Exam Details

The Hawaii C-5 Cabinet, Millwork, and Carpentry Remodeling and Repairs Contractor examination contains 40 questions. Candidates receive 120 minutes to complete the test, and the minimum passing score is 75%.

The official examination content outline includes:

• Plan Reading and Estimating: 4 questions
• Rough Carpentry Including Stairs: 8 questions
• Cabinetry and Millwork: 12 questions
• Associated Trades Including Siding, Drywall and Windows and Doors: 12 questions
• Safety OSHA: 4 questions

Cabinetry and Millwork is one of the two largest examination categories with 12 questions. Candidates should be prepared for cabinet components, materials, joinery, layout, hardware, installation, trim, finish carpentry, and millwork practices.

Associated Trades also contains 12 questions and includes siding, drywall, windows, and doors. This category reflects the broad remodeling and repair responsibilities of the C-5 contractor.

Rough Carpentry Including Stairs contributes 8 questions. Candidates should understand framing terminology, wall components, stair construction, openings, layout, fastening, and the difference between work allowed under C-5 and work involving structural components outside the classification.

Plan Reading and Estimating and Safety OSHA each contribute 4 questions. Because the test contains only 40 questions, every content area can have a meaningful effect on the final score.

Closed Book Test

This examination is CLOSED book.

The reference materials listed for the Hawaii C-5 examination are used for preparation but are not allowed in the examination center.

Closed-book preparation should emphasize understanding and recall. Candidates should be able to recognize common cabinet and carpentry components, select suitable installation methods, understand construction terminology, interpret plans, perform basic calculations, and identify safe work practices without relying on immediate reference lookup.

A useful study method is to review a topic in the appropriate reference, answer practice questions from memory, and then return to the book to investigate any missed questions. This approach helps turn passive reading into knowledge that can be recalled during the examination.

Candidates receive 120 minutes for 40 questions, which provides an average of approximately 3 minutes per question. Familiarity with the core trade subjects can preserve more time for plan-reading and calculation questions.

Licensing Steps

1. Confirm that the C-5 classification matches your intended work. Hawaii C-5 covers cabinetry, millwork, finish carpentry, remodeling, repairs, nonbearing partitions, siding, windows, doors, and related work within the classification scope.
2. Complete the appropriate Hawaii contractor license application. Applications are submitted through the Hawaii Department of Commerce and Consumer Affairs, Professional and Vocational Licensing Division.
3. Document qualifying experience. Applicants must demonstrate experience that satisfies the Contractors License Board requirements for the classification sought.
4. Receive Contractors License Board approval. Applicants must be approved before registering for the trade examination.
5. Register with PSI after approval. Eligible applicants receive examination registration information following Board approval.
6. Prepare for the C-5 examination. Study cabinetry, millwork, carpentry, stairs, siding, drywall, windows, doors, plan reading, estimating, and OSHA safety.
7. Pass the C-5 trade examination. The current test contains 40 questions, allows 120 minutes, and requires a 75% passing score.
8. Complete the applicable Business and Law examination. New Hawaii contractor applicants must also satisfy the Business and Law examination requirement when applicable.
9. Complete remaining licensing requirements. All applicable experience, financial, insurance, business entity, application, and Board requirements must be satisfied before a contractor license is issued.

State Requirements

Hawaii contractor licenses are regulated by the Contractors License Board within the Department of Commerce and Consumer Affairs, Professional and Vocational Licensing Division.

The C-5 classification authorizes work involving cabinets, cases, sashes, doors, trim, and nonbearing partitions that become permanent parts of a structure. It also permits remodeling and repair work within the limits of the classification.

The scope includes installation of window shutters, garage doors, bifold doors, shutter doors, and manufactured siding.

A critical limitation is that C-5 work does not include changes or additions to a building's basic structural components, including foundations, beams, rafters, joists, and other load-bearing members or sections.

This distinction should receive attention during exam preparation. A contractor may be skilled in many forms of carpentry, but licensing scope determines which work may be performed under the C-5 classification.

Applicants must receive Board approval before registering for the examination through PSI. Hawaii contractor examination eligibility is valid for six months after approval, and candidates must complete the required examination process during that eligibility period.

Passing the C-5 trade examination by itself does not issue a Hawaii contractor license. Applicants must also satisfy the applicable Business and Law examination, experience, insurance, financial, entity, and other licensing requirements.

Test Information and Study Materials

A strong Hawaii C-5 study plan should begin with Cabinetry and Millwork and Associated Trades. Together, these two categories account for 24 of the 40 examination questions.

Cabinetry and Millwork preparation should include cabinet terminology, face frames, frameless construction, doors, drawers, shelving, backs, panels, rails, stiles, hardware, fasteners, and installation techniques.

Candidates should understand common woodworking joints and how different joints are used in cabinets, cases, drawers, trim, and other millwork applications.

Review wood and manufactured panel products. Cabinet work can involve solid lumber, plywood, particleboard, medium-density fiberboard, veneers, laminates, and other materials. Understanding basic characteristics can help candidates select appropriate methods of cutting, fastening, and finishing.

Cabinet installation requires careful layout. Candidates should be comfortable with level, plumb, square, alignment, fastening, wall conditions, fillers, scribing, and coordination with countertops and appliances.

Finish carpentry should include trim and molding. Review baseboards, casing, crown molding, chair rail, jambs, reveals, joints, corners, and techniques used to produce clean finished installations.

The Finish Carpenter's Manual can be useful for strengthening knowledge of fitting, measuring, cutting, fastening, and installing finish components.

Associated Trades Including Siding, Drywall and Windows and Doors also represents 12 questions. Candidates should prepare broadly rather than treating this as a single subject.

For drywall, review gypsum board types, panel orientation, fastening, joints, corners, finishing, nonbearing partitions, and common installation practices.

Use the Gypsum Construction Handbook to understand how board, framing, fasteners, joint treatment, accessories, and finishes work together in a complete wall or ceiling assembly.

Windows and doors are important remodeling components. Review rough openings, jambs, frames, sashes, installation, shimming, fastening, flashing, weather protection, hardware, and operation.

Door preparation should include interior doors, exterior doors, bifold doors, garage doors, and shutter-type doors included within the C-5 scope.

Review how doors are kept plumb, level, and square during installation. Improperly installed frames can create problems with operation, clearance, latching, and finished appearance.

Siding is another subject within the associated trades section. Hawaii's C-5 scope includes manufactured siding installation as part of the classification.

Study layout, fastening, expansion considerations, flashing, weather protection, trim, corners, openings, and proper sequencing with windows and doors.

Rough Carpentry Including Stairs accounts for 8 questions. Review framing terminology, studs, plates, blocking, headers, openings, fasteners, stair components, and general carpentry layout.

Pay particular attention to the difference between nonstructural remodeling work and changes involving load-bearing components. The C-5 classification does not authorize changes or additions to foundations, beams, rafters, joists, or other load-bearing portions of a structure.

For stairs, candidates should understand common components such as stringers, treads, risers, landings, handrails, guards, and related dimensions and layout concepts.

Practice basic stair calculations and terminology. Closed-book testing rewards candidates who understand how stair components relate to one another rather than simply remembering isolated definitions.

Plan Reading and Estimating contributes 4 questions. Practice reading floor plans, elevations, sections, details, schedules, dimensions, symbols, and construction notes.

Estimating should include linear measurements, square footage, material quantities, waste considerations, and dimensions relevant to cabinets, trim, drywall, siding, and other C-5 work.

For cabinetry, estimating may require calculating cabinet runs, countertop dimensions, trim quantities, shelving, or sheet materials. For drywall and siding, candidates should be comfortable determining surface area and adjusting quantities for openings and waste where appropriate.

Always identify the units before calculating. Mixing feet, inches, square feet, and linear feet can create avoidable mistakes.

Safety OSHA accounts for 4 questions. Use 29 CFR Part 1926 to review construction safety requirements relevant to carpentry and remodeling operations.

Study ladders and scaffolds, since remodeling contractors commonly perform work at elevated locations. Candidates should recognize unsafe setup, access, loading, and use conditions.

Power tool safety is also important. Carpentry and cabinet work frequently involve saws, routers, drills, nailers, sanders, and other equipment that can cause serious injury if used incorrectly.

Review guarding, personal protective equipment, electrical safety, housekeeping, material handling, and safe operation of common construction tools.

Remodeling jobs can also create unique hazards because work is performed inside existing structures. Workers may encounter occupied areas, concealed utilities, existing finishes, restricted access, and changing site conditions.

The International Building Code, 2018 should be used to reinforce broad building requirements related to C-5 work. Focus on concepts relevant to partitions, interior finishes, doors, openings, egress, and remodeling conditions.

Because this is a closed-book examination, gradually reduce your dependence on the references as preparation progresses. Read and study first, then work questions without opening the book.

When a practice question is missed, identify whether the issue involved terminology, measurement, installation sequence, code knowledge, tool selection, materials, or safety.

Organize missed questions by topic. If cabinetry is difficult, return to cabinet components and joinery. If associated trades produce errors, separate the review into drywall, siding, doors, and windows.

Use mixed-topic practice as exam day approaches. The official test may move from cabinetry to stair construction, then drywall, estimating, siding, windows, or OSHA safety.

The included 3 months access gives candidates time to progress from individual-topic study into focused practice, correction of weaker areas, mixed-question review, and exam-oriented preparation.
