North Carolina Interior Construction Contractor Exam Book Package

Prepare for the North Carolina Interior Construction Contractor Exam with a complete package containing the two code references allowed inside the examination room and eight additional books used for trade, business, legal, asbestos, plastering, finish carpentry, flooring, and cabinet-construction study.

This package is designed for candidates pursuing the North Carolina S Interior Construction specialty classification through the North Carolina Licensing Board for General Contractors. It combines the approved exam-room codes with supporting publications that address the major technical and administrative areas found on the examination.

The Interior Construction classification covers the installation of acoustical ceiling systems and panels, drywall partitions, lathing and plastering, flooring and finishing, interior recreational surfaces, windows and doors, fixtures, cabinets, and millwork. It also includes asbestos removal and replacement with non-toxic substances.

The exam-room portion of this package includes the North Carolina State Building Code: Building Code 2018 and the North Carolina State Building Code: Administrative Code and Policies, 2018 Edition. These references support questions involving building-code requirements, occupancy and construction provisions, interior assemblies, permits, inspections, and code administration.

The additional books are not allowed inside the testing center, but they support preparation for drywall, gypsum systems, floors, finish carpentry, millwork, cabinets, plastering, asbestos management, respiratory protection, contractor business practices, licensing laws, and liens. Because these publications cannot be consulted during testing, candidates should review them carefully before exam day.

Interior construction combines several finishing trades. Candidates may need to understand wood and metal framing, gypsum-board assemblies, plaster bases, acoustical ceilings, floor systems, doors, windows, trim, cabinets, fixtures, asbestos-related procedures, and project administration. Organized study can help connect these subjects to the code provisions and trade practices addressed by the examination.

An open-book exam still requires preparation. Candidates must recognize the subject of a question, decide whether the answer is likely found in the Building Code or Administrative Code, locate the applicable section, and apply it within the available testing time. Familiarity with both approved codes can make reference searches more efficient.

Exam Details

The North Carolina S Interior Construction Contractor Exam is administered by PSI for the North Carolina Licensing Board for General Contractors. Candidates must receive examination eligibility from the Board before registering and scheduling a testing appointment.

• Classification: S Interior Construction
• Number of questions: 50
• Time allowed: 120 minutes
• Required passing score: 70 percent
• Testing provider: PSI Services
• Exam format: Computer-based contractor licensing examination
• Reference status: Open book with approved references only

The examination contains 15 questions on drywall and plaster, making that the largest content area. Framing involving wood and metal contains seven questions, and finish carpentry and millwork also contains seven questions.

Asbestos removal accounts for six questions. Flooring and finishes account for five questions. Windows and doors account for three questions, while acoustical ceilings account for two questions.

The administrative portion includes two questions on laws and regulations, two questions on permits and inspections, and one lien question. Candidates should study every category because each question contributes to the required passing score.

The examination may include questions developed from the listed references as well as questions based on trade knowledge and general industry practices. Candidates should prepare to recognize materials, evaluate installation procedures, interpret code provisions, identify safety concerns, and apply practical construction knowledge.

A silent, non-printing, non-programmable calculator may be used in the examination center. A magnifying glass may also be provided upon request. All personal items and reference materials remain subject to current testing-center security and inspection procedures.

Open Book Test

The North Carolina Interior Construction Contractor Exam is an open-book test. Only the North Carolina State Building Code: Building Code 2018 and the North Carolina State Building Code: Administrative Code and Policies, 2018 Edition are allowed inside the examination center for this classification.

Candidates are responsible for bringing their own approved references. The testing center does not provide the codes. Complete references are required, and partial code publications are not accepted as exam-room materials.

Building-code references may be printed and spiral bound or hole punched and placed in a three-ring binder. Printed references must be complete and securely bound before they are presented at the testing center.

Approved references may be highlighted, underlined, and indexed before the examination. Permanent tabs may be used when they adhere securely to the pages. Removable tabs such as Post-it flags are not permitted, and notes may not be written on tabs.

References may not contain loose papers, attached notes, inserted study sheets, or other unauthorized materials. Candidates may not write in the books before or during the examination. Testing-center personnel may inspect each reference before allowing it into the exam room.

With 50 questions and 120 minutes, candidates have an average of approximately two minutes and twenty-four seconds per question. Efficient navigation matters. Candidates should learn where the codes address interior finish requirements, gypsum assemblies, occupancy provisions, fire-resistance requirements, doors, windows, accessibility-related construction, permits, inspections, and administrative procedures.

The supporting trade books cannot be used during the exam. Candidates should study drywall, plaster, framing, flooring, finish carpentry, cabinets, asbestos, and respiratory protection in advance so they can answer those questions through prepared knowledge rather than searching for unavailable references.

Licensing Steps

1. Review the classification scope. Confirm that S Interior Construction matches the work the applicant or business intends to perform.
2. Review the current licensing requirements. Examine the application, qualifier, ownership, financial, and organizational requirements established by the North Carolina Licensing Board for General Contractors.
3. Submit the required application or examination request. Provide the Board with the forms and supporting information required for review.
4. Receive examination eligibility. The Board determines whether the candidate is authorized to take the Interior Construction examination.
5. Schedule the examination with PSI. Follow the instructions supplied with the eligibility letter to register, pay the examination fee, and select an appointment.
6. Study the complete package. Review the approved codes and the supporting books that must remain outside the testing center.
7. Prepare the approved codes. Highlight, underline, and add permanent tabs only as permitted under the current examination rules.
8. Take the examination. Bring the required identification and the two approved code references.
9. Complete the licensing process. Passing the examination is one part of qualification. The Board must determine that all applicable requirements have been completed before issuing a license.

The examination eligibility letter is valid for 120 days and permits one examination attempt during that authorization period. Candidates should review their eligibility notice and appointment instructions carefully before selecting a testing date.

State Requirements

The North Carolina Licensing Board for General Contractors regulates the S Interior Construction specialty classification. The classification covers the installation of acoustical ceiling systems and panels, drywall partitions, lathing and plastering, flooring and finishing, interior recreational surfaces, windows and doors, fixtures, cabinets, and millwork.

Drywall partitions within the classification may include load-bearing and non-load-bearing systems. The work can involve wood or metal framing, gypsum panels, fasteners, finishing compounds, accessories, control joints, fire-rated assemblies, and other components required by the plans and applicable code.

The classification also includes asbestos removal and replacement with non-toxic substances. Asbestos-related work may be subject to additional occupational, environmental, training, notification, and project-control requirements beyond the general contractor licensing examination.

Passing the examination does not automatically issue a North Carolina contractor license. Applicants must also satisfy the Board’s application, qualifier, financial, organizational, and license-limitation requirements.

Individual projects may require permits, inspections, building-code compliance, manufacturer instructions, owner specifications, accessibility provisions, fire-resistance requirements, asbestos controls, and occupational-safety procedures. These obligations remain separate from purchasing the book package or passing the examination.

The remaining books in the package are study materials only. They should be reviewed before exam day and must remain outside the testing room.

Test Information and Study Materials

Begin with drywall and plaster because that category contains 15 of the 50 questions. Review gypsum products, panel types, framing, fasteners, joint treatment, finishing levels, control joints, fire-resistant assemblies, sound-control systems, lath, plaster bases, mixing, application, and finishing.

Study wood and metal framing separately. Review spacing, layout, openings, headers, backing, bracing, attachment, partition construction, and coordination with doors, windows, ceilings, cabinets, and finishes.

Use the finish-carpentry and cabinet references to review trim, molding, joints, doors, windows, hardware, casework, built-ins, face frames, drawers, and installation practices. Focus on accurate layout, fit, fastening, alignment, and finished appearance.

Review asbestos management and respiratory protection before testing. Study exposure controls, regulated areas, protective equipment, respirator programs, containment, employee protection, and safe work practices. These references are unavailable during the exam, so preparation should emphasize understanding rather than last-minute lookup.

Use the Building Code to practice finding provisions related to interior finishes, fire-resistance-rated construction, openings, doors, accessibility-related features, materials, and occupancy requirements. Use the Administrative Code for permits, inspections, approvals, and enforcement procedures.

Complete timed lookup exercises with both approved codes. Practice identifying whether a question is technical or administrative, selecting the correct reference, locating the applicable section, and confirming the answer efficiently.

How 1 Exam Prep Helps You Reach Your Goal

1 Exam Prep helps candidates organize the North Carolina Interior Construction examination into manageable technical, code, safety, legal, and business subjects. Structured study guidance can make a broad group of finishing trades easier to review.

Trade-focused preparation connects the books to drywall, plaster, framing, floors, doors, windows, acoustical ceilings, finish carpentry, cabinets, millwork, fixtures, and asbestos-related work. This approach helps students understand how individual topics fit within complete interior construction projects.

Practice-oriented review encourages candidates to apply what they study. Students can work through questions, identify the governing topic, select the correct code when applicable, locate the relevant section, and evaluate the answer under timed conditions.

Reference-navigation practice is especially important because only two codes are allowed inside the exam room. Familiarity with chapters, definitions, tables, indexes, administrative provisions, and common code locations can help candidates use those references more effectively.

1 Exam Prep also supports preparation for subjects found in books that are not permitted during testing. Organized review of drywall, plaster, flooring, carpentry, cabinets, asbestos, business law, licensing, and liens helps candidates build knowledge before exam day.

No book package can guarantee a passing score, licensing approval, or a specific examination result. Consistent study, practical review, and familiarity with the approved references can help candidates approach the examination with stronger preparation and greater confidence.
