Mississippi Major Contractor Classification • MSBOC • PSI • 80 Questions • 180 Minutes • 70% Passing • 2021 IBC
Ready to earn your Mississippi Building Construction Contractor license? This complete exam prep guide explains the official MSBOC licensing process, the PSI Building Construction trade examination, approved reference books, construction safety, estimating, plan reading, concrete, masonry, steel, carpentry, roofing, and the related exam prep products available from Contractor Exam Preps.
Mississippi Building Construction is a major contractor license classification regulated by the Mississippi State Board of Contractors, also called MSBOC.
This classification involves the construction of commercial buildings, residential structures, and other buildings within the Board's defined scope.
It can also cover additions, alterations, conversions, expansions, reconstruction, renovation, and rehabilitation of existing structures.
Building projects can involve landscaping, earthwork, parking areas, driveways, sidewalks, and related work within the classification's permitted scope.
Unlike a narrow trade license, the Building Construction classification brings several construction disciplines together.
A building contractor needs to understand concrete, framing, roofing, structural steel, masonry, plans, materials, building codes, safety, and project management.
That sounds like a lot because it is!
Running a building project is a little like conducting an orchestra.
Except the instruments are excavators, saws, concrete trucks, and subcontractors, and someone always wants to know where the tape measure went.
The Mississippi Building Construction licensing process tests whether a candidate understands the construction knowledge and responsibilities needed to work under this classification.
Under the current published PSI Candidate Information Bulletin, candidates pursuing the state-specific Building Construction examination face 80 scored questions.
The exam allows three hours, or 180 minutes.
The passing score is 70%.
That means candidates must answer at least 56 of the 80 scored questions correctly.
The examination is administered by PSI after MSBOC approves the applicant's eligibility.
Mississippi does not allow applicants to skip directly to scheduling the examination without the appropriate Board review.
The qualifying party must first be identified and the application must be processed.
Once the Board determines eligibility, PSI sends examination registration information.
The state-specific Building Construction examination is open book.
That allows candidates to bring approved construction reference books into the examination room.
However, the open-book rules are strict.
Only authorized references can be used.
Reference materials can be highlighted, underlined, and permanently tabbed before testing, subject to PSI rules.
Temporary removable tabs, loose notes, inserted pages, and unauthorized reference material are prohibited.
Candidates cannot write in their books during the examination.
The goal is not to carry as many books as possible.
It is to understand which book contains the answer and how to find that information quickly.
With 80 questions in 180 minutes, the average time available is approximately 2.25 minutes per question.
Every minute spent looking in the wrong book makes the remaining questions more difficult to manage.
The Mississippi Building Construction trade examination contains 11 published subject categories.
The largest category is General Code, Plan Reading and Estimating, with 15 questions.
This category includes building-code requirements, construction drawings, specifications, estimates, quantities, and general construction knowledge.
Contractors need to understand how to interpret plans before work begins.
A building drawing may show dimensions, foundations, walls, columns, roof structures, doors, windows, and important construction details.
Specifications describe the materials and installation standards associated with the project.
Estimating helps contractors determine quantities, labor requirements, material needs, and project costs.
Incorrect estimates can create expensive problems even when the construction work itself is good.
The second-largest category is Concrete, with 12 questions.
Concrete construction includes materials, mixing, placement, reinforcement, curing, and quality control.
Building contractors should understand how concrete strength, forms, reinforcing steel, and construction conditions affect structural performance.
The exam also covers post-tensioning concepts.
These systems require knowledge of specialized materials and construction procedures.
Metals is the third-largest category, with 10 questions.
Study structural steel, steel joists, joist girders, metal connections, reinforcing materials, and safe erection practices.
Steel components carry building loads and need proper handling and installation.
Safety accounts for eight questions.
The approved OSHA construction reference covers a wide range of jobsite hazards.
These include fall protection, ladders, scaffolding, excavation, tools, equipment, personal protective equipment, and steel erection.
Safety preparation matters on the exam and on actual construction projects.
Carpentry includes seven questions.
This section can involve building layout, framing, wood construction, roof framing, materials, and installation techniques.
Thermal and Moisture Protection also includes seven questions.
Roofing systems, insulation, waterproofing, vapor control, building-envelope protection, and moisture-resistant construction practices can appear in this section.
Site Work includes six questions.
These subjects involve clearing, grading, excavation, site preparation, utility protection, and earthwork.
Masonry also includes six questions.
Study brick, block, stone, mortar, reinforcement, and masonry construction methods.
Doors and Windows includes three questions.
This category includes openings, installation details, frames, and related construction requirements.
Finishes includes three questions.
Review interior and exterior finish systems and general finishing requirements.
Mississippi One Call includes three questions.
This subject involves underground utility notification and excavation responsibilities.
Mississippi's excavation regulations are especially important because digging without proper coordination can damage underground utilities and create serious hazards.
All 11 categories total the 80 scored trade questions.
The current official study foundation includes the 2021 International Building Code.
The 2021 IBC is the specifically listed building-code edition for the state-specific examination.
It covers occupancy classifications, construction types, structural requirements, fire protection, means of egress, accessibility, building materials, and other construction subjects.
Candidates should not assume that an older or newer IBC edition is automatically acceptable for code questions.
The PSI bulletin states that code questions use the listed code edition.
Other examination references include OSHA 29 CFR Part 1926, steel-joist technical guidance, carpentry, concrete, excavation, roofing estimating, Mississippi utility protection regulations, post-tensioning, masonry, and reinforcing steel.
The full approved reference list contains 11 trade references.
Those books support the technical knowledge required across the Building Construction classification.
Because the reference collection is large, candidates should begin organizing it early.
Contractor Exam Preps offers the Mississippi PSI Building Construction Course.
This online course is designed for candidates preparing for the state-specific PSI Building Construction examination.
It includes a self-paced study format, exam strategies, reference-book highlighting and tabbing guidance, printable practice questions, and one year of course access.
The course can be accessed on supported mobile devices, including Android and iOS.
That makes it useful for contractors balancing study with their normal work schedule.
Contractor Exam Preps also offers the Mississippi Building Construction Contractor Book Rental Package.
This package brings together construction references for the trade and business examinations.
It includes professionally highlighted and permanently tabbed rental books, along with related online preparation.
The package uses a refundable book deposit, subject to the stated rental period and return conditions.
It is important to confirm the actual package description before ordering because rental terms, course access, and additional services differ among products.
The Mississippi Building Construction Ultimate Exam Prep Rental Package combines trade and business reference books, online study access, and Application Service.
Its product description identifies prepared, highlighted, and tabbed rental references to support open-book testing.
For contractors who want additional business startup assistance, Contractor Exam Preps offers the All-Inclusive Mississippi Building Construction Contractor Package.
This package combines construction examination preparation with contractor application assistance and business formation services.
It also includes EIN filing support and contractor compliance guidance, subject to the published product conditions.
One very important detail concerns the edition of the reference books.
Some Contractor Exam Preps package descriptions include newer editions of concrete, masonry, or reinforcing-steel books than the editions shown on the current PSI Building Construction reference list.
For example, PSI currently lists the 15th or 16th edition of Design and Control of Concrete Mixtures.
Some store packages advertise the 17th edition.
PSI lists Modern Masonry, 8th Edition.
Some package listings advertise the 10th edition.
PSI also lists Placing Reinforcing Bars, 9th Edition, while certain packages advertise the 10th.
For non-code reference books, the bulletin explains that older or newer editions may be used at the candidate's own risk.
However, differences between editions can lead to conflicting answers.
The specifically listed edition of the International Building Code is mandatory for code questions.
Before buying or renting a book package, compare the books with the current PSI bulletin.
Do not assume every title and edition automatically matches the examination reference list.
Mississippi also gives eligible Building Construction applicants another trade-exam option.
Candidates may choose the NASCLA Accredited Examination for Commercial General Building Contractors instead of the Mississippi-specific Building Construction trade examination.
The NASCLA exam is a separate examination.
It has a different question count, time limit, content blueprint, and reference library.
The PSI bulletin lists the NASCLA Accredited Commercial General Building examination as 115 questions with 330 minutes allowed and a minimum passing score of 81.
This is different from the Mississippi-specific Building Construction exam of 80 questions in 180 minutes.
The choice between the two routes depends on the applicant's plans and the requirements accepted by the licensing Board.
Contractors who may seek licenses in several participating states sometimes consider the NASCLA accredited exam.
However, passing NASCLA does not automatically issue a Mississippi contractor license.
Applicants still need MSBOC approval and must meet the applicable state licensing requirements.
The Mississippi Law and Business Management examination is also normally mandatory.
It contains 50 scored questions.
Candidates are allowed two hours.
The passing requirement is 70%, or 35 correct scored answers.
The approved Mississippi business reference is the NASCLA Contractor's Guide to Business, Law and Project Management, Mississippi, 6th Edition.
This exam covers licensing, estimating, bidding, lien law, financial management, taxes, labor laws, contracts, business organization, risk management, safety, and project management.
The Mississippi NASCLA Contractor's Guide, 6th Edition is available from Contractor Exam Preps.
Applicants should plan separate study time for the business examination because technical construction knowledge does not automatically cover legal and financial responsibilities.
A contractor may be excellent at building walls and pouring foundations but still struggle with a poorly written contract or an inaccurate estimate.
The state licensing process requires attention to both sides of the business.
MSBOC reviews business applications, qualifying-party information, and the documents required for the chosen license category.
Applicants must receive examination eligibility before scheduling with PSI.
The PSI bulletin currently states that new applicants have six months from the date of eligibility to complete the required examinations.
Retesting is available during that eligibility period under the current testing rules.
If the candidate does not pass the required examinations within the eligibility window, a new application may be necessary.
After passing the examinations and meeting all other requirements, MSBOC reviews the application for license approval.
Contractors should also understand the difference between commercial Building Construction and Mississippi's separate Residential Builder classification.
The Building Construction classification is a major commercial classification that includes the scope identified by MSBOC.
The Residential Builder classification is a separate licensing path with different examination requirements.
Applicants should confirm the proper license based on planned work and project types.
Mississippi contractor licenses generally require annual renewal.
Contractors must also maintain applicable financial, insurance, employment, registration, tax, and compliance requirements.
The goal of this Mississippi Building Construction Contractor Exam Prep guide is to help candidates understand the licensing process before they begin studying.
The sections below include the official exam blueprint, licensing requirements, approved references, a building-construction illustration, open-book study strategies, exam comparisons, a six-week plan, related Contractor Exam Preps products, interactive FAQs, a 1ExamPrep YouTube video, and an extended conclusion.
Important Mississippi Building Construction 2026 Update: The PSI state-specific Building Construction trade examination contains 80 scored questions, allows 180 minutes, and requires 70% passing, or 56 correct answers. The exam includes 11 technical categories. The three largest are General Code, Plan Reading and Estimating with 15 questions, Concrete with 12, and Metals with 10. The examination is open book with 11 approved trade references, including the 2021 International Building Code. Mississippi also accepts the separate NASCLA Accredited Commercial General Building Contractor examination as an alternative trade-exam route. Candidates must distinguish the two tests. The Mississippi Law and Business Management exam is separately required. Some store book bundles contain newer non-code editions than those listed by PSI, so confirm reference editions before your appointment.
A Mississippi Building Construction Contractor holds a major contractor classification issued by the Mississippi State Board of Contractors.
The classification covers construction of commercial buildings and single-dwelling or multiple-dwelling residential structures within the Board's defined scope.
It includes construction of new structures and certain work on existing buildings.
That existing-building work can include additions, alterations, conversions, expansions, reconstruction, renovations, and rehabilitation.
The scope may also include related site improvements such as landscaping, earthwork, driveways, sidewalks, and parking areas.
Holding a major classification can permit work in the related specialty classifications identified by MSBOC.
However, contractors should not assume that every separate specialty or regulated system is automatically included.
The Board makes final classification decisions.
Building contractors need knowledge across multiple disciplines because successful projects depend on the relationship between site work, foundations, structural systems, building enclosures, and finishes.
For example, foundation work must support the structure.
Framing and steel components must carry loads.
Roofing and moisture protection help keep water out.
Doors, windows, and finishes must fit the intended design and code requirements.
Contractors must also manage subcontractors, scheduling, material deliveries, budgets, quality control, safety, and inspections.
The Building Construction examination tests construction knowledge needed for this broad responsibility.

The state-specific Building Construction examination is open book and lists 11 technical references.
The current PSI bulletin controls which code edition and reference materials can be brought into the testing center.
| Official Reference | PSI-Listed Edition | Main Study Purpose |
|---|---|---|
| International Building Code | 2021 | Occupancy, construction type, structural systems, fire safety, materials, code compliance, and general building requirements. |
| OSHA Code of Federal Regulations, 29 CFR Part 1926 | Latest Available Amendments or Approved PSI Selections | Construction safety, excavation, scaffolds, fall protection, steel erection, and personal protective equipment. |
| Technical Digest No. 9, Handling and Erection of Steel Joists and Joist Girders | 4th Edition, 2025 | Handling, placement, temporary support, and erection of steel joists and joist girders. |

| Placing Reinforcing Bars, Recommended Practices | 9th Edition, 2011 or Later Printing | Reinforcing-steel placement, bar arrangements, handling, and construction practices. |
| NASCLA Contractor's Guide to Business, Law and Project Management, Mississippi | 6th Edition | Separate Mississippi Law and Business Management examination. |
Trade exam: 11 listed references.
Business and Law: Separate Mississippi NASCLA guide.
Code requirement: The 2021 International Building Code is specifically listed.
Edition differences: Certain store bundles advertise newer concrete, masonry, or reinforcing-steel books than the PSI list.
PSI rule: Older or newer non-code references may be used at the candidate's own risk. The listed code edition controls code questions.
Before buying: Compare the actual package contents and editions with the current PSI bulletin.
An open-book construction examination is easier to manage when candidates know how the reference materials are organized.
For the Mississippi-specific Building Construction exam, candidates have 180 minutes to answer 80 scored questions.
That is about two minutes and 15 seconds per question.
Learning to identify the correct reference is an important skill.
A question about occupancy classification may require the 2021 International Building Code.
A question about fall protection may require OSHA.
A question about a concrete mixture may involve Design and Control of Concrete Mixtures.
A question about reinforcing steel may involve Placing Reinforcing Bars.
A question about underground utility protection may involve Mississippi One Call regulations.
Practice using the book index and table of contents before relying on tabs.
Permanent reference tabs can help with navigation, but they do not replace understanding.
The Mississippi Building Construction major classification covers construction of commercial buildings and single-dwelling or multiple-dwelling residential structures.
The scope also includes specified additions, renovations, alterations, reconstruction, conversions, and rehabilitation of existing structures.
It may include related landscaping, earthwork, parking areas, driveways, sidewalks, and other building-site improvements.
According to MSBOC, holding a major classification permits the related specialty classifications identified within that major category.
However, classification questions are subject to the Board's final decision.
Contractors should confirm whether additional licenses are required for regulated trades or work outside the authorized classification.
Building contractors must also follow local permits, building codes, zoning, inspections, fire-safety requirements, and other applicable regulations.
For example, building a new commercial structure may involve structural drawings, foundation inspections, fire-protection review, accessible routes, and inspections at different stages.
General contractors often coordinate specialists rather than performing every task themselves.
That requires an understanding of schedules, contracts, safety responsibilities, and quality control.
The correct license classification does not eliminate the need for permits or properly qualified subcontractors.
Major classification: Building Construction.
Common projects: Commercial buildings, residential structures, additions, and renovations.
Related activities: Foundations, structural systems, framing, site improvements, roofing, and finishing.
Final scope decision: MSBOC.
Other obligations: Permits, inspections, insurance, and applicable trade requirements.
| License or Exam | Authority | Main Difference |
|---|---|---|
| Building Construction | MSBOC | Major construction classification for commercial and qualifying residential building work. |
| Mississippi Building Construction Trade Exam | PSI | State-specific examination: 80 questions, 180 minutes, 70% passing. |
| NASCLA Accredited Commercial General Building Exam | NASCLA Program | Alternative accepted trade exam: 115 questions, 330 minutes, 81 correct answers required. |
| Residential Builder | MSBOC | Separate residential licensing classification and examination pathway. |
| Carpentry and Framing | MSBOC | Separate tested specialty classification for framing and carpentry work. |
| Concrete | MSBOC | Separate tested specialty classification for concrete construction. |
| Excavation, Grading and Drainage | MSBOC | Separate tested specialty classification covering related site work. |
| Roofing, Sheet Metal and Siding | MSBOC | Separate tested specialty classification focused on building exterior systems. |
| Mississippi Law and Business Management | PSI | Separate mandatory contractor examination with 50 questions and a two-hour limit. |
Important distinction: The Mississippi-specific Building Construction exam and NASCLA accredited trade exam are not the same examination.
MSBOC choice: Eligible Building Construction applicants may use the approved NASCLA alternative.
Business requirement: Mississippi Law and Business Management remains separate.

Use this plan for the Mississippi-specific Building Construction exam. Candidates choosing the NASCLA alternative should follow the separate NASCLA examination blueprint instead.
The Mississippi Building Construction examination can be challenging because it covers many different construction subjects.
A candidate might know framing very well but have less experience with steel joists or post-tensioned concrete.
Another candidate may be strong in concrete but less familiar with estimating or the International Building Code.
The PSI examination tests knowledge across all 11 published subjects.
It includes 80 scored questions and allows three hours.
The passing score is 70%.
That means at least 56 correct answers are required.
Even though the examination is open book, the reference set is large.
Many questions require candidates to identify the correct technical book before locating the information.
The most heavily weighted subjects are General Code, Plan Reading and Estimating, Concrete, and Metals.
Together, those categories represent 37 scored questions.
However, safety, carpentry, roofing, site work, masonry, doors, windows, finishes, and Mississippi One Call can also affect the final result.
The Mississippi PSI Building Construction Course provides self-paced preparation and study guidance.
The Ultimate Rental Package offers organized rental reference books and related application support.
These resources can help candidates prepare, but no book package or course guarantees a passing score.
Consistent study, jobsite knowledge, code familiarity, and timed practice remain important.
Contractor Exam Preps offers multiple products supporting Mississippi Building Construction exam preparation.
Choose based on whether you need only an online course, a rental book set, additional application assistance, or an all-inclusive licensing preparation package.

It is a major contractor classification issued by MSBOC for qualifying building construction projects, including commercial structures and work within the Board's stated scope.
The Mississippi State Board of Contractors, or MSBOC, oversees contractor licensing.

Renewal and Career Planning
Mississippi contractor licenses generally require annual renewal.
Do not assume a single continuing-education rule applies to every major Building Construction license. Confirm requirements for the specific credential with MSBOC.
A Mississippi license does not automatically authorize construction in another state. Check that state's licensing requirements and any applicable reciprocity or NASCLA acceptance rules.

Preparing for the Mississippi Building Construction Contractor examination is an important step for professionals planning to operate under the state's major Building Construction license classification.
The Mississippi State Board of Contractors regulates this classification and determines the types of projects covered by the license.
Building Construction can involve commercial buildings, residential structures, additions, renovations, reconstruction, and other work within the Board's defined scope.
It is a broad classification requiring knowledge of several different construction systems.
A building contractor must understand how a project moves from site preparation to foundations, structural framing, roofing, finishes, inspections, and final completion.
Contractors must also understand plans, estimates, scheduling, materials, jobsite safety, and quality control.
These responsibilities explain why the Mississippi Building Construction examination covers so many subjects.
The state-specific PSI trade examination contains 80 scored questions.
Candidates are given three hours to complete the test.
The passing score is 70%.
This means at least 56 questions must be answered correctly.
The examination is open book, but candidates must follow PSI's rules for approved materials, book editions, tabs, and highlighting.
The current state-specific examination lists 11 technical references.
One of the most important references is the 2021 International Building Code.
This code covers many topics, including occupancy, construction types, building materials, structural provisions, fire protection, safety, and general building requirements.
The other examination references cover OSHA safety, carpentry, concrete, reinforcing steel, steel joists, excavation, roofing, masonry, post-tensioning, and Mississippi underground utility regulations.
Learning the correct reference for each question is a valuable exam skill.
The published PSI blueprint identifies 11 subject categories.
General Code, Plan Reading and Estimating is the largest, with 15 questions.
Concrete follows with 12 questions.
Metals includes 10 questions.
Together, these three topics represent 37 questions, or approximately 46.25% of the state-specific examination.
These subjects deserve special attention during preparation.
However, the remaining categories are also important.
Safety includes eight questions.
Carpentry and Thermal and Moisture Protection each include seven.
Site Work and Masonry each include six.
Doors and Windows, Finishes, and Mississippi One Call each include three.
Successful study should cover the full outline rather than concentrating on a single construction trade.
Contractor Exam Preps offers the Mississippi PSI Building Construction Course.
This self-paced course provides one year of access and includes reference-navigation guidance, highlighting and tabbing recommendations, practice questions, and exam strategies.
It can help candidates organize study time and work through the exam topics more consistently.
Contractor Exam Preps also offers the Mississippi Building Construction Book Rental Package.
This package includes prepared rental references for the trade and business examination process.
Its highlighted and permanently tabbed books can support faster navigation during open-book practice.
The Ultimate Rental Package adds online study access and contractor application assistance.
For candidates who want additional business services, the All-Inclusive Mississippi Building Construction Contractor Package combines exam preparation, licensing support, and selected business formation services.
All product features, current prices, rental deposits, and return conditions should be confirmed on the store listings.
Reference editions are especially important for this examination.
The current PSI bulletin lists specific editions for the approved reference books.
Some Contractor Exam Preps packages advertise newer editions of selected non-code construction references.
PSI allows candidates to use earlier or later non-code editions at their own risk, but the specifically listed code edition controls code questions.
This means applicants should compare their actual books with the official PSI bulletin before testing.
Another important decision concerns the alternative NASCLA examination.
Mississippi accepts the NASCLA Accredited Commercial General Building Contractor examination as an alternative trade-exam route for eligible Building Construction applicants.
However, the NASCLA exam is different from the state-specific 80-question examination.
The NASCLA examination contains 115 questions and allows 330 minutes, with a minimum passing score of 81.
It uses its own reference library and blueprint.
Candidates should choose the route that fits their licensing plans and prepare with materials designed for that specific examination.
Passing NASCLA does not automatically provide a Mississippi contractor license.
The MSBOC licensing application and other requirements still apply.
Mississippi also requires the separate Law and Business Management examination.
This exam contains 50 scored questions and allows two hours.
Its passing score is 70%, or 35 correct answers.
The Mississippi NASCLA Contractor's Guide to Business, Law and Project Management, 6th Edition, is the approved business reference.
Important business subjects include licensing, contracts, estimating, bidding, financial management, taxes, labor laws, safety, risk management, and project administration.
Studying these topics is important because a successful contractor must manage more than construction work.
The company also needs proper business records, reliable estimates, clear contracts, organized projects, and legal compliance.
A practical six-week study schedule can make the preparation process easier.
Start with the PSI bulletin and the 2021 International Building Code.
Then study construction plans and estimating.
Continue with concrete and metals.
Use the following week for safety and carpentry.
Finish the technical review with site work, masonry, roofing, moisture protection, finishes, and Mississippi One Call.
During the final week, complete timed practice examinations with 80 questions and a three-hour limit.
Review missed questions and practice locating the supporting references.
Develop a strategy for questions that take longer than expected.
Time management is important because a three-hour examination can move surprisingly fast.
Before scheduling, confirm that MSBOC has approved your eligibility.
New applicants generally have six months from the eligibility date to complete the required examinations.
After the examinations are passed, MSBOC must still approve the completed licensing application.
Contractors must then maintain the applicable license and renewal requirements.
The purpose of Mississippi Building Construction Contractor exam preparation is not simply to memorize answers.
It is to develop a stronger understanding of building codes, construction systems, estimating, materials, safety, and the responsibilities of a licensed contractor.
By using the current PSI bulletin, approved reference books, consistent practice, and related Contractor Exam Preps resources, candidates can prepare more confidently for their Mississippi Building Construction Contractor licensing examination.
