What Does BC-A,b(sm) Mean?

The classification name looks like somebody lost a fight with a keyboard, but it makes more sense when you break it apart.

Combine the two and you get BC-A,b(sm), allowing qualifying residential construction plus small-commercial construction under one contractor classification.

Review the Tennessee Contractor Classification Outline before registering for an exam.

How Is BC-A,b(sm) Different From Other Tennessee Building Licenses?

Tennessee offers several building classifications, and choosing the wrong one can mean taking an exam that does not match your business plans.

Tennessee also offers the full BC classification for residential, commercial, and industrial building work.

When Is a Tennessee Contractor License Required?

Tennessee generally requires a contractor license before contracting for projects of $25,000 or more.

Contracting can include:

• Bidding on the project.
• Offering to perform the work.
• Negotiating the contract price.
• Contracting directly with the owner.
• Acting as a construction manager or consultant on qualifying projects.

The important word is before.

You do not want to sign a $900,000 contract and then decide that Tuesday afternoon would be a nice time to investigate contractor licensing.

Start with the Tennessee Contractor Licensing page.

Step 1: Choose the Business That Will Hold the License

Tennessee contractor licenses are issued to a specific business entity.

That may be:

• A sole proprietor.
• A partnership.
• A corporation.
• An LLC.

The business name needs to remain consistent throughout the licensing process.

Your application, financial documents, surety bond when used, insurance, and Secretary of State records should all identify the correct entity.

Tiny differences in business names can create surprisingly large delays.

Step 2: Select Your Qualifying Agent

The individual who qualifies the business for the contractor classification is called the Qualifying Agent, or QA.

The QA may generally be:

• An owner.
• An officer.
• A full-time employee.
• Another qualifying person permitted under Board rules.

A Power of Attorney form may be required when the QA does not have the ownership relationship required by the Board.

Tennessee also allows the Business and Law exam and trade exam to be taken by different qualifying individuals in certain cases.

Step 3: Build Relevant Construction Experience

Tennessee reviews the applicant's and Qualifying Agent's experience when deciding whether the requested classification and monetary limit are appropriate.

For BC-A,b(sm), useful experience includes both residential and small-commercial construction.

• Estimating.
• Plan reading.
• Site preparation.
• Footings and foundations.
• Concrete.
• Masonry.
• Carpentry and framing.
• Structural steel.
• Roofing and insulation.
• Doors, windows, and stairs.
• Interior and exterior finishes.
• Scheduling.
• Subcontractor coordination.
• Code compliance.
• Jobsite safety.

The Board has historically preferred approximately three years of relevant experience, but the strength and type of experience matter too.

A contractor requesting a large monetary limit should be prepared to demonstrate experience that makes sense for projects of that size.

Step 4: Register for the Correct Trade Exam

Tennessee changed contractor examination providers in 2026.

Beginning July 1, 2026, new exam scheduling moved to Prov.

The examination you want is:

Be careful not to accidentally register for:

• BC-A Residential only.
• BC-b(sm) Small Commercial only.
• BC-A,B Residential / Commercial.
• BC Residential / Commercial / Industrial.

They are different examinations tied to different classification scopes.

Step 5: Understand the BC-A,b(sm) Exam

The current Prov BC-A,b(sm) Combined Residential / Small Commercial Contractor exam contains:

• 100 questions.
• 2-hour time limit.
• 73% passing score.
• $53 examination fee.
• Open-book format.

Two hours for 100 questions gives you an average of only 72 seconds per question.

That makes this a very different kind of open-book exam.

You have access to reference books, but you absolutely do not have time to begin every question by reading three chapters and hoping the answer waves at you.

Step 6: Know the Current Exam Breakdown

The current Prov outline divides the 100 questions across the following areas:

Estimating, carpentry, concrete, roofing, code, OSHA, masonry, and structural steel are especially important because together they make up a large part of the test.

Step 7: Get the Correct Exam References

Prov currently lists five main references for the BC-A,b(sm) examination:

• International Building Code, 2021.
• International Residential Code, 2021.
• Study Guide for Commercial Building Contractor, 2024.
• OSHA 29 CFR 1926.
• Residential Home Builder Study Guide.

During the testing-provider transition, Prov also allows certain previously approved PSI reference materials through January 1, 2027.

After that date, candidates should expect to use the references approved under Prov's current list.

You can review the Tennessee BC-A,b(sm) Complete Exam Book Package from 1 Exam Prep.

Step 8: Prepare Your Open-Book References Correctly

Current Prov rules allow candidates to prepare approved books with:

• Highlighting.
• Permanent tabs attached to important pages.

Current rules prohibit:

• Handwritten notes.
• Moveable tabs.
• Post-it notes.
• Photocopied pages inserted into books.
• Photocopied reference books.
• Unauthorized exam-prep guides in the testing room.
• Practice examinations in the testing room.

Prov currently permits a simple four-function calculator, and a basic calculator is also available within the testing system.

Candidates who want the exam references prepared in advance can review the Tennessee BC-A,b(sm) Highlighted & Tabbed Book Package.

Step 9: Practice Residential and Commercial Code Navigation

The combined exam requires you to move between residential and commercial references quickly.

Practice finding residential topics such as:

• Building planning.
• Foundations.
• Floor construction.
• Wall construction.
• Roof and ceiling construction.
• Stairways.
• Energy-related provisions.
• Weather protection.

Then practice commercial topics involving:

• Occupancy classifications.
• Construction types.
• Means of egress.
• Fire-resistance requirements.
• Accessibility concepts.
• Structural systems.
• Commercial building materials.

Your first job is deciding which book probably contains the answer.

Opening the wrong book with only 72 seconds available is a surprisingly efficient way to make a simple question difficult.

Step 10: Practice Estimating and Plan Reading

Estimating and plan reading account for 12 current exam questions.

Practice:

• Reading floor plans.
• Reading elevations.
• Understanding sections and details.
• Calculating square footage.
• Calculating cubic yards.
• Estimating concrete.
• Estimating framing material.
• Estimating roofing.
• Interpreting dimensions and scales.

Estimating is useful on the exam and even more useful when actual customers expect your price to have some relationship with reality.

Step 11: Study OSHA Safety

OSHA safety currently accounts for 8 questions.

Review:

• Fall protection.
• Scaffolds.
• Ladders.
• Excavation.
• Personal protective equipment.
• Power tools.
• Material handling.
• General jobsite hazards.

Eight questions can make a meaningful difference when 73% is the passing line.

Step 12: Pass Tennessee Business and Law

New Tennessee contractor applicants also generally need the Tennessee Contractor Business and Law examination.

The current Prov program lists:

• 50 questions.
• 73% passing standard.
• $53 examination fee.
• Open-book format.

Prov's current online Tennessee testing page shows a 2.5-hour time allowance for Business and Law, while the June 15, 2026 PDF Candidate Information Bulletin still displays 2 hours.

Subjects include:

• Business organization.
• Licensing.
• Estimating and bidding.
• Contracts.
• Project management.
• Risk management.
• OSHA safety.
• Financial management.
• Labor law.
• Tax law.
• Lien law.

The current reference is the Tennessee edition of the NASCLA Contractors Guide to Business, Law and Project Management, 4th Edition.

Review the Tennessee NASCLA Business and Law Guide from 1 Exam Prep.

Step 13: Use Timed Practice Exams

Two hours for 100 trade questions means pacing needs to be part of your preparation.

1. Study one subject.
2. Answer practice questions without a timer.
3. Review every incorrect answer.
4. Find the supporting rule in the correct reference.
5. Repeat the same subject under a timer.
6. Practice switching between books.
7. Complete full-length timed sessions.

Keep track of slow answers too.

A question you answer correctly in six minutes may still be an exam-day problem when your average budget is barely over one minute.

For structured study, review the Tennessee BC-A,b(sm) Online Exam Prep Course.

Step 14: Understand Your Tennessee Monetary Limit

Tennessee contractor licenses are issued with a monetary limit.

This limit controls the maximum amount of an individual contract or project that the contractor may undertake, subject to Tennessee's rules.

When the traditional financial-statement method is used, Tennessee generally evaluates:

• Working capital.
• Net worth.
• Experience.
• Classification.
• Project history.

In many cases, the monetary limit is based on ten times the lesser of working capital or net worth, together with the Board's review of experience and classification.

The BC-b(sm) small-commercial classification itself cannot exceed $1,500,000.

Step 15: Choose a Financial Statement or the New Surety Bond Option

Tennessee updated its contractor financial rules for 2026.

Under the current financial-statement route, an initial application requesting a monetary limit of $3 million or less generally requires a CPA-prepared reviewed or audited financial statement.

Beginning July 1, 2026, Tennessee also allows a qualifying continuous Contractors' Surety Bond to be used instead of the financial statement when all requirements are satisfied.

The bond must equal at least 50% of the requested monetary limit.

Examples from the current Board guide include:

• $500,000 requested limit: $250,000 minimum surety bond.
• $1,500,000 requested limit: $750,000 minimum surety bond.

If the qualifying surety bond stops being effective and a compliant financial statement has not replaced it, the contractor license can become invalid.

Review the current Board financial instructions carefully before choosing between these options.

Step 16: Obtain General Liability Insurance

Tennessee contractors must maintain general liability insurance.

The minimum coverage depends on the license's monetary limit.

• Up to $500,000 monetary limit: at least $100,000 liability coverage.
• $500,001 through $1,500,000: at least $500,000 liability coverage.
• Above $1,500,000: at least $1,000,000 liability coverage.

Make sure the insured name matches the exact business name being licensed.

Step 17: Handle Workers' Compensation Requirements

Workers' compensation requirements can apply depending on the business, employees, ownership structure, and work being performed.

Applicants must provide the appropriate coverage or qualifying exemption documentation when applicable.

Because BC-A,b(sm) includes commercial construction authority, contractors should pay special attention to Tennessee rules affecting construction service providers on commercial projects.

Do not assume an exemption that worked on one project automatically solves every workers' compensation issue on another.

Step 18: Submit the Tennessee Contractor Application

After completing the testing and gathering your licensing documents, submit your contractor application to the Tennessee Board for Licensing Contractors.

Tennessee currently uses the CORE online licensing system.

The current initial contractor application fee is $250.

Be prepared to provide:

• Business entity information.
• Qualifying Agent information.
• Exam score reports.
• Experience information.
• Professional reference information.
• Financial statement or qualifying surety bond documentation.
• General liability insurance.
• Workers' compensation or exemption documentation.
• Secretary of State registration when applicable.
• Required disclosures and signatures.

Passing the examination does not itself issue the license.

The Board must still review and approve the application.

What Happens If You Fail an Exam?

Current Prov rules allow unsuccessful candidates to retake a Tennessee contractor examination as many times as necessary.

There is currently no mandatory waiting period between attempts.

Each retake costs another $53.

Candidates who fail at least twice and score within ten points of the 73% passing standard may also qualify for an exam review under current Prov rules.

The best response to a failed attempt is not simply another attempt. Use the diagnostic information to find the subjects that need work.

How Long Is the Tennessee Contractor License Valid?

Tennessee contractor licenses are generally issued for a two-year period.

The current renewal fee is $200.

Renewal may require:

• Updated financial information or qualifying surety bond.
• General liability insurance.
• Workers' compensation coverage or exemption documentation.
• Active Secretary of State status when applicable.
• Residential Continuing Education when required.

Tennessee recommends submitting the renewal before expiration rather than testing how exciting contractor life becomes with an expired license.

BC-A,b(sm) Requires Residential Continuing Education

Because BC-A,b(sm) includes the BC-A residential classification, certain licensees must complete Residential Continuing Education.

Contractors first licensed after January 1, 2009 with BC-A,b(sm) currently need 8 hours of Board-approved Residential Continuing Education for each two-year renewal cycle.

The Qualifying Agent completes the RCE on behalf of the licensed business.

Review the Tennessee Residential Continuing Education Provider List before enrolling in a course.

Helpful Tennessee BC-A,b(sm) Resources

Frequently Asked Questions

Here are common questions about Tennessee's BC-A,b(sm) Combined Residential / Small Commercial Contractor classification.

Key Takeaways

• BC-A,b(sm) combines residential and small-commercial construction. The residential side covers qualifying one- through four-family buildings up to three stories, while the small-commercial classification is capped at $1.5 million.
• The current Prov trade exam has 100 questions and only two hours. Candidates need at least 73% to pass, making fast open-book navigation especially important.
• New applicants normally need Business and Law too. It is a separate examination covering licensing, contracts, estimating, taxes, liens, safety, financial management, and contractor business responsibilities.
• Passing the exams is only part of licensing. Tennessee also reviews experience, financial qualification, monetary limits, insurance, business records, and Qualifying Agent information.
• BC-A,b(sm) has an ongoing residential education requirement. Qualifying licenses first issued after January 1, 2009 currently need eight hours of approved RCE for each two-year renewal.

Final Thoughts Before You Start

Tennessee's BC-A,b(sm) classification can be a smart choice for contractors who want more flexibility than a residential-only license but do not need the full unrestricted commercial classification.

It gives you access to qualifying residential construction and small-commercial projects under one classification. That can work well for contractors building homes, remodeling residential properties, constructing smaller commercial buildings, or developing a business that serves both markets.

The first decision is making sure the classification matches your actual plans. BC-A,b(sm) is not the same as BC-A, BC-b(sm), BC-A,B, or the full BC classification. Pick the exam based on the work you want to perform several years from now, not just the first project currently sitting on your desk.

Once you know the classification is right, get the business side organized. Choose the entity that will hold the license, identify the Qualifying Agent, document your experience, and make sure your business records are consistent.

Then focus on the exams.

The BC-A,b(sm) trade examination deserves serious preparation because the current test gives you only two hours for 100 questions. That is roughly 72 seconds per question. An open-book format will not save you if every lookup takes three minutes.

Learn your books. Know when a question belongs in the IBC, when it belongs in the IRC, when OSHA is the right source, and when one of the contractor study references is more useful. Highlight and permanently tab the references according to Prov's current rules, then practice with the books exactly the way you expect to use them during the exam.

Do not forget Business and Law. Contractors spend plenty of time thinking about framing, concrete, roofs, and schedules, but contracts, financial management, lien rules, taxes, licensing, and risk management can create problems much larger than a crooked wall.

After testing, keep your attention on the licensing application. Your financial qualification determines your monetary limit, the BC-b(sm) portion cannot exceed the small-commercial classification cap, and Tennessee now offers both traditional financial-statement qualification and a newer qualifying surety bond option.

Once the license is issued, keep your insurance current, stay within your classification and monetary limit, complete the required Residential Continuing Education when applicable, and renew on time.

When you are ready to organize your preparation, explore the Tennessee BC-A,b(sm) Combined Residential / Small Commercial Contractor resources from 1 Exam Prep.
