Tennessee BC-b Small Commercial Contractor Exam: Complete 2026 Study Guide
You've got the experience. You've done the work. Now you need the license to prove it — and land the commercial jobs that come with it. Tennessee's BC-b Small Commercial Contractor license opens the door to commercial projects valued at $25,000 or more (up to $1,500,000 per project), and it starts with passing the Tennessee BC-b exam. That means two tests: the Trade Exam and the Business and Law Exam. This guide covers everything you need to know about the trade portion — what's on it, what to study, and how to pass it on the first try. Ready to get started? Take our free practice exam and see where you stand today.
Tennessee BC-b Exam Overview
The Tennessee small commercial contractor exam is administered by PSI at testing centers across the state. Here's the quick breakdown:
- Questions: 70 scored questions
- Time limit: 200 minutes (3 hours, 20 minutes)
- Passing score: 73% — that's 52 out of 70 questions correct
- Format: Multiple choice, open book
- Cost: $57 per exam portion (non-refundable)
One important thing: this is an open-book exam, which sounds like a relief — but don't let that fool you. There's no time to flip through an unmarked book looking for an answer. The candidates who pass are the ones who know their references cold and have them tabbed, highlighted, and ready to go. The official exam bulletin has the full candidate information, including the approved reference list.
Topics Covered on the Tennessee BC-b Trade Exam
Nine topic areas make up the exam. Here's how they break down by the number of scored questions — this is where your study time should go:
| Topic | Exam Items |
|---|---|
| General Code, Plan Reading, and Estimating | 15 |
| Metals | 12 |
| Concrete and Concrete Reinforcement | 8 |
| Roofing | 7 |
| Sitework, Footings, and Foundation | 6 |
| Masonry | 6 |
| Carpentry | 6 |
| Associated Construction Trades | 5 |
| OSHA Safety | 5 |
General Code, Plan Reading, and Estimating carries the most weight at 15 questions. Expect occupancy classifications, construction types, fire-resistance ratings, and practical estimating math. If you can read a set of plans quickly and do takeoff calculations under pressure, this section rewards you.
Metals is the second-heaviest topic at 12 questions. Steel joist types (K-Series, LH-Series, DLH-Series, joist girders, CJ-Series composite joists), steel deck profiles, erection bridging, and OSHA Subpart R steel erection safety are all fair game.
Concrete and Concrete Reinforcement (8 questions) covers mixture proportioning, field control testing, formwork, placement, and consolidation — practical, hands-on knowledge.
Roofing, Sitework, Masonry, and Carpentry each carry 6–7 questions. Associated Construction Trades and OSHA Safety round out the exam at 5 questions each.
Study in proportion to the weight. Fifteen questions on code and estimating means that topic alone is worth more than a third of what you need to pass.

Required Study Materials for the Tennessee BC-b Exam
This is an open-book test, which means your references are your lifeline — but only if they're organized. Here's what you'll need:
Required References:
- IBC 2021 — The International Building Code is your anchor for the 15-question General Code section. This is the one book to know cold.
- The Contractor's Guide to Quality Concrete Construction — Covers formwork, testing, placement, and finishing. Essential for the concrete topic.
- OSHA 29 CFR 1926 — Required for both the OSHA Safety questions and the Metals section's Subpart R steel erection requirements.
- Roofing Construction and Estimating — Covers slope, materials, underlayment, and estimating for the roofing topic.
- Modern Masonry — Brick, block, and stone; mortar types; and wall systems.
- Pipe and Excavation Contracting — Supports the sitework, soil classification, and excavation content.
- Gypsum Construction Handbook — Drywall, plaster, and ceiling systems for Associated Construction Trades.
- Technical Digest No. 9 — Handling and erection of steel joists and joist girders.
- SDI Manual of Construction with Steel Deck — Steel deck profiles, installation, and specs.
- Carpentry and Building Construction — Framing components, rafter layout, and engineered wood products.
Recommended Organization Tools:
- Redi-Tag Permanent Colored Tabs — 100 laser tabs in five colors. Color-code each book by topic so you can find answers in seconds, not minutes.
- Sharpie Highlighters — 12-pack in assorted fluorescent colors. Mark key tables, formulas, and definitions before test day. The exam allows highlighted books; use that to your advantage.
Study Tips for the Tennessee BC-b Exam
Organize before you study. Tab and highlight every book before you start drilling practice questions. Use a consistent color system: one color for definitions, another for code tables, another for formulas. On test day, you need to locate information in under 30 seconds.
Simulate real test conditions. PDF study guides are useful for learning material, but they don't prepare you for the clock. Our full practice exam matches the real Tennessee BC-b exam — 70 questions, 200-minute time limit, same topic breakdown. That pressure is part of the preparation.
Read every answer choice before committing. Work through choices in order. If option A looks correct, hold it as your current best. Keep going — each subsequent choice must actively beat the previous one to replace it. After you've read all four, verify your final answer actually addresses what the question asked.
Don't bleed time on hard questions. If a problem has you stuck, eliminate the obviously wrong choices first — even cutting two options significantly improves your odds — then make your best guess and move on. Flag it and come back if time allows.
Focus proportionally. Fifteen questions on General Code and Estimating. Twelve on Metals. Eight on Concrete. Study in that order of priority.
