- AL-GC stands for the Alabama Building Construction (Commercial) General Contractor Trade Exam, administered via PSI.
- The trade exam has 115 questions, a 5 hour 30 minute limit, and requires a raw score of 81 to pass.
- Procurement and Contracting Requirements is the largest of the 12 tested domains.
- Alabama licensure under this exam applies to commercial projects of $100,000 or more.
What AL-GC Stands For
AL-GC stands for the Alabama Building Construction (Commercial) General Contractor Trade Exam. It is the trade-knowledge examination that the Alabama Licensing Board for General Contractors requires as part of the licensing process for contractors who want to bid, contract, and build commercial projects in Alabama valued at $100,000 or more. The exam itself is developed as the NASCLA Accredited Examination for Commercial General Building Contractors and is delivered through PSI testing centers.
It's worth being precise here because the letters "AL-GC" get used loosely in conversation to mean several different things: the exam, the license, the qualifying party status, or the broader licensing process. On this site, and throughout our AL-GC Study Guide 2026, AL-GC always refers specifically to this trade exam pathway for Alabama's commercial general contractor classification - not a national certification, not a different state's program, and not a soft-skills credential. If you landed here wondering "is this the same AL-GC I saw referenced elsewhere," the answer for our purposes is no - this is Alabama-specific, commercial-classification-specific, and PSI-administered.
Who Regulates the Credential
The Alabama Licensing Board for General Contractors is the state body that approves applicants, issues licenses, and sets the rules around who must sit for the AL-GC trade exam. The Board does not write or grade the exam itself - that work is contracted to PSI, which administers the computer-based test at approved testing centers.
Because the Board and the testing vendor are separate entities, candidates deal with two different processes: Board approval (application, qualifying party designation, financial statement, references, project documentation) and exam scheduling (through PSI once the Board has cleared you to test). Our AL-GC Requirements 2026 guide breaks down each Board-side requirement in detail if you're still assembling your application.
Exam Format and Delivery
The AL-GC trade exam is a computer-administered, open-book test. That single fact shapes how most candidates should prepare - it is not a memorization test in the traditional sense, but a test of whether you can locate, interpret, and apply information quickly under time pressure.
- Length: 115 questions
- Time limit: 5 hours 30 minutes
- Passing score: a raw score of 81
- Cost: $106 per attempt
- Format: open book, computer administered
- Calculator policy: a silent, nonprinting, nonprogrammable calculator is allowed
- Experimental items: the exam may include 1-10 unscored experimental questions, and these count against your time limit even though they don't count toward your score
That last point trips people up. Because you can't identify which questions are experimental, you have to treat every question as if it counts - there's no strategy for skipping the "practice" ones. For a full breakdown of exactly what score you need and how the raw-score system works, see AL-GC Passing Score 2026: Exactly What You Need to Pass.
Key Takeaway
Open-book does not mean easy. With 115 questions in 5 hours 30 minutes, you have roughly under three minutes per question if you need to flip through references - plan your open-book strategy before test day, not during it.
The 12 Domains Behind the Acronym
The content behind the AL-GC acronym is organized into twelve domains that mirror how a commercial building actually goes together, from site work through finishes to the systems that make a building function. Understanding this structure matters more than memorizing the acronym itself, because the exam questions are drawn directly from these areas.
Domain 12: Procurement and Contracting Requirements
This is the largest domain on the exam, and it covers the business and contractual side of commercial general contracting - bidding procedures, contract types, bonding, and procurement rules that govern how commercial work is awarded and executed in Alabama.
- Expect a disproportionate share of questions here relative to other domains
- Contract and procurement terminology should be second nature before test day
Domains 1-11: The Trade Disciplines
The remaining domains cover the physical construction disciplines a commercial GC oversees or coordinates: General Requirements, Site Construction, Concrete, Masonry, Metals, Wood, Thermal and Moisture Protection, Doors/Windows/Glazing, Finishes, Mechanical and Plumbing Systems, and Electrical Systems.
- Each domain tests coordination and oversight knowledge, not just installer-level detail
- Cross-trade sequencing questions (e.g., how thermal protection interacts with masonry) are common
Because Procurement and Contracting Requirements carries the most weight, it deserves the most dedicated review time - but you can't ignore the other eleven, since a weak showing in even one or two trade domains can pull your raw score below 81. For a domain-by-domain breakdown with what to actually study inside each one, our AL-GC Exam Domains 2026: Complete Guide to All 12 Content Areas goes deeper than we can here.
| Domain # | Domain Name |
|---|---|
| 1 | General Requirements |
| 2 | Site Construction |
| 3 | Concrete |
| 4 | Masonry |
| 5 | Metals |
| 6 | Wood |
| 7 | Thermal and Moisture Protection |
| 8 | Doors, Windows, and Glazing |
| 9 | Finishes |
| 10 | Mechanical and Plumbing Systems |
| 11 | Electrical Systems |
| 12 | Procurement and Contracting Requirements (largest domain) |
Registration and Fee Mechanics
Passing the AL-GC trade exam is one requirement inside a larger application package the Board reviews before licensure. Knowing the full mechanics helps you understand why "AL-GC" isn't a standalone credential you can earn in isolation - it's woven into a broader approval process.
- Board approval must be obtained before you're eligible to sit for the exam
- A $300 prime application fee is paid to the Board
- Applicants must designate a qualifying party who will hold responsibility for the license
- Registration with the Alabama Secretary of State is required
- Liability insurance must be carried
- A current CPA or approved-accountant financial statement is required, showing at least $10,000 in both net worth and working capital, with no deficits
- At least three relevant completed projects must be documented
- Three qualified references must be provided
- A separate Alabama Business and Law exam must also be passed
Once approved, eligibility to test lasts one year, and within that window you get unlimited attempts at the trade exam. Prime licenses, once issued, renew annually for $200. If you're trying to budget the entire process - application fee, exam fee, insurance, and renewal - our AL-GC Certification Cost 2026: Complete Pricing Breakdown lays out every line item.

Who Actually Needs AL-GC
Not every contractor working in Alabama needs to pass this exam. It applies specifically to individuals or qualifying parties seeking the Building Construction (Commercial) classification, which governs projects at or above the $100,000 threshold. If your work stays under that dollar amount, or falls into a different classification entirely, the AL-GC trade exam may not apply to you.
In practice, the people preparing for this exam tend to fall into a few groups:
- Owners or principals of construction companies who need to serve as the qualifying party on a prime license
- Project managers or superintendents being positioned by a firm to become its designated qualifying party
- Experienced tradespeople expanding into general contracting oversight roles on commercial jobs
- Out-of-state contractors expanding operations into Alabama who need Alabama-specific licensure despite existing credentials elsewhere
Because the license is tied to a real business function - the ability to legally bid and contract commercial work above $100,000 - passing the AL-GC exam has direct career and revenue implications.

Mapping a Study Plan to the Acronym
Once you understand that AL-GC represents twelve weighted domains rather than a single body of trivia, your prep plan should follow the same logic. A reasonable approach is to spend more calendar time on Procurement and Contracting Requirements given its size, while still rotating through every trade domain at least once before test day.
Procurement and Contracting Requirements
- Review bidding, bonding, and contract-type terminology since this is the largest domain
- Practice locating procurement rules quickly in your open-book references
Structural and Envelope Domains
- Work through Concrete, Masonry, Metals, and Wood
- Then move into Thermal and Moisture Protection and Doors, Windows, and Glazing
Systems Domains
- Cover Mechanical and Plumbing Systems and Electrical Systems
- Focus on coordination points between trades rather than installer-level detail
General Requirements, Site Construction, and Finishes
- Close out remaining domains
- Run full-length timed practice sessions to build stamina for the 5 hour 30 minute exam
Timed practice matters here specifically because of the open-book format - you need to rehearse flipping through reference material under a clock, not just recognize correct answers in isolation. For a deeper look at how difficult candidates generally find this exam and where they lose the most time, read How Hard Is the AL-GC Exam? Complete Difficulty Guide 2026. If you want a condensed reference to keep nearby during final review, our AL-GC Cheat Sheet 2026: One-Page Review of Must-Know Facts summarizes the highest-yield facts in one page.
You can also build familiarity with the question style by running structured practice sessions on our AL-GC practice test platform, which mirrors the domain breakdown described above so you can see where your weak spots actually are before spending money on a real attempt. Combining that kind of targeted practice with the study timeline above tends to produce a much steadier path to the 81 raw-score threshold than generic review alone.
