What Is A AL-GC?

TL;DR
  • AL-GC is the NASCLA trade exam for Alabama's Building Construction (Commercial) contractor classification.
  • The exam has 115 questions, runs 5 hours 30 minutes, and requires a raw score of 81 to pass.
  • It's open book, computer administered, and allows a silent nonprinting nonprogrammable calculator.
  • Procurement and Contracting Requirements is the largest of the 12 domains - prioritize it.

What the AL-GC Actually Is

The term AL-GC, in the context of this site, refers to the Alabama Building Construction (Commercial) General Contractor Trade Exam - the licensing exam commercial contractors must pass to legally bid and build projects of $100,000 or more in the state of Alabama. It is not a generic industry designation or a national safety credential; it is a state-specific trade competency exam tied directly to the classification a contractor selects when applying for licensure through the Alabama Licensing Board for General Contractors.

If you've searched "what is AL-GC," you're likely trying to figure out whether this is the exam you need before you can legally take on commercial work in Alabama. For a deeper breakdown of the terminology itself, see AL-GC Meaning and What Does AL-GC Stand For?. This article focuses specifically on what the exam covers, how it's administered, and what candidates are expected to know.

Quick Definition: AL-GC is the trade knowledge exam (built on the NASCLA Accredited Examination for Commercial General Building Contractors) required for the Building Construction (Commercial) license classification in Alabama. It tests construction knowledge across 12 domains, not general business skills.

Who Administers the AL-GC Exam

Two separate organizations are involved. The Alabama Licensing Board for General Contractors is the regulatory body that approves applicants, sets requirements, and issues the license itself. PSI is the testing vendor that actually delivers the exam - the NASCLA Accredited Examination for Commercial General Building Contractors - at computer-based testing centers.

This distinction matters because approval and exam scheduling are two different processes. You don't simply register with PSI and sit for the test; you must first be approved by the Board, and only then are you eligible to schedule your exam session. Candidates who skip ahead and try to book a test date before securing Board approval often waste time and money.

Exam Format and Logistics

The AL-GC trade exam is deliberately long and detailed because it is meant to verify hands-on construction knowledge across an entire commercial building project, not just one specialty. Here's what the format looks like in practice:

  • 115 scored and potential experimental questions - up to 10 unscored experimental questions may be mixed in, but they still count against your time.
  • 5 hours 30 minutes total time allotted.
  • Raw score of 81 required to pass (not a percentage-based scaled score).
  • Computer administered at a PSI testing center.
  • Open book - candidates may bring approved reference materials, which changes how you should prepare compared to a closed-book test.
  • Calculator allowed, but it must be silent, nonprinting, and nonprogrammable.
  • Exam fee of $106 paid separately from the application fee.

If you're trying to gauge overall difficulty before committing to the process, How Hard Is the AL-GC Exam? Complete Difficulty Guide 2026 walks through what makes this exam demanding despite being open book.

Key Takeaway

Open book does not mean easy. With 115 questions and roughly 2.5 minutes per question on average, you don't have time to look up every answer - you need working knowledge and a well-tabbed reference book.

The 12 Content Domains

The AL-GC exam is built around the full lifecycle of a commercial construction project, from contract paperwork through finish work and building systems. There are 12 domains total:

  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

Procurement and Contracting Requirements is the largest domain on the exam, which surprises many candidates who assume the test is weighted mostly toward hands-on trade work like concrete or masonry. In reality, contract administration, bidding procedures, and procurement rules make up a substantial share of your score.

Procurement and Contracting Requirements

Because this is the largest domain, candidates should treat it as a first-priority study area rather than an afterthought.

  • Bid documents, contract types, and award processes
  • Change orders and modifications to scope
  • Specifications and how they interact with drawings

Site Construction and Concrete

These early-project domains cover the physical groundwork of a commercial build.

  • Excavation, grading, and soil considerations
  • Formwork, reinforcement, and curing requirements
  • Sequencing site work with foundation work

Mechanical, Plumbing, and Electrical Systems

These systems-focused domains test coordination knowledge more than installation detail.

  • How a GC coordinates subcontractor trades
  • Code-driven clearance and access requirements
  • Sequencing rough-in work with structural and finish trades

Because so much rides on knowing exactly how each domain is weighted and what topics live inside each one, it's worth reviewing AL-GC Exam Domains 2026: Complete Guide to All 12 Content Areas before you build a study plan. Trying to prepare without a domain-by-domain map is one of the most common reasons candidates run out of time on exam day.

Getting Approved to Sit for the Exam

Passing the trade exam is only one piece of becoming a licensed commercial general contractor in Alabama. Before you can even schedule the AL-GC exam, the Board requires a full application package:

  • Board approval of your application
  • A $300 prime application fee
  • Designation of a qualifying party for the license
  • Registration with the Alabama Secretary of State
  • Proof of liability insurance
  • A current CPA or approved-accountant financial statement showing at least $10,000 in both net worth and working capital, with no deficits
  • Documentation of at least three relevant completed projects
  • Three qualified references

This is a much more involved process than a typical certification exam, and it's easy to underestimate the paperwork timeline. For a step-by-step breakdown of each requirement and how to prepare the documentation in advance, see AL-GC Requirements 2026: Eligibility, Prerequisites & How to Qualify. If you want a full cost picture including the application fee, exam fee, and renewal cost, check AL-GC Certification Cost 2026: Complete Pricing Breakdown.

Financial Statement Reminder: The $10,000 net worth and working capital thresholds must both be met with no deficits. Candidates who wait until after Board approval to gather financial documentation often delay their exam scheduling by weeks.

The Companion Business and Law Exam

In addition to the trade exam covered throughout this article, Alabama requires a separate Alabama Business and Law exam. This is a distinct test from the 12-domain trade exam and covers business practices, licensing law, and related regulatory topics rather than construction methods and materials. Candidates should plan for both exams as part of the same overall licensing timeline, since the Board typically expects both to be completed as part of the full application process.

Eligibility Window and Renewal

Once you're approved to test, your eligibility lasts one year, and you're permitted unlimited attempts within that window. This gives candidates room to retake the exam if needed without restarting the entire application process, though each attempt still requires paying the exam fee.

After licensure, prime contractor licenses in Alabama renew annually for $200. Understanding this renewal cost up front helps you budget for the credential as an ongoing business expense rather than a one-time cost.

Who Actually Needs This Credential

Because Alabama licensure applies to commercial projects of $100,000 or more, this exam is aimed squarely at contractors who intend to bid and manage larger commercial builds - not small residential remodels or handyman-scale work. Typical candidates include:

  • Experienced construction supervisors or superintendents stepping up to run their own commercial contracting business
  • Estimators or project managers who need to become the designated qualifying party for a firm
  • Established contractors expanding from residential work into commercial-scale projects
  • Out-of-state contractors establishing an Alabama entity to bid on local commercial work

How to Approach Preparation

Given that Procurement and Contracting Requirements carries the most weight, and that domains like Mechanical and Plumbing Systems or Electrical Systems require coordination-level rather than installation-level knowledge, a smart prep sequence front-loads the heaviest domain early and leaves review time at the end for the more procedural material.

Weeks 1-2

Procurement and Contracting Requirements

  • Study contract types, bid procedures, and change order rules
  • Build a tabbed reference section for your open-book exam
Weeks 3-4

Structural Domains

  • Concrete, Masonry, Metals, and Wood
  • Focus on sequencing and material specification differences
Weeks 5-6

Envelope and Systems Domains

  • Thermal and Moisture Protection, Doors/Windows/Glazing, Finishes
  • Mechanical/Plumbing and Electrical coordination points
Week 7

Full Review and Timed Practice

  • Simulate the 5 hour 30 minute format with open-book materials
  • Revisit weak domains identified through practice questions
