ICC F12 National Standard Building Contractor Practice Exam

Many professionals often confuse the F12 certification with other contractor classifications. The main differences between Building Contractor B-1 and B-2 classifications relate to the scope and complexity of projects they can undertake:

• B-1 (General Contractor Class A): Authorized to build structures of unlimited height and area. These contractors can work on complex, large-scale commercial and institutional projects.

• B-2 (General Contractor Class B): Limited to constructing buildings up to three stories in height. These contractors typically handle smaller commercial projects and residential developments.

The F12 National Standard certification provides a recognized credential that aligns with B-1 and B-2 requirements in many jurisdictions, serving as evidence of a contractor’s proficiency in building code knowledge.

The ICC General Contractor Exam for the F12 certification consists of 80 questions that must be answered within 240 minutes, or 4 hours. To pass, you need a score of 70% or higher, just like the real test administered at Pearson Vue testing centers. The exam covers a wide range of topics, with the following breakdown based on the Denver, Colorado, exam content outline provided by the ICC:

• Administration: 6%
• Building Planning: 5%
• Plan Reading: 13%
• Life Safety: 9%
• Exterior Walls: 3%
• Roof Assemblies and Rooftop Structures: 8%
• Soils and Foundations: 10%
• Concrete: 5%
• Masonry: 11%
• Steel: 6%
• Wood: 18%
• Glass and Glazing: 1%
• Gypsum Board and Plaster: 3%
• Special Construction: 1%
• Energy Efficiency: 1%

Our ICC F12 Practice Exam mirrors this structure to ensure you’re well-prepared for the actual test day.
