As a NASCLA Prep instructor, I've guided hundreds to exam success. When I first pursued my contractor's license, I mistakenly thought industry experience would be enough. I was wrong! After years of helping contractors through our courses, I've identified the common pitfalls that challenge even veterans. Let me share these mistakes so you can avoid them and pass your contractor licensing test on your first attempt.
Key Takeaways
Don't underestimate business sections—they're equally weighted with technical knowledge.
Consistent daily study beats last-minute cramming every time.
Practice tests reveal knowledge gaps before they cost you points.

Underestimating the Scope of the NASCLA Examination
The first and perhaps most dangerous mistake is underestimating just how comprehensive the NASCLA contractor examination really is. This isn't just a simple test of your construction knowledge—it's a rigorous assessment covering business management, financial management, tax laws, employment requirements, contract management, project management, safety protocols, and much more.
When I first looked at the NASCLA exam content outline, I focused primarily on the construction topics I was comfortable with and glossed over the business and legal sections. This was a critical error. The exam gives equal weight to all sections, and many questions focus on administrative aspects of running a contracting business that you might not encounter in your daily work.
Pro tip: Treat each section of the study material with equal importance, regardless of your comfort level. The business and legal portions are just as crucial as the technical construction knowledge.
Relying Solely on Work Experience
With over 15 years in construction before taking my exam, I assumed my hands-on experience would be my greatest asset. While practical knowledge is invaluable, the NASCLA test often asks about specific regulations, calculations, and procedures that you might not regularly use in the field.
For example, I knew how to estimate materials for a job, but the exam required a more standardized approach to quantity takeoffs than the methods I'd developed on my own. Similarly, I understood basic workplace safety, but the exam tested specific OSHA regulations and reporting requirements I hadn't memorized.
Pro tip: Use your experience as a foundation, but recognize that the licensing examination requires standardized knowledge that might differ from your on-the-job practices.
Using Outdated Study Materials
Construction codes, regulations, and business requirements change regularly. One costly mistake I see contractors make is using hand-me-down study guides or outdated materials from colleagues who took the test years ago.
When I first started studying, a friend gave me his materials from three years earlier. I later discovered that several key code references had been updated, and tax information was completely outdated. This could have led to me answering numerous questions incorrectly.
Pro tip: Invest in current, NASCLA-approved study materials like those we offer at NASCLA Prep. Our resources are continuously updated to reflect the latest exam requirements. The money spent on up-to-date resources will pale in comparison to the cost of retaking the exam or delaying your licensing.

Cramming Instead of Consistent Study
The contractor licensing examination covers an enormous amount of material. I've watched many capable contractors fail because they attempted to cram all their studying into the week before the test.
I made this mistake myself initially, scheduling my exam and then procrastinating until two weeks before the test date. The sheer volume of information was overwhelming, and I ended up rescheduling because I knew I wasn't prepared.
Pro tip: Create a study schedule at least 2-3 months before your exam date. Consistent, focused studying for shorter periods (1-2 hours daily) is far more effective than marathon cram sessions.
Neglecting to Take Practice Tests
Perhaps the most valuable preparation tool is practice examination questions, yet many candidates spend all their time reviewing content without testing their knowledge. Practice tests serve multiple purposes:
They familiarize you with the question format and testing environment
They highlight weak areas that require additional study
They build your mental stamina for the actual 3+ hour examination
They help reduce test anxiety through familiarity
When I finally buckled down with proper preparation, I incorporated weekly practice tests into my study routine. These mock exams revealed gaps in my knowledge about lien laws and financial statements that I would have otherwise missed.
Pro tip: Take regular practice tests throughout your study period, not just at the end. Our NASCLA Prep practice exams are designed to mimic the actual test format and difficulty level. Review every incorrect answer to understand why you missed it and strengthen those knowledge areas.
Skipping the Business and Financial Sections
Many construction professionals are more comfortable with the technical aspects of the industry than with business management topics. As a result, I've noticed a tendency to focus heavily on the construction knowledge sections while neglecting the business and financial components.
The NASCLA examination places significant emphasis on:
Financial statement analysis
Tax requirements and reporting
Business structures and their legal implications
Contract law and proper documentation
Employee classification and requirements
Lien laws and dispute resolution
These sections often determine whether candidates pass or fail. I know contractors with decades of technical expertise who failed the exam multiple times because they didn't adequately prepare for these business-oriented questions.
Pro tip: If business and financial topics aren't your strength, allocate extra study time to these sections and consider seeking out specialized resources that explain these concepts in contractor-friendly terms.
Not Understanding the Reference Materials
The NASCLA examination is typically an open-book test, allowing you to use approved reference materials. However, many candidates mistakenly believe this means they don't need to study as intensively.
In reality, if you're not thoroughly familiar with your reference materials before the exam, you'll waste precious time flipping through pages trying to find information. The test is timed, and searching for every answer is simply not feasible.
I made this mistake during my first preparation attempt, thinking I could just look up anything I didn't know. During practice tests, I quickly realized that without knowing exactly where to find information in my references, I would never finish on time.
Pro tip: Tab your reference materials by topic, create a personal index of key information, and practice using your references during timed practice tests.
Ignoring Test-Taking Strategies
Beyond knowledge of the material, test-taking strategies play a crucial role in passing the NASCLA examination. Some contractors overlook this aspect, assuming that knowing the content is sufficient.
Effective strategies include:
Reading each question twice to ensure understanding
Answering easier questions first to build confidence and momentum
Flagging difficult questions to return to later
Using the process of elimination for challenging multiple-choice questions
Managing your time by periodically checking how many questions remain
When I took my exam, I noticed several questions that seemed straightforward at first glance but contained subtle details that changed the correct answer. Taking the time to read carefully saved me from several potential mistakes.
Pro tip: Practice these strategies during your mock exams so they become second nature on test day.
Letting Stress Overwhelm You
Test anxiety is real, and it can significantly impact your performance. I've known highly knowledgeable contractors who froze up during the exam due to stress.
Before my exam, I was so anxious about the financial sections that I could barely sleep the night before. This affected my concentration during the first hour of the test until I managed to calm myself down.
Pro tip: Develop stress management techniques as part of your preparation. This might include deep breathing exercises, positive visualization, or simply ensuring you're well-rested before the exam.
Failing to Learn from Practice Mistakes
One of the most valuable aspects of practice tests is identifying your weak areas. Yet I've observed many candidates take practice exams, note their incorrect answers, but never go back to strengthen their understanding of those topics.
After each practice test, I started keeping a "mistake journal" where I recorded questions I missed and researched the correct answers in depth. This targeted approach allowed me to systematically eliminate my knowledge gaps.
Pro tip: Create a system for reviewing and learning from practice test mistakes. Each incorrect answer is an opportunity to improve before it costs you on the actual exam.
