ICC National Mechanical Exam Prep

National standard exams were developed by ICC as a way of analyzing a standardized level of education for licensed professionals nationwide. Although few state boards will issue a license based solely on the National Standard exams, many local and municipal agencies will. In any scenario, passing these exams is a testament to the knowledge and skill of anyone who passes.

Keep a cool head on the day of the exam by using our exam simulator, which builds a custom practice exam each time with questions very similar to the ones you will see on the real thing. To accommodate those inevitable questions that require another educated human to help, you can send our licensing support team a question 24/7 online and you can give us a call during weekday business hours. We can explain a concept, help with tricky tables, or clarify something that isn't quite "clicking". Pass any trade exam with RocketCert and Accelerate and Advance Your Career.

How do I obtain a license with ICC Mechanical Exams?

Passing these exams alone is not enough to obtain a license. Applicants must submit a license application with the proper state or local boards and satisfy their individual licensing requirements. Review the requirements prior to sitting for the exam. The best place to find more details about the requirements is by contacting the issuing board directly.

Most places require license holders to complete continuing education every year or two years in order to renew the license. We offer state-approved continuing education for trades across the country.

Review License Requirements

The first step is to review and understand all of the licensing requirements for the specific license you are seeking. Many places have financial and legal requirements for licensure.

Obtain Pre-approval

Some licensing agencies may require you to apply through them prior to testing with ICC, while others may not. Please contact your local licensing agency or review the appropriate National Contractor/Trades Examination Information Bulletin on the Code Council’s website.


It's never too soon to start studying for the exam. It covers a broad range of topics and you must wait 10 days before retaking a failed exam.

Pass The Exam

Once you feel comfortable with the content and have passed multiple practice exams, it's time to schedule the exam. You can schedule the exam on the PearsonVUE website.


Once you pass the exam, you will receive a physical copy of your passing score at the facility. You may also request a Replacement Result Letter directly from ICC.
