Frequently Asked Questions


What is the NASCLA Accredited Examination Program?

The NASCLA Accredited Examination Program is designed to help participating states by providing one trades licensing examination that is accepted by all participating jurisdictions.

The NASCLA Accredited Examination Program is NOT a nationally recognized license. Contractors will still have to meet additional state licensure requirements within each participating state to obtain their licenses.

Why take the NASCLA Accredited Exam?

The NASCLA Accredited exam benefits contractors who need licenses in multiple states. If your business will expand into any of the participating states, you will save time and money by passing the NASCLA exam.

By passing the NASCLA exam, you will avoid having to take multiple trades exams in other states. You will still need to pass a Business & Law exam in each of the States (except Arkansas).  Arkansas will accept the NASCLA Accredited exam as both the Trades and Business/Law.

What states is the NASCLA exam accepted in?

Do I have to be approved to take the NASCLA exam?

Yes. Effective November 1, 2016, applicants must get pre-approval from the National Association of State Contractors Licensing Agencies (NASCLA) to take the NASCLA exam.

Applicants can apply for approval online at ned.nascla.org. Once approved, the individual’s name will be forwarded from NASCLA to PSI. PSI will then send the applicant an email with information about how to schedule their exam.

Can I write in my reference books and still bring them to the exam?

References may be highlighted, underlined, and/or indexed (tabbed with permanent stick tabs), however they may NOT otherwise be written in or marked in any way. Temporary tabs, such as Post-It notes, are not allowed and must be removed from the reference before the exam will begin.

What subject areas will be covered on the NASCLA Accredited Exam?

There are 115 questions and you must get 81 answers correct. You will have 330 minutes to complete the exam. The subjects covered in the exam are listed below, however, the questions are taken at random from a large pool of questions making sure that all contractors are taking a different exam.

The exam is based on information found in the reference materials we have listed above as well as trade knowledge or general industry practices. Except for Code books, you may base your answers on later editions of references as they become available. For Code questions, the examinations will be based only on the edition of the Code book listed on the candidate bulletin.

Is the NASCLA exam an open book exam?

The NASCLA exam is an open book exam. All of the books listed on the candidate bulletin may be brought into and used during the exam. Books will not be provided to you at the exam center. If you are in need of books, we offer all of the references listed on the Candidate Bulletin for sale in our Bookstore, or in our complete NASCLA Prep Package.

What can I expect from the NASCLA Exam Prep course?

Our NASCLA Exam Prep course is designed to help you maximize your study time.

The remainder of the lessons are devoted to each book on the Candidate Bulletin. Each of these lessons help you get to know the layout of the books and key information that can be found within. Each book has a quiz dedicated solely to the material in that book.

Finally, you will find the practice test at the end of the course. This practice test consists of a pool of over 1,000 questions, to help you practice taking an exam as well as determine which areas you need to brush up on further.

How long does it take to complete your NASCLA Exam Prep course?

That question is almost entirely up to you!

There are 16 hours of videos, which walk you through each reference allowed in the exam. There are also over 1,000 practice questions, to help you gauge your knowledge and practice using your references in an exam-like setting.

We recommend going through the entire course at least once. After that it is up to you. Some may want to go through the whole course multiple times. You might also find yourself taking note of particular topics you would like to devote more time to, and just going back later to study those areas.

We recommend for you to spend as much time with the course as is necessary to really get to know your reference materials, and be comfortable finding answers with the texts--this will ensure your success on the exam!

Does the NASCLA exam work for residential construction?

The following states allow NASCLA accreditation for residential contractors: AR, FL, GA, LA, MS, NC, NV, OR, SC, TN, UT, Virgin Islands, WV.

About the Courses

Once I order the course, how long before I can start?

You may begin immediately! Simply click the Login button in the upper right-hand corner on your desktop or in the upper-right menu on mobile. Once you’ve entered your login and password, you will be taken to your courses. Follow the instructions and enjoy!

Once I start an online course, will I be able to start and stop at anytime?

Our courses are available online 24/7 and you are able to log in and log out at any time during the course. If you are going to be away from your computer for more than 10-15 minutes, simply log out. When you log back in, you will be able to re-enter the lesson you were last in.

How long do your continuing education courses take to complete?

Continuing education requirements vary by state. Each course lists a minimum number of credit hours required to complete the course.

How long do your exam prep courses take to complete?

Each course lists the total amount of hours for the course. However, we cover materials quickly and many contractors like to re-watch materials. In other words, this question really depends on your learning style. We recommend that you go through the course as many times as you need to be comfortable with the material and any applicable reference books. The more familiar you are with the materials, the better you will do on your exam!

How long do I have the courses?

We allow up to 6 months for you to complete the courses. During the six months you have unlimited, 24/7 access. If you need additional time, please contact our offices to arrange an extension (please note: a fee may apply).

Are there tests in the courses?

This varies depending on whether the course is continuing education or exam prep.

There are no quizzes for continuing education courses in Michigan. All other states with continuing education require quizzes to check completion progress.

In exam prep courses there will be a short quiz at the end of each lesson and there is also a longer practice test at the end of each course. These quizzes and tests will help you practice taking an exam and identify areas you may wish to study more.

If I fail a practice test, do I have to take it again?

Practice tests are just that: for practice. You will have the opportunity to retake the practice tests until you do pass. The practice tests are there to help you get used to the process of using your reference materials and finding the correct answers during an exam. If you don’t pass on the first try, take the time to note what sections of the material you need to review.

Once I complete a course, can I still go back and review the lessons and quizzes?

You are able to review the lessons and quizzes at any time during the six months you’ll have access to the courses.
