NASCLA Commercial exam prep FAQ
How long is the free check?
The free check has 10 practice questions, is untimed and takes about 29 minutes. You see the answer and explanation after each one. When you want exam pace, the course has full-length timed exams: 115 questions on the real 330-minute clock.
What does the free check cover?
All 12 subject areas on the NASCLA content outline, weighted the way the exam is. Procurement and contracting requirements and general requirements make up 56 of the 115 scored questions, so they make up most of the check too.
What is in the full NASCLA Commercial course?
Original practice questions, each explained, full-length timed exams of 115 questions on the 330-minute clock, 12 modules of lessons that teach where to look in your books, flashcards with spaced review and a week-by-week study plan set to your exam date. Seal, your AI study buddy, walks you through any question you miss.
Do I need all 24 reference books?
None of the 24 listed references are provided at the test center, so any book you want open on exam day is one you bring. The course teaches which book answers which kind of question, and the free tabbing guide lists the tabs for every book, so your lookups take seconds, not minutes.
What do I need to bring to the real exam?
The exam is open book, and you bring your own copies of the listed references. None are provided at the test center, though a diagram and blueprint packet is handed out on site. Books may be highlighted and tabbed with permanent tabs, but not written in. A silent, non-programmable calculator is allowed.
Which states accept the NASCLA exam?
NASCLA lists 20 agencies in 18 states and territories: Alabama, Arizona, Arkansas, California, Florida, Georgia, Louisiana, Mississippi, Nevada, New Mexico, North Carolina, Oregon, South Carolina, Tennessee, Utah, the U.S. Virgin Islands, Virginia and West Virginia. In most of them a pass replaces the state trade exam.
What does passing do for my license?
In the states and territories that accept it, passing stands in for the state trade exam, so you skip that state's own trade test. Each state's application, its business and law exam and its other requirements still apply.
Is the check free?
Yes. You can start the check and see your score and weakest subject area for free, with no signup or payment. Your score in each subject area unlocks when you add your email.
Where does the practice content come from?
These are original practice questions written to the published NASCLA content outline. We never use real or recalled exam items and we never reproduce text from the reference books. Each explanation names the listed reference and topic to look up.
