Frequently Asked Questions
What is the NFSI (National Firefighter Selection Inventory)?
The NFSI is a firefighter entry exam developed by IO Solutions (IOS) used by departments across the U.S. It measure both cognitive skills - like reasoning, comprehension, and problem solving - and behavioral traits such as teamwork, stress tolerance, and motivation.
What's on the NFSI exam?
The NFSI includes two parts:
Cognitive Abilities (105 questions) - covers verbal comprehension, deductive and inductive reasoning, information ordering, and math-related problem solving
Behavioral Section (50 questions) - assesses personality traits important to firefighters, such as teamwork, integrity, and emotional stability
Is the NFSI hard?
It can be challening, especially the reasoning and behavioral portions that test judgment under pressure. However, candidates who practice with realistic simulations and detailed feedback, like our premium prep provides, typically perform much higher on the actual exam.
How is your NFSI practice test different from free versions online?
Most free practice tests only cover basic cognitive skills or short sample questions. Many are actually generic firefighter test prep not tailored to the NFSI exam. Our prep mirrors the real exam structure, provides unlimited full-length tests with realistic scoring, and includes personality mapping to show how your responses align with firefighter traits -- a feature no other prep site offers.
How long will I have access after purchase?
You'll get 1 month of unlimited access to NFSI practice tests. That's enough time to retake the practice exams, track improvement, and build confidence before test day. Your plan will expire automatically at the end of the time period, so you don't need to worry about remembering to cancel or auto-renew charges.
Can I practice specific sections, or do I have to take the full exam each time?
You can choose! Practice the full NFSI simulation or focus on specific areas like cognitive reasoning or behavioral sections. Most candidates start with the full exam then hone in on the sections they want to improve.
Do your NFSI questions match the real exam?
Our team modeled each question type and format after the official IOS NFSI specifications, including cognitive skills and firefighter-relevant scenarios. You'll get the most realistic prep available.
What is "personality mapping" and how does it help me?
Our system analyzes your responses in the behavioral section to show how you align with key firefighter traits like teamwork, stress tolerance, and motivation. This helps you understand what the test is measuring and how to respond effectively.
Can I use the prep on my phone or table?
Absolutely. Our NFSI prep platform is fully mobile friendly, so you can study anytime.
What happens after I finish a practice exam?
You'll receive a detailed score breakdown by section, plus downloadable explanations for every incorrect response. For behavioral items, you'll see which dimensions you scored strongest in and where to improve.
