National Firefighter Selection Test Prep
Last updated: September 2026
NFST is used by fire departments across the U.S. and Canada to screen entry-level firefighter candidates. It's administered by two different companies (Stanard & Associates and Fire & Police Selection, Inc.) under similar names, both testing overlapping core skills: reading, math, and situational judgment. Use these free practice questions to prepare for the core content common to both versions.
Important Note on Two Different NFST Exams
Two separate companies administer exams under the NFST name. Stanard & Associates' National Firefighter Selection Test includes sections like Mathematical Reasoning and Listening Comprehension (based on a passage read aloud by the exam administrator). Fire & Police Selection, Inc.'s National Fire Select Test includes Reading Ability, Mathematical Reasoning, Map Reading, Writing Ability, and Human Relations/situational judgment sections. If you know which company your target fire department uses, confirm the exact format directly — this page covers the core skills common to both versions.
NFST Exam Format & Structure
Used as an initial civil service screening benchmark, NFST-style exams evaluate essential cognitive skills and interpersonal judgment critical for firefighting recruits.
- Mathematical Reasoning: Practical arithmetic word problems involving tank volumes, discharge rates (GPM), hose lengths, friction loss, and operational budgeting without a calculator.
- Reading Comprehension: Assessing candidate ability to understand departmental standard operating guidelines (SOGs), training manuals, and hazardous materials protocols.
- Human Relations / Situational Judgment: Scenario-based questions testing team dynamics, chain of command, ethical integrity, and public interaction.
- Map Reading & Navigation: Evaluating spatial awareness, grid navigation, street directionality, and detour routing during emergency responses.
- Writing & Grammar: Testing vocabulary, correct sentence construction, punctuation, and clear incident report drafting.
- Listening Comprehension (Stanard & Associates): Retaining critical verbal operational details from a simulated dispatch or briefing under time pressure.
Most municipal fire departments require candidates to achieve at least 70% to 80% on each individual cognitive section to advance to physical agility testing (CPAT) and oral board interviews.
What NFST Exams Generally Cover
Mathematical Reasoning
Basic arithmetic word problems relevant to firefighting scenarios including flow rates, hose layout, pressure, and capacity calculations (no advanced algebra or calculus required).
Reading Comprehension
Understanding written department guidelines, safety protocols, and technical passages, answering questions based strictly on the given text without outside assumptions.
Human Relations / Situational Judgment
Realistic workplace scenarios followed by multiple response options, where you identify both the MOST and LEAST appropriate responses to the same scenario.
Map Reading & Navigation
Interpreting street grids, one-way avenues, construction closures, and compass directions to determine the most direct and legal route to an emergency scene.
Writing Ability & Technical Grammar
Clear written communication skills, spotting misspelled words, subject-verb agreement, and structured factual reporting.
Listening Comprehension (Select Versions)
Retaining and answering questions based on a passage read aloud, testing structured note-taking and factual recall under timed pressure.
Why the 'Most vs. Least Appropriate' Format Trips People Up
Situational judgment questions on NFST-style exams often ask two separate questions about the same scenario — one for the most appropriate response and one for the least appropriate. Candidates who don't realize both are being asked about the same scenario, or who apply personal opinion rather than the job-relevant standard being tested, often lose points unnecessarily.
Free NFST Practice Questions
A fire engine responds to a structure fire with a full 750-gallon onboard water booster tank. The attack crew deploys two 1.75-inch attack handlines, with each handline flowing water at a continuous rate of 125 gallons per minute (GPM). If no external hydrant water supply has been established yet, how many minutes of continuous firefighting water can the booster tank supply before running completely empty?
An engine company needs to lay a 5-inch large diameter supply hose (LDH) from a municipal fire hydrant to an apparatus stationed 675 feet away. The supply hose is stored in standard 50-foot sections. How many full 50-foot sections of hose must the crew connect to cover the entire distance, and how many feet of excess hose slack will remain?
Passage: "Department Standard Operating Guideline (SOG) 204 requires all suppression personnel to conduct a daily operational inspection of their assigned Self-Contained Breathing Apparatus (SCBA) at the beginning of each duty shift. The inspection must confirm that the air cylinder is filled to a minimum of 90% of its rated working pressure (at least 4,050 psi for a 4,500 psi rated cylinder). If the cylinder pressure is below 90%, the firefighter must immediately swap the cylinder for a fully charged unit from the station reserve rack before apparatus roll-call. Any structural defect, seal deterioration, or regulator malfunction must be tagged out of service and reported directly to the company officer." According to SOG 204, what action is a firefighter required to take if an inspection reveals their 4,500 psi SCBA cylinder has an internal pressure reading of 3,800 psi?
Based ONLY on the provided passage in SOG 204 above, what is the mandatory protocol when a firefighter identifies a mechanical defect or deterioration in the SCBA facepiece seal or pressure regulator?
Scenario: Firefighter Jenkins is assigned to Station 4 on probationary status. During daily morning apparatus checks, Jenkins notices that Senior Firefighter Miller consistently skips operational testing on the hydraulic rescue tool (jaws of life) and simply signs off on the station logbook as "Inspected & Operational." When Jenkins asks Miller about it, Miller laughs and says: "That tool was tested two days ago and ran fine; don't worry about it so much, kid." Which of the following is the MOST appropriate response for Firefighter Jenkins in this situation?
Scenario: (Refer to the same scenario above regarding Senior Firefighter Miller skipping hydraulic rescue tool checks). Which of the following is the LEAST appropriate action for Firefighter Jenkins to take in this situation?
Scenario: Engine 7 is dispatched from Fire Station 7, located at the intersection of 1st Avenue and Maple Street, to a report of a commercial fire at 5th Avenue and Oak Street. Grid Specifications: • Avenues (1st Ave through 5th Ave) run North–South, spaced 1 block apart from West to East (1st Ave is furthest West, 5th Ave is furthest East). • Streets (Maple St, Pine St, Oak St) run West–East, spaced 1 block apart from North to South (Maple is furthest North, Pine is 1 block South of Maple, Oak is 1 block South of Pine). • 3rd Avenue is completely CLOSED to all traffic between Maple Street and Oak Street due to a water main break. Which of the following describes the shortest, unobstructed legal route for Engine 7 to reach the incident?
Scenario: A rescue ambulance is transporting a critical patient from 5th Avenue and Oak Street to the Regional Trauma Center located at 2nd Avenue and Maple Street. Grid Conditions: • 1st through 5th Avenues run North–South (1st is West, 5th is East). • Maple, Pine, and Oak Streets run West–East (Maple is North, Pine is center, Oak is South). • Pine Street is designated as a ONE-WAY street heading WESTBOUND ONLY (traffic flows only from East to West). • Maple Street and Oak Street are standard two-way streets. • 3rd Avenue is closed North–South between Maple and Oak. Which of the following routes provides a direct, legal route to the hospital using the one-way street effectively?
How to Prepare for the NFST
