The National Police Officer Selection Test (NPOST) is a standardized written examination used by law enforcement agencies across the United States to screen police officer candidates. Our free NPOST practice test PDF includes sample questions covering all four battery sections so you can study anywhere — on the bus, at the gym, or away from a screen.
Download the PDF, print it out, and work through reading comprehension, arithmetic, writing, and incident report questions at your own pace. Use it alongside online practice tests to build the speed and accuracy you need to meet — and exceed — the minimum passing standards set by your hiring agency.
The NPOST Reading Comprehension section presents short passages drawn from law enforcement contexts — department policies, legal statutes, incident reports, and procedural directives — followed by multiple-choice questions. You must identify the main idea, draw logical inferences, determine the meaning of words in context, and distinguish between facts and opinions presented in the text. Strong reading comprehension is critical for officers who must interpret laws, court orders, and written directives accurately in the field. Practicing with dense, policy-style texts in the PDF will sharpen both your reading speed and retention.
The Arithmetic section tests fundamental math skills that officers use daily: addition, subtraction, multiplication, and division of whole numbers and decimals; working with fractions; calculating percentages; basic ratio and proportion problems; and interpreting simple data tables. Questions are presented as word problems or straightforward calculations. No advanced algebra or calculus is required — the focus is on accuracy and speed with essential operations. Officers frequently use math in the field for calculating BAC levels, completing evidence logs, estimating distances, and writing accurate numerical data in reports. Practicing without a calculator — as most NPOST administrations prohibit one — builds the mental math fluency you need.
The Writing section assesses grammar, punctuation, spelling, and sentence structure through multiple-choice questions. You may be asked to identify the correctly punctuated version of a sentence, choose the proper verb tense, select the best word to complete a sentence, spot a spelling error, or reorder sentence components for clarity. Police officers produce written reports that serve as legal documents, so clear and accurate writing is a core job competency. Common topics include subject-verb agreement, comma usage, apostrophes, commonly confused words (affect/effect, their/there/they're), and active versus passive voice.
The Incident Report Writing section evaluates your ability to observe a scene, retain relevant details, and apply that information to complete an accurate report. You are typically given a brief narrative or set of facts about an incident and then asked questions about what information should or should not be included in a report, how to sequence events logically, or how to select the most precise language to describe an observation. Officers' reports must be factual, complete, chronological, and free of subjective interpretation — the exam tests whether candidates understand these principles before they enter the field.
The NPOST is administered by individual law enforcement agencies, civil service commissions, and police departments at their designated testing locations. There is no single national testing body — each agency procures and proctors the exam independently, which means test dates, registration procedures, and fees vary by jurisdiction. Some agencies conduct testing in large group settings at community centers or government offices; others use contracted testing companies. Always contact the specific department you are applying to for exam schedules, registration links, and any required identification or documentation.
Most agencies require candidates to score a minimum of 70% on each of the four NPOST sections to advance in the hiring process. However, this threshold is agency-specific — some departments set a higher cutoff (75% or 80%) to narrow the candidate pool further. A low score on one section typically cannot be offset by a high score on another; each section must meet the minimum independently. After the written exam, passing candidates typically move on to additional screening stages, which may include background investigation, polygraph examination, psychological evaluation, and oral board interviews.
Several standardized law enforcement written tests are in use across the U.S. The NPOST is a national instrument produced by the International Public Management Association for Human Resources (IPMA-HR) and used broadly by agencies that want a validated, research-backed selection tool. The PELLETB (Peace Officer Standards and Training Entry-Level Law Enforcement Test Battery) is specific to California POST and tests reading, writing, and reasoning with a different structure than the NPOST. State-specific POST Entry-Level exams (used in Florida, Texas, and others) align with each state's training and curriculum standards. If you are applying in California, focus on PELLETB prep; for most other states, the NPOST or a similar national instrument is more likely. Always confirm with the hiring agency which exam they administer.
The NPOST measures cognitive and written communication skills only. Physical fitness is evaluated through a separate Physical Abilities Test (PAT) or Physical Fitness Test (PFT), which agencies design based on the bona fide physical demands of police work. Common PAT components include a timed 1.5-mile run, push-ups, sit-ups, and a sit-and-reach flexibility test. Some agencies use job-simulation obstacle courses. Physical and written testing are typically administered at different stages of the hiring process — candidates who pass the written exam are usually invited to a subsequent physical test date.

Try these questions from our free NPOST Police Test practice tests. The correct answer and an explanation follow each question.
Officer Miller pulls over a driver for speeding. As he approaches, he recognizes the driver as an off-duty officer from a neighboring police department. The off-duty officer apologizes and asks if Officer Miller can give him 'a break.' What is the most ethical and professional action for Officer Miller to take?
Answer: B. Issue a citation for the speeding violation, just as he would for any other citizen.
The most ethical action is to enforce the law impartially, regardless of the violator's profession. Treating a fellow officer differently from other citizens undermines public trust and creates an appearance of impropriety. Calling a supervisor is an unnecessary escalation, and deceptive actions are unprofessional.
During a foot patrol an officer notices a broken window at a store. What should the officer do FIRST?
Answer: A. Note the exact location, time, and condition before taking further action
Initial documentation of observations preserves scene details that are essential for the investigation.
A crime scene is described as being located southwest of the police station. To travel directly from the station to the scene, an officer must travel in which two directions?
Answer: D. South and west
Southwest means the location is both south and west of the reference point.
A patrol map shows a crime scene located northeast of the police station. To walk directly from the station to the scene, an officer must travel:
Answer: C. Both north and east
Northeast indicates the destination is both north and east of the starting point, requiring movement in both directions.
