There is no single national police written exam in the United States. The test you take depends on the department, state, civil-service system, or testing provider used in that hiring process.
Some agencies use a reading-and-writing exam such as California POST’s PELLETB. Others use a vendor test such as National Testing Network’s FrontLine National. Some departments use their own civil-service or entry-level examination.
That is why the best first step is not buying a random “police exam” study book. Find out the exact test name used by the department you are applying to, then prepare for that test.
The content varies, but entry-level police exams commonly test some combination of:
A police written exam is usually not testing whether you already know criminal law, police policy, or tactical procedures. Entry-level candidates have not been through the academy yet.
National Testing Network says its FrontLine National Human Relations Test is designed for entry-level law enforcement and does not require prior law-enforcement knowledge. California POST likewise describes the PELLETB as a reading-and-writing assessment rather than a test of police law.
People often talk about “the police exam” as if every department uses the same one. They do not.
The POST Entry-Level Law Enforcement Test Battery—usually called the PELLETB—is one example of a state-developed police entry test.
California POST currently describes the PELLETB as a multiple-choice examination measuring reading and writing ability. Since January 1, 2025, the CLOZE section has been removed. The current test has four sections:
POST’s current agency FAQ says candidates receive 2¼ hours for instructions and exam time. California agencies can also use another professionally developed and validated reading-and-writing test instead of the PELLETB.
Another common example is the FrontLine National law-enforcement exam administered by National Testing Network (NTN).
NTN describes three main components:
Current agencies using FrontLine can set their own passing scores. San Francisco Police Department, Garden Grove Police Department and University of Toledo Police Department all use FrontLine in current recruiting, but their hiring requirements are not identical.
That is a good example of an important rule: the testing provider can be the same while the department’s passing standard is different.
Some police departments recruit through a city or state civil-service system. Those systems may use their own entry examination, eligibility list, scoring rules and retest periods.
Other agencies use professionally validated tests developed specifically for their jurisdiction.
Do not assume an NTN study guide will prepare you for a POST test, or that a PELLETB score can automatically be transferred to a department using a different examination.
It is often one of the earliest screening stages.
A typical sequence may look like:
The order varies. California POST publishes a prototypical selection process with the written reading-and-writing exam near the beginning, while individual agencies can organize additional steps differently.
Our Police Hiring Process hub shows how all of these stages fit together.
That depends partly on your existing reading and writing skills and partly on the exam you are taking.
The material is usually not difficult because it contains advanced police knowledge. It can be difficult because you have to read carefully, work under time pressure, remember details, choose between similar answer options and write clearly.
For many applicants, the biggest problems are ordinary skills they have not practiced in years:
California POST says PELLETB performance is strongly related to academy performance and recommends improving reading and writing skills rather than trying to memorize test questions.
This is the most important step.
Look at the current job announcement or recruiting page and identify the exam by name. If it only says “written exam,” contact the recruiting unit and ask whether there is an official study guide.
Do not train for a test from another state just because someone on Reddit said it was similar.
If the test provider publishes sample questions, start there.
California POST provides an official PELLETB Applicant Preparation Guide. NTN provides information about the structure of FrontLine National and also offers practice testing.
An official guide tells you more than a generic prep book because it shows the format, instructions and skill areas actually used by that exam.
Police work involves reading reports, statutes, policies, witness statements and other material where small details can matter.
Practice reading short passages and answering questions without repeatedly looking back at the text. Then check what you missed.
Pay attention to:
You do not need to write like a novelist. You do need to write clearly.
Review grammar, punctuation, sentence structure, spelling and common word usage. If a test asks you to choose between two versions of a sentence, clarity is usually more important than sounding sophisticated.
This matters especially for tests such as FrontLine National.
A police-style report should separate what you actually observed from assumptions. If a video shows a man wearing a red jacket walking away from a vehicle, write what you saw. Do not turn him into “the suspect fleeing the stolen car” unless the scenario actually gives you that information.
Focus on:
Our guide on how to read a police report is useful here because the same distinction between observation, statement and conclusion matters when you write one.
Some testing formats use video or audio scenarios. You may not be able to replay them as often as you want.
Practice watching a short news clip or neutral scenario once while writing down:
Then write a short factual summary from your notes.
Knowing the material is not enough if you run out of time.
Do at least some practice under realistic time pressure. Learn when to move on from a question rather than spending several minutes trying to make one answer perfect.
Some police exams include scenarios where several answers sound reasonable.
NTN’s FrontLine Human Relations Test, for example, measures judgment in enforcement, public relations and teamwork. NTN specifically says candidates do not need police-policy knowledge to answer the questions.
For an entry-level test, think in terms of broad professional principles:
Do not invent advanced tactics that were never mentioned in the scenario.
There is no universal passing score.
Even departments using the same exam can set different thresholds. Current FrontLine users provide a good example: agencies publish their own minimum scores for the Human Relations, Reading and Writing sections.
California PELLETB uses a T-score system, and local agencies can set their own minimum passing score.
Always use the score published by the department you are applying to.
Usually there is some kind of retest rule, but it depends on the exam and agency.
California POST currently requires applicants who retake the PELLETB to wait at least 30 calendar days between administrations. Testing sooner can lead to the new score being invalidated.
Other tests and civil-service systems use different waiting periods.
Before scheduling a second attempt, verify the retest policy with the provider or hiring agency.
Sometimes, but not automatically.
California POST allows authorized agencies to verify PELLETB results taken with another POST user agency, but the receiving department still decides whether it will accept the score and what minimum it requires.
NTN is designed to let candidates send scores to participating agencies, but each agency controls its own hiring standards and score requirements.
A score that qualifies you for Department A does not guarantee that Department B will accept it.
Follow the instructions from the testing provider or department exactly.
You may need government-issued identification, confirmation of your appointment, or other documents. Some exams are computer-based; others are still paper-and-pencil.
California POST states that the PELLETB is currently administered in paper-and-pencil format. NTN offers testing through its own testing network and participating processes may have different instructions.
Do not assume calculators, notes, phones or personal study materials are allowed.
No. Departments and states use different exams and testing providers.
Usually not for an entry-level reading, writing or situational-judgment test. The academy is where you receive formal police training. Use the official test guide to see what your exam actually measures.
No. PELLETB is California POST’s entry-level reading-and-writing test. FrontLine National is a separate NTN law-enforcement testing system with Human Relations, Report Writing and Reading components.
California POST’s current agency FAQ says the exam takes 2¼ hours including instructions and exam time. Older online references may still describe the pre-2025 version that included the CLOZE section.
Be careful. The CLOZE section was removed effective January 1, 2025, so older guides may describe a test format that is no longer current.
Check the retest rules for the exact test and department. A failed written exam does not mean you can never become a police officer, but you may have to wait before retesting or before applying again.
The police written exam is not about proving you already know how to be a cop. It is an early screening tool that measures skills departments expect you to bring into training—especially reading, writing, observation, judgment and the ability to communicate clearly.
Find the exact test used by your department, use the official preparation material, and practice the skills that test actually measures.
