1Trooper Larson works 5 days a week and issues an average of 6 traffic citations per day. How many citations does he issue in a 4-week period (assuming a standard 5-day work week)?
A.120
B.100
C.90
D.150
Explanation: Multiply the daily rate by days worked: 6 citations x 5 days = 30 per week. Over 4 weeks, 30 x 4 = 120 citations. Breaking a word problem into weekly totals first avoids errors.
2In a burglary report, Trooper Conner listed the following stolen items: gaming console $600, tablet $325, phone $250, and a barcode scanner $85. What was the total value of all the stolen goods?
A.$1,260
B.$1,360
C.$1,160
D.$1,200
Explanation: Add all four values: 600 + 325 + 250 + 85 = 1,260. Careful column addition is essential because no calculator is permitted on the POST math section.
3Using the stolen items list (console $600, tablet $325, phone $250, scanner $85; total $1,260), what percentage of the total value does the tablet represent? Round to the nearest whole percent.
A.26%
B.20%
C.15%
D.30%
Explanation: Divide the part by the whole and multiply by 100: 325 / 1,260 = 0.2579, which is about 26%. Percentage-of-total questions are common on the POST and require dividing the item value by the grand total.
4During a 7-day period, Detective Singh received 150 tips on an investigation. If he received 60 tips on the first day, what was the average number of tips he received on each of the remaining 6 days?
A.15 tips
B.12 tips
C.20 tips
D.10 tips
Explanation: Subtract the first day, then divide by the remaining days: 150 - 60 = 90 tips over 6 days, and 90 / 6 = 15 tips per day. Always remove the fixed amount before computing the average of what remains.
5Trooper Steele issued 40 traffic citations in one month with a total fine value of $4,800. What is the average fine amount per citation?
A.$120
B.$150
C.$100
D.$240
Explanation: Average equals total divided by count: $4,800 / 40 = $120 per citation. This is a straightforward division problem typical of the POST arithmetic section.
6A patrol vehicle travels 270 miles on a shift and uses 18 gallons of fuel. What is the vehicle's fuel efficiency in miles per gallon?
A.15 mpg
B.12 mpg
C.18 mpg
D.20 mpg
Explanation: Miles per gallon equals miles divided by gallons: 270 / 18 = 15 mpg. Rate problems ask you to divide the total distance by the total fuel used.
7A trooper begins a shift with a full 20-gallon fuel tank. After patrol the tank is at 1/4 full. How many gallons of fuel were used during the shift?
A.15 gallons
B.5 gallons
C.10 gallons
D.16 gallons
Explanation: A quarter tank remaining means 1/4 x 20 = 5 gallons left, so 20 - 5 = 15 gallons were used. Convert the fraction to gallons first, then subtract from the full amount.
8An accident report states that a collision occurred at 2:45 PM and the road was cleared at 4:20 PM. How long was the road affected?
A.1 hour 35 minutes
B.1 hour 25 minutes
C.2 hours 35 minutes
D.1 hour 45 minutes
Explanation: From 2:45 to 4:45 is 2 hours, but the road cleared at 4:20, which is 25 minutes earlier; 2 hours minus 25 minutes equals 1 hour 35 minutes. Alternatively, 2:45 to 3:45 is 1 hour, plus 35 more minutes to 4:20.
9A trooper must inventory 480 evidence items into boxes that hold 40 items each. How many boxes are needed?
A.12
B.10
C.14
D.16
Explanation: Divide the total items by the box capacity: 480 / 40 = 12 boxes. Division problems like this test whether you can break a large total into equal groups without a calculator.
10A speed limit is 55 mph. A driver is clocked traveling 72 mph. By how many miles per hour is the driver exceeding the limit?
A.17 mph
B.27 mph
C.13 mph
D.18 mph
Explanation: Subtract the limit from the measured speed: 72 - 55 = 17 mph over the limit. Simple subtraction is the foundation of many POST math items.

OSP Trooper Exam Study Tips from Top Performers

1Drill no-calculator arithmetic daily — long division, fractions, percentages, averages, and rates — because the math section bars calculators and is the first section you face.
2Read police-context passages and practice locating exact facts, then answer detail, inference, and sequencing questions by referring back to the text.
3Review high-frequency spelling words (receive, accidental, occurrence, separate, definitely) and the ie/ei and double-consonant rules for the grammar section.
4Master commonly confused words such as affect/effect, their/there/they're, fewer/less, and between/among, which appear in word-usage items.
5For incident report writing, turn report-form facts into complete sentences with correct spelling, grammar, and punctuation, and never add opinions or conclusions.
6Practice under each section's strict time limit so you can pace yourself and guess rather than stall, since there is no penalty for guessing.
7Begin OSP Physical Fitness Test preparation early — the academic exam is only one part of the same Entry-Level Testing day.

Frequently Asked Questions

What is the Oregon State Police trooper academic exam?

It is the written academic portion of Oregon State Police Entry-Level Testing (ELT) for recruit trooper applicants. The academic exam is the National Police Officer Selection Test (POST), which covers mathematics, reading comprehension, grammar, and incident report writing at a high-school-equivalency level.

What sections are on the exam and how many questions are there?

There are four timed sections. Per the OSP familiarization guide, math has 20 questions in 30 minutes, reading comprehension has 25 questions in 25 minutes, grammar has 20 questions in 15 minutes, and incident report writing has 10 questions in 15 minutes — 75 items in total.

Who administers the exam?

Oregon State Police administers Entry-Level Testing in person at locations posted during open recruitment. The academic exam itself is the National POST published by Stanard & Associates, the entry-level selection test used by many law enforcement agencies.

Can I use a calculator on the math section?

No. The OSP guide states calculators are not allowed, so you must add, subtract, multiply, and divide (including long division) and work with fractions and percentages by hand. Scratch paper is provided for the math section.

What score do I need to pass?

A score of 70% is the standard passing mark for the National POST and is widely used for entry-level law enforcement. Oregon State Police does not publish a single combined cut score, so prepare to score well above the minimum to remain competitive.

Do I need prior law enforcement knowledge?

No. Although most questions are set in a police context, the OSP guide states that no prior knowledge of laws or law enforcement is needed. The exam measures basic reading, writing, and arithmetic skills.

Can I retake the exam?

Retakes occur on the next open OSP recruitment cycle. Some agencies that use the POST enforce a no-retest policy within a single cycle, so candidates should aim to pass on the first attempt and apply again when recruitment reopens.

What else happens during Entry-Level Testing?

ELT has three parts: the OSP Physical Fitness Test, the academic exam, and step one of the psychological evaluation. Plan to dedicate a full day to ELT, after which steps such as the command interview, background investigation, and medical screening follow.
