Worked examples: how to reason through California POST Test questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: Which sentence uses 'affect' and 'effect' correctly? A) The new policy will effect how officers file reports. B) The arrest had a lasting affect on the community. C) Stress can affect an officer's decision-making. D) The medication had no affect on the suspect's behavior.

1. The new policy will effect how officers file reports.
2. The arrest had a lasting affect on the community.
3. Stress can affect an officer's decision-making.
4. The medication had no affect on the suspect's behavior.

Answer: C. Stress can affect an officer's decision-making.

Explanation:

Option C is correct because 'affect' is used as a verb meaning to influence: stress influences an officer's decision-making. Option A uses 'effect' as a verb, which means to bring about, so the sentence says the policy will create how officers file reports, which is not the intended meaning. Option B needs the noun 'effect', since something that lasts is a result. Option D also needs the noun, because 'no effect' names a result.

Rule to remember: 'affect' is usually the verb, 'effect' is usually the noun. Try swapping in 'influence' for a verb or 'result' for a noun. If the swap works, you have the right word.

Example 2

Question: A report states that incidents increased from 200 last year to 250 this year. What is the percentage increase?

1. 20%
2. 25%
3. 30%
4. 35%

Answer: B. 25%

Explanation:

Option B, 25%, is correct. Percentage increase is the change divided by the starting value. The change is 250 minus 200, which is 50, and 50 divided by 200, times 100, gives 25%. Option A, 20%, comes from dividing the change by the new figure, 250, instead of the original. That is the most common slip. Options C and D, 30% and 35%, have no calculation behind them and are there to look plausible if you only estimate.

Rule to remember: percentage change always uses the starting value as the base. Work out the difference first, then divide by where you began.

Example 3

Question: A crime scene is rectangular, measuring 15 feet by 22 feet. What is its area in square feet?

1. 300 sq ft
2. 310 sq ft
3. 320 sq ft
4. 330 sq ft

Answer: D. 330 sq ft

Explanation:

Option D, 330 sq ft, is correct. The area of a rectangle is length times width, and 15 multiplied by 22 equals 330. Options A, B and C are close in size, which is what you get from small slips in multiplying or from rounding a side before you calculate. They are designed to tempt you if you estimate instead of working the product through. Adding the sides would give a perimeter, not an area, so it answers a different question.

Rule to remember: area means multiplying two sides and is stated in square units. Do the multiplication in full, then check that your answer is in the right units.

How to use these practice tests

Start with the official material. Read the POST applicant preparation guide and the applicant FAQs, and contact your agency to confirm when and where your test is held, since it is paper based and run by the agency. Then use the practice sets to find where you lose marks.

For reading, work through identifying main ideas, analyzing informational passages and drawing logical inferences. For writing, use grammar and punctuation, sentence clarity, spelling accuracy and vocabulary in context. Extra practice is also available in mathematics and situational judgment.

After each set, write down every miss and the rule behind the right answer, then redo only those questions a few days later. Because the exam is on paper, practise with a pencil and a printed page, and keep to a steady pace rather than rushing. Treat our questions as practice written by us, not as real exam items. In the last days before the test, review your error notes instead of starting new topics.
