Cognitive Ability Test

The Cognitive section is composed of six ability assessments:

  • Written Expression
  • Written Comprehension
  • Problem Sensitivity
  • Deductive Reasoning 
  • Inductive Reasoning
  • Information Ordering

Answer the easier questions first; then go back and answer the harder items. There are 48 questions in the Cognitive section, with a recommended time limit of 1 hour and 40 minutes. It is best to answer every question; guess if necessary.

On the Cognitive Test, you will encounter many short passages, each followed by one or more questions. Four possible responses follow each question. Read every question carefully before marking your answer.

Written Expression– Two basic types of questions are included in the Written Expression portion of the Ability Test:

  • Determine the most appropriate way to express an idea. The response that you choose will represent the original idea and reflect that idea more clearly and concisely than the remaining three alternatives.
  • Your task is to choose the logical order of action/sentences. Police Incident Reports are often used as the focus of passages.

Reading Comprehension– This portion is often referred to as Written Comprehension. Several moderately long passages, each followed by one or more questions, are included within the Reading Comprehension portion. In order to focus in on the subject matter of the questions, read the questions before reading the passage.

Problem Sensitivity– Your ability to identify the existence of problems is assessed in this portion of the test. There are two basic question sources covered:

  • Witness accounts are presented. You will pick the account that significantly differs from the statements of the other witnesses.
  • A set of rules are followed by the description of a situation. The task is to choose the most problematic manner of responding to the incident.

Deductive Reasoning– This type of reasoning is characterized by utilizing a general rule or law to determine the classification of specifics. The exam provides several case classifications. The requirement is to determine the classification of the case presented.

Inductive Reasoning– Given various particulars, the task is to decipher the rule. To find the correct answer, focus on common elements. Many questions contain the description of the suspects in various crimes. Finding the substantial commonality and differences in the descriptions, lead to a determination as to which crimes a particular defendant is suspected of committing.

Information Ordering– Sequencing information appropriately is the object of this assessment.

Work Styles Questionnaire (WSQ)

This section of the exam is practically a personality assessment test. It assesses your work goals, teamwork, leadership propensity, sensitivity to negative remarks and decision-making ability. You will read a statement, then select the rating that most closely reflects your views. There are five ratings to choose from: Strongly Disagree (1) through Strongly Agree (5). It is essential that you answer every question in this section of the Suffolk Police test.

Life Experience Survey (LES)

In the LES section, you will encounter a wide range of topics. Each question is followed by five alternatives. The job is to pick the response that best describes you and your past experiences. The assessments contained in LES concern characteristics such as work ethic and community-based involvement. You are required to answer every question in the Life Experience Survey section.

Who takes the Suffolk Police test?

Applicants for the positions of Police Officer and Police Officer (Spanish Speaking) are the test-takers. The written exam is in English, and it is the same test for both job titles. A subsequent Spanish oral language proficiency test is given to Spanish Speaking candidates who pass the written exam. Those who fail the oral proficiency test will remain on the eligibility list for the Police Officer position. 


Each section is scored separately, and the three scores are combined to formulate the test result. Applicants must pass the Suffolk County PD Exam in order to be placed on the eligibility list for officer vacancies. The “pass” threshold is 70.

LEAB Test Sample Questions

The EB Jacobs Law Enforcement Aptitude Battery (LEAB) contains an ability test and a work style questionnaire. See below for sample questions you may face: 

Inductive reasoning



In order to calculate the percentage of participants who felt the conference contributed to their knowledge, we must first calculate the total number of people who attended a conference on Wednesday:

Total number of people on Wednesday: 100+150+75+200= 525

Now we can calculate the relative amount of 315 out of 525: 315/525= 0.6= 60%

Paragraph organization




D – Represents the best-organized paragraph. Looking at the options you can determine that your introduction sentence is either 1 or 3. Sentence 1 is very general – it presents a subject, not yet discussing it. Sentence 3 has a lot of information, it is a support sentence. Once you determine that sentence 1 is a better introduction you can eliminate options A and C, leaving you with options B and D. In this situation, when you have already identified the introduction sentence, it is sometimes to easier to try to find the closing sentence next. Remember the closing sentence should not be introducing new ideas or supporting new ideas, it should only be summarizing what was stated in the paragraph.

In this case, the only two options you have closing sentence is 2 and 4. If you read sentence 2 and 4 closely, you can see that sentence 2 gives additional information while sentence 4 is a conclusion, summarizing what was stated in the previous sentences. Remember a great paragraph introduces the idea (introduction sentences) then has 2-3 supporting the idea (supporting sentences) and then summarizes the information given (closing sentence).

Arranged correctly it should read:

Social workers interact with a wide range of populations. Their patients may include families of physically and mentally handicapped, children at risk or the elderly. These patients can be seen in their homes, schools, hospitals or drug rehabilitation centers. The demand for social workers is very high, unfortunately, because of budget cuts, many positions for social workers are not being filled at this time.

Deductive reasoning

(Read the RULE carefully and answer the question)

When property is sold by means of a vending machine, the owner of the property being sold is the retailer and as such is responsible for sales tax on the entire gross receipts thereafter, regardless of how such receipts are divided.



The correct answer is (A).

The 13 products are being sold by means of a vending machine. The owner of these products is Conway. Therefore, he is responsible for the sales tax on them. – "When property is sold by means of a vending machine, the owner of the property being sold […] is responsible for sales tax on the entire gross receipts therefrom regardless […]"

Also, it does not matter whether the receipts are divided. – "[…] regardless of how such receipts are divided."
