Trooper Selection Process Description

The Pre-Employment testing portion of the Trooper Selection Process is comprised of several phases, including a written examination, a physical fitness for duty assessment, polygraph examination, background investigation, oral interview board, medical examination, drug screening, and a psychological examination and interview. You are expected to complete each phase of the selection process to be considered for employment.

After each testing phase, you will receive notification of your status. Due to this, it is imperative the Human Resources Division has a current mailing address and telephone number on file for you. You are responsible for immediately notifying Human Resources of any address or telephone number change. All individuals are notified of their status and informed of the application procedures for future testing periods.

An explanation of each phase of the selection process is listed below:

Written Examination

The National Criminal Justice Officer Selection Inventory (NCJOSI2) consists of a series of multiple-choice questions, true-false questions and rating scales designed to test important cognitive abilities and personality attributes that are necessary for effective job performance as a criminal justice officer.

In developing the NCJOSI2, a group of law enforcement experts from criminal justice agencies throughout the United States identified many of the tasks essential to the performance of the job of a criminal justice officer. From these tasks, essential areas for entry-level testing were determined. These areas are as follows:

  • Problem Solving Ability
  • Reading Comprehension
  • Personality Characteristics
  • Writing Ability

The test areas have been clustered or grouped into two sections on the NCJOSI2. The cognitive section, which includes problem solving, reading comprehension, and writing ability is the first part of the exam. Various attitudes and personality characteristics are clustered together to form the second section of the NCJOSI2. The total time allowed for taking the NCJOSI2 is two-and-a-half (2 1/2) hours.

Fitness for Duty Assessment

This phase consists of five events: push-ups, trigger pull, sit-ups, 300 meter run, and 1.5 mile run. (Click for the instructions for each event.) The events will be scored individually as a pass/fail. Failure of an event will result in disqualification for that particular selection process, and the applicant will not be allowed to participate in the remaining events. Applicants will not be allowed to retest, but may reapply for the next selection process, if eligible.

The fitness battery and its pass/fail thresholds are based on normative data gathered by the Cooper Institute in Dallas, Texas. The Cooper Institute's normative data provide substantial evidence that both the exercises and pass/fail thresholds used in the fitness test are appropriate for law enforcement jobs.

Polygraph Examinations

The applicant must undergo a polygraph examination, administered by a Patrol polygraphist. The examination is used to assist the background investigator in conducting a comprehensive investigation of an applicant. The main recording in the polygraph examination is blood pressure. The polygraph examination can be stressful for some applicants. Conditions such as hypertension, pregnancy, respiratory or heart ailments, etc., may affect the results of the polygraph examination. While there is no medical evidence that a polygraph examination effects a person's health, applicants are encouraged to discuss this step with their physician prior to the examination to determine if they are able to be tested. If an accommodation is needed, the applicant must discuss that with the Human Resources Division at the time the examination is scheduled. Those applicants who are pregnant will not be tested until after the birth of the child. All applicants are required to sign a waiver form prior to taking the polygraph examination. The areas covered in the polygraph examination are as follows:

  • Employment History
  • Traffic Record
  • Financial History
  • Current Illegal Drug Usage
  • Record of Criminal Convictions
  • Basic Honesty

Information obtained through the background investigation is held strictly confidential. To assist the background investigator, applicants are required to obtain a standard list of documents, such as:

  • Certified copy of birth certificate obtained from the birth states' Department of Health (an original birth certificate, photocopy of the original or certified copy, or a notarized copy are NOT acceptable)

Background Review and Structured Oral Interview Board

Each applicant's background investigation is submitted to a board comprised of uniformed members who evaluate the information presented and assess the applicant's suitability for the position. Independent of the background investigation assessment, the applicant will participate in a structured oral interview. During the interview, the interview board will rate the applicant's oral communication skills and responses to questions in predetermined dimensions.
