Entry Level Selection
EB Jacobs offers comprehensive entry level testing services for all law enforcement officer assignments in Federal, State, municipal, and county agencies.  The EB Jacobs approach to entry level selection embraces the value of cognitive ability tests but recognizes that personal characteristics and work styles also play a large role in performance effectiveness.  The EB Jacobs flagship product borne out of this approach is the Law Enforcement Aptitude Battery (LEAB).  By combining cognitive ability assessment with non-cognitive measures during the initial phase of testing, we enhance the prediction of performance, while counteracting the potential adverse results of the cognitive test by including other job related assessments that have less adverse impact on protected groups.  As a result, the group of law enforcement officer candidates that moves forward into subsequent phases of assessment is much more diverse than would normally be the case with traditional law enforcement selection tests.

Law Enforcement Aptitude Battery (LEAB)
The LEAB is a set of assessment instruments covering three basic areas: cognitive abilities, approaches to work or what we refer to as personal workstyle, and background information or biodata.  Each instrument is matched to job requirements and each assesses a variety of underlying characteristics important in the performance of the duties and responsibilities of law enforcement officers.

 * The candidate database contains percentages of individuals within each racial/ethnic and gender subgroup representative of the levels expected in the populations of large metropolitan areas.

The LEAB was developed by EB Jacobs based on 10 years of research with dozens of law enforcement agencies.  We have collected data from over 15,000 candidates and created a database for evaluating our results with a sample in excess of 1,100 incumbent law enforcement officers in State, municipal, and county law enforcement agencies.  The LEAB will help you:

  • Select the best candidates who are most able and willing to do the job.
  • Increase diversity by minimizing adverse impact.
  • Maximize test standardization and fairness for all candidates.
  • Reduce time and cost of testing.
  • Enhance test security with multiple versions.

The LEAB is available in two administrative formats, using a traditional paper and pencil method or through our online testing service.  The features of each option include:

  • Preparation Guide
  • Preparation Guide
  • Administrator Manual
  • Administrator Manual
  • Parallel Versions
  • Parallel Versions
  • Sample Oral Administration Instructions
  • User Set-Up

  • Candidate Demographic & Background Info.
  • Computer Scoring
  • Immediate Scoring and Results
  • Hand-Scoring to Verify Computer Scores
  • Electronic Score Notices Sent to Users
  • Reporting and Statistical Analysis
  • Maintenance of Candidate Database
  • Candidates’ scores are based on the three assessment devices comprising the LEAB.  The normative group used to create LEAB scores is EB Jacobs’ candidate database of law enforcement officers.  Therefore, a candidate’s LEAB result can be compared to thousands of candidates nationwide making it a strong benchmark for understanding the relative capabilities of your agency’s applicants. In addition to overall scores, our standard output includes a flag that identifies candidates who may not possess minimal qualifications with respect to cognitive ability.

    Prior to using the LEAB, a targeted and focused amount of job analysis data is collected to demonstrate that the job in your agency is similar to the jobs in the agencies on which we have validated the LEAB.  The goal is to show that the requisite abilities and characteristics in your agency match those of the agencies on which we have validated the LEAB.  Once a job match is achieved the validity evidence derived in the validation agencies can be transported to your agency.  This step is very important to professionally and legally support that the LEAB is appropriate and valid for use in your agency.

    Oral Assessments
    Expressing thoughts clearly and understanding information presented orally are abilities that are critical to the effective performance of law enforcement officers.  EB Jacobs offers oral exercises that simulate situations new recruits are likely to encounter as well as generic structured interview manuals.  These exercises measure verbal and reasoning skills required to perform the law enforcement officer’s job effectively.  Although the work sample exercises include law enforcement content, they do not require any previous knowledge of law enforcement practice or policies.  Several forms of the exercises exist that vary in length of time required for administration.  These exercises can be used either during the initial phase of written testing as a screening device or during subsequent phases of testing as a complement to other test components.  Trained assessors observe and evaluate candidate performance on the verbal and reasoning skills necessary to perform the law enforcement officer’s job.
    Candidate Preparation
    Providing information regarding the content and logistics of each examination component helps ensure that all candidates are on equal footing when they take the examination, thereby representing an effective step toward the reduction of adverse impact.  Our recommended program includes a detailed description of the examination content and logistics, strategies that candidates can use to enhance examination performance, and sample items.  We feel so strongly about candidate preparation that a self-paced Candidate Preparation Guide is a standard element of all of our testing processes.
    Test Administration Services

    Efficiency, security and standardization are the primary test administration goals EB Jacobs will help you achieve.  EB Jacobs staff will work closely with your agency to develop the most efficient administrative system to best meet your needs.  We will provide you with an administrative manual, train test administrators and monitors, and supervise or assist in the administration as desired.
