Law Enforcement Aptitude Battery (LEAB)

Assesses a variety of underlying characteristics important in the performance of the duties and responsibilities of law enforcement officers

The Law Enforcement Aptitude Battery (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 LEAB was developed 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:

Candidates’ scores are based on the three assessment devices comprising the LEAB.  The normative group used to create LEAB scores is PSI’s 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.
