Our History:  Police Legal Sciences, Inc. (PLS) was founded in 1999 by attorney Gerald N. Partridge. PLS began by providing state-specific legal update training to law enforcement officers in Missouri and Iowa. 

In 2008, PLS began producing online reality-based dispatcher training. Now, dispatchers at PSAPs in 39 states and Canada take these lessons each month. The sizes of subscribing PSAPs range from three to hundreds and include sheriff’s offices, city police departments, county and consolidated PSAPs, state patrols, park rangers, airport dispatchers, campus police departments, privatized PSAPs, Native American reservations, and federal agencies (military bases, NASA, etc.).

In 2020, PLS developed reality-based, online training specifically designed for jail officials (correctional officers, jail supervisors, sheriffs, and medical and mental health staff).

Our Mission:  Our mission is to help public safety professionals make good decisions.

The PLS Difference:  PLS's reality-based training is based on actual 9-1-1 calls and the facts of actual court cases, used to approximate the situations law enforcement officers, correctional officers, and 9-1-1 emergency face in operational settings. This reality-based approach promotes understanding of how to apply the law in a variety of situations, appreciation of the legal and financial consequences of decisions, mental sharpness, situational awareness, and confidence.
