The POST Path
Becoming a reserve officer in California
Volunteering as a sworn peace officer with a local department runs through the state's POST system. Here's your roadmap to service.
01
Meet Baseline Requirements
You must be at least 18 (most agencies require 21), a U.S. citizen or permanent resident, have a high school diploma or GED, and a valid CA driver's license. No firearm-barring convictions allowed.
02
Choose an Agency & Apply
Check websites for agencies like SFPD, Oakland PD, or San Mateo Sheriff. The process mirrors full-time hiring: written exam, physical agility, interviews, background check, polygraph, and medical/psych evaluations.

Complete POST Reserve Training
Level III
