Where should i start? Ive looked up things on what to do but what is the first step? Do i just obtain an application from any police department? Do they tell me what to do after if they accept my application? How do i know the requirments of each police station?

You should visit the websites of the police departments that you are interested in. Police department websites usually provide information about their hiring process. The first step is often completing an application. Check out http://www.peaceofficerjobs.com/become-a-police-officer.html for some great information. If a department doesn't have a website or the information you want isn't provided, just call the department, and ask.

Call the department
