I live in San Antonio. Here, you are allow to apply after two years of service. This is an extremely competitive examination. Officers will often take vacation time so they can study. If you are caught studying while at work you can get in trouble. Officers in smaller towns tend to do more of their own investigative work, at least on the smaller cases. However, smaller towns often do not pay as much as the larger cities.

Hi Ignacio,

This is not my field but I did have a relationship with FBI recruiters when I worked in career services and had the opportunity to visit their offices in Miami which was pretty cool! I found a link to an article that might answer your question: https://www.howtobecome.com/how-to-become-a-detective. It says it "Becoming a police officer requires about six months of training, and officers must typically gain four or five years or experience before they can take a promotional exam to become a detective. Some police departments allow officers to substitute a college degree for a year of experience". I think this also depends on what type of detective you want to become and for what agency. I want to say it may take more time depending on the level of expertise you are looking to attain. Hope this helps!
