If you want to start a career as a private investigator, getting certified can help. It shows you have training, skills, and the right mindset. It can also help you get more jobs. In this guide, you will learn how to become a certified private investigator in the United States.
What Certification Means
Private investigator certification is different from a PI license. A license is required in most states. Certification is extra training that proves your knowledge. It helps you look more professional to clients and employers.
License vs. Certification
A license gives you legal permission to work as a PI.
A certification shows you have completed special training.
Most people get the license first and then earn a certification, but you can work on both at the same time.
