Course FAQs

more information

How do I become licensed as a PI in Texas?

Individual applicants apply through Texas Online Private Security (TOPS) and must meet DPS eligibility requirements, including the applicable background- check and fingerprinting requirements. A PI may submit an application before establishing company affiliation, but DPS will not issue the pocket card until the individual is affiliated with a licensed company.

Do I need to work for a licensed investigations company?

Yes. Texas DPS states that individuals performing regulated private security services must be licensed and affiliated with a company or entity licensed by the Department.

Can I open my own private investigation company after taking this course?

Completing this course does not by itself qualify someone to serve as the company representative for a Texas investigations company. DPS has separate experience, education, examination, and company-licensing requirements for company representatives.

Who is this course designed for?

This course is designed for aspiring private investigators, current private security professionals who want to expand their skills, and anyone seriously considering a career in professional investigations.

Another year wondering whether private investigation could be the right career for you.

More time putting off the training that could help you better understand the profession.

More opportunities passing by while you're still deciding where to begin.

Putting your professional momentum on hold instead of keeping your credentials current and your career moving forward.

Watching others move forward while you keep telling yourself you'll start later.
