Texas Investigator Institute (TII) is dedicated to become a leading provider of private investigator training in Texas, delivering state-approved, up-to-date investigative courses for both new and experienced PIs. TII was built on the belief that modern investigators deserve real-world, relevant, and cutting-edge instruction—not the outdated material still used by many other schools.

​

With decades of hands-on experience in surveillance, undercover operations, insurance fraud investigations, digital forensics, and criminal defense support, veteran investigator, current owner and manager, Chris Monroe has developed a curriculum that blends practical investigative skills with current Texas laws, administrative code requirements, and modern investigative technology. Whether you are working toward your Texas private investigator license, seeking continuing education hours to maintain certification, or upgrading your surveillance and case management skills, TII provides industry-relevant, scenario-based training that keeps you ahead of the competition.

​

Unlike other investigator training programs that rely on recycled case studies and outdated investigative tactics, our courses are updated regularly to reflect new laws, evolving technology, and emerging investigative trends. Every class is designed to ensure you leave with the skills and knowledge to succeed on real cases—from field surveillance in complex environments to digital intelligence gathering that meets court admissibility standards.

At Texas Investigator Institute, you’re not just learning to pass a test—you’re training to excel in the field.
