Do you want to become a Private Investigator?



Are you a licensed Private Investigator but lacking real skills?



Would you like to learn to be a Private Investigator and be taught by true industry leaders?

The Investigative Collective delivers professional development courses including:

  • Advanced surveillance skills;
  • Interviewing witnesses and suspects; and
  • Advanced writing skills – statements and reports.

Our courses have been developed, and are delivered, by experienced professionals with extensive investigation and surveillance experience and qualifications. These three types of private investigator training courses can be done individually or as a package at a discounted rate.

Through our associations with many operational private investigation firms we have identified the skills and knowledge NOT TAUGHT by the accredited licensing courses taught at most other investigative training institutions.  We deliver REAL training in the field with REAL private investigators – this is a skills based course involving action not words.

The Investigative Collective provides a mix of experience, innovation, knowledge and skill through its experienced trainers, including:

He runs the six investigation agencies on a day to day basis and lives the life that the industry can provide to the right people.
