Institute for Criminal Investigation Core Course

The Robert Presley Institute of Criminal Investigation (ICI) Core Course is the prerequisite for all subsequent ICI Foundation Specialty Courses. It is designed to enhance the effectiveness of the individual criminal investigators skills in performing the multi-disciplined, multi-leveled tasks necessary to successfully conduct comprehensive criminal investigations. Instruction in this course is provided through a coordinated, experience-based adult learning approach which addresses crime scene management, interviewing and interrogation skills, search and seizure issues, search warrant preparation, surveillance techniques, case reporting, informant management, and courtroom testimony.

Mandatory Prerequisite: Search Warrant Fundamentals (accessible online via POST Learning Portal).

Students are required to bring a laptop for this course.

All attendees must be actively employed by a POST-participating Law Enforcement Agency. Priority will be given to those assigned to a detective role or will be assigned to a detective role within six months. Other sworn/non-sworn personnel may attend ICI on a space available basis.
