The Professional Certified Investigator (PCI) is ASIS International's board certification for investigations. It validates experience in case management, evidence collection, and the preparation of reports and testimony. It suits corporate investigators, fraud and loss-prevention investigators, and security professionals whose work centres on running investigations.
Who is eligible
ASIS designs the PCI for people with three to five years of investigations experience, depending on education, including at least two years in case management. Holding the APP can reduce the experience requirement for some candidates. You also need to be employed full-time in a security-related role and agree to the ASIS Certification Code of Conduct. Confirm the exact requirements for your situation on the ASIS website.
Exam format
The PCI exam has 125 scored multiple-choice questions plus 15 unscored pre-test questions, 140 in total. The unscored questions are not identified. ASIS offers the exam at test centers and through remote proctoring.
What the exam covers
The PCI Body of Knowledge has three domains, and the weighting is uneven:
- Professional Responsibility (28%) — ethics and conflicts of interest, assessing case elements and risks, and managing investigative resources.
- Investigative Techniques and Procedures (52%) — interviews, surveillance, research, and collecting and preserving evidence.
- Case Presentation (20%) — writing reports, presenting findings and giving testimony.
Investigative techniques and procedures is more than half the exam. If you have mostly worked on one type of investigation, broaden out: expect questions on interview approaches, surveillance and evidence handling across different case types.
How to prepare
Focus on the heavy domain, but not only there. Investigative techniques drive the score, but professional responsibility questions on ethics, legal boundaries and conflicts are where experienced investigators often slip. The "best" answer is the defensible one, not the fastest.
Think about admissibility. Many evidence and procedure questions come down to whether an action would hold up later: chain of custody, proper documentation, lawful collection.
Practise writing for an audience. Case presentation questions test whether findings are objective, supported and clearly communicated. Think like the reader of your report.
Use the Body of Knowledge as your checklist. The official PCI BoK lists every task and knowledge statement the exam draws on.
