State private investigator licensing boards administer written examinations that test your knowledge of PI laws, investigative techniques, surveillance procedures, and professional ethics. Our free printable PDF gives you realistic practice questions you can study anywhere — no internet required. Download it once and review it as many times as you need before your licensing exam.
Private investigator licensing requirements vary by state, but most written exams cover a consistent set of core competencies: legal authority and limitations, surveillance methods, records research and skip tracing, interview techniques, report writing, and evidence handling. The PDF covers all of these areas so you can identify weak spots and focus your review time effectively.
A core exam topic is understanding exactly what a PI is and is not legally authorized to do. Unlike law enforcement, private investigators have no arrest authority and are bound by the same trespass laws as any private citizen. Exams test knowledge of public versus private property rules, the legality of pretext interviews, and prohibited activities including impersonating law enforcement officers, illegal wiretapping, unauthorized computer access under the CFAA, and conduct that could constitute stalking. The Fourth Amendment restricts government actors — PIs operating as private parties face different, but still significant, legal boundaries.
Surveillance questions cover both stationary and mobile methods. Stationary surveillance tests vehicle selection, positioning strategy, and maintaining a believable cover story. Mobile surveillance questions address following a subject on foot and by vehicle without detection. Electronic surveillance is a heavily tested area: recording laws differ by state, with one-party consent states allowing recording by a participant to a conversation and two-party (all-party) consent states requiring consent from all parties. Photography in public places is generally protected, but exams test the nuances. Social media investigation through open-source intelligence (OSINT) is increasingly tested as well.
PIs use a wide range of public records: court records, property records, voter registration, business filings, UCC filings, and vital records including birth, marriage, death, and divorce documents. Motor vehicle records are heavily restricted by the Driver Privacy Protection Act (DPPA) — exams test which permissible purposes allow DMV record access. Skip tracing methods include public databases, social media, and utility connection records. When conducting consumer background checks, the Fair Credit Reporting Act (FCRA) imposes additional compliance requirements.
Exams cover voluntary versus compelled interviews, basic tenets of the Reid Technique versus the cognitive interview approach, and how to document interviews through notes and recordings. Report writing questions emphasize objective versus subjective language, chronological narrative format, photographic evidence documentation, chain of custody procedures, and preparing court-ready reports and affidavits that will withstand scrutiny from attorneys and judges.
