Private Investigator Practice Test 2026 — Free Private Investigator Exam Prep Questions
Most states require anyone who wants to be licensed as a private investigator, or to run an agency, to pass a written exam on investigative law, practice and ethics. Our practice follows the California BSIS private investigator exam outline, with questions on federal privacy laws (FCRA, GLBA, DPPA, wiretap rules), surveillance, evidence, report writing and professional conduct that come up on most state exams.
A plaintiff's attorney asks an investigator to interview witnesses for a pending lawsuit. Why is it usually preferable for the engagement agreement to be signed with the attorney and to state that the work is at counsel's direction?
