  • Outline the flow of a Missouri private investigator case from client intake through final report, listing the decision point at each stage

  • Draft a weekly study calendar that reserves two fixed 90-minute blocks for domain 1 and one for domain 2

  • Explain how to plan and document a stationary surveillance shift, including time logs, relief handoffs, and photo/video indexing

  • Differentiate reasonable suspicion, probable cause, and mere hunch, and give a Missouri-relevant example of each

  • Identify the limits of a private investigator's authority compared with sworn law enforcement in a given scenario

Your checkpoint

A written surveillance plan for a hypothetical missing-person case, including a shift schedule and evidence-index template

Week 4

Missouri Statutes and Board Rules

  • Summarize the Missouri board rules on continuing education, license renewal, and reporting obligations

Week 5

Evidence, Reporting, and Case Documentation

  • Design a chain-of-custody form that captures collection time, collector, storage, and transfer signatures

A complete sample investigative report of 800-1,200 words built from field notes you create

Week 6

Evidence, Reporting, and Case Documentation & Professional Ethics and Business Conduct

  • Draft a client engagement letter that defines scope, fees, confidentiality, and the limits of what you can promise

  • Identify conflicts of interest in three scenarios and state the disclosure or withdrawal step required

  • Apply record-retention and client-file confidentiality principles to a request for case files from a former client

Week 7

Professional Ethics and Business Conduct & Missouri Statutes and Board Rules

  • Write a one-page exam-day plan covering timing per question, flagging strategy, and review order

Your checkpoint

A domain-by-domain score report from the practice set plus a one-page exam-day plan
