Investigative Services study plan

Investigative Services · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Investigative Process and Case Management

  • Map the full investigative lifecycle from intake to case closure into a one-page flow you can redraw from memory

  • Draft a case-management checklist covering triage, prioritization, task assignment, and documentation cadence

  • Write 15 original practice items on investigative process and case management, then log why each wrong option is wrong

  • Define how you will track weak areas across all nine domains for the rest of the plan

Your checkpoint

A one-page lifecycle diagram plus a 15-item self-written quiz with a scored answer key

Week 2

Investigative Process and Case Management & Legal and Regulatory Framework

  • Apply case-management concepts to three hypothetical scenarios and justify each prioritization decision in writing

  • Summarize the legal and regulatory framework into a comparison table of authority sources, privacy limits, and evidentiary rules

  • Identify where legal constraints change investigative procedure and note the decision points

  • Complete 20 mixed practice items across domains 1 and 2 and record error categories

Your checkpoint

A two-column legal-constraint table mapping procedures to the rules that govern them

Week 3

Interviewing and Interrogation & Evidence Collection, Handling, and Chain of Custody

  • Outline a structured interview plan including rapport building, questioning sequence, and documentation

  • Compare interviewing and interrogation approaches and state when each is appropriate and lawful

  • Build a chain-of-custody form and walk one item of evidence through collection, packaging, transfer, and storage

  • List common evidence-handling errors and the control that prevents each

Your checkpoint

A completed sample chain-of-custody packet for one simulated evidence item, from seizure to final disposition

Week 4

Interviewing and Interrogation & Evidence Collection, Handling, and Chain of Custody

  • Draft and rehearse a 10-minute mock interview script with a witness and a separate suspect version

  • Critique your own script against recognized pitfalls such as leading questions and contamination

  • Produce a written evidence-handling procedure with acceptance criteria for each step

  • Complete 25 practice items across domains 3 and 4 and re-test every earlier missed item

Your checkpoint

A mock interview transcript with a written self-critique identifying at least five improvement points

Week 5

Surveillance and Covert Operations & Forensic Science and Technology

  • Design a surveillance plan covering objectives, legal authorization, cover, communications, and contingency withdrawal

  • Explain the limits of covert methods and document where authorization is required

  • Match forensic disciplines to the evidence types they serve and note collection requirements for each

  • Describe how digital and physical forensic findings are documented and preserved for later use

Your checkpoint

A surveillance operations plan plus a forensic-discipline-to-evidence matching matrix

Week 6

Fraud, Financial, and Cyber Investigation

  • Trace a fraud scheme from red flag to evidence trail using a constructed financial scenario

  • Outline the steps of a cyber incident investigation from detection through containment and reporting

  • Identify the records and data sources you would request in a financial and a cyber case

  • Complete 25 practice items on fraud, financial, and cyber investigation and log recurring error patterns

Your checkpoint

A written case walkthrough of one fraud or cyber scenario with an evidence-request list and analysis timeline

Week 7

Report Writing, Testimony, and Ethics & Safety, Risk Management, and Professional Conduct

  • Draft an investigative report using a clear structure of summary, findings, evidence, and conclusions

  • Prepare and rehearse direct and cross-examination answers for a mock testimony session

  • Apply an ethics decision framework to three ambiguous scenarios and justify each conclusion

  • Build a safety and risk-management checklist covering fieldwork hazards and escalation triggers

Your checkpoint

A complete mock investigative report plus a 5-minute recorded testimony rehearsal

Week 8

Investigative Process and Case Management & Legal and Regulatory Framework & Interviewing and Interrogation & Evidence Collection, Handling, and Chain of Custody & Surveillance and Covert Operations & Forensic Science and Technology & Fraud, Financial, and Cyber Investigation & Report Writing, Testimony, and Ethics & Safety, Risk Management, and Professional Conduct

  • Re-test every previously missed item and confirm each is now answered correctly with reasoning

  • Take two timed full-length practice exams and compare domain-level scores

  • Review the two weakest domains using your own notes and checklists only

  • Finalize a one-page pre-exam reference sheet of decision rules and definitions

Your checkpoint

A scored two-exam results log with a written remediation note for every remaining weak area

Milestones
