IAI CSCSA study plan

IAI CSCSA · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Crime Scene Investigation

  • Map the full CSCSA domain outline into a personal checklist of every subtopic under Crime Scene Investigation, marking each as known, shaky, or unknown

  • Define and write out the legal and procedural foundations of scene response: scene security, chain of custody, search authority, and documentation duties

  • List the sequence of first-responder actions from arrival through scene release and explain why each step protects evidence integrity

  • Build a one-page glossary of core terminology (scene integrity, contamination, transfer, control samples, reference standards) with your own definitions

Your checkpoint

A completed domain checklist with every subtopic rated and a one-page terminology glossary

Week 2

Crime Scene Investigation

  • Describe scene documentation methods in order: notes, photography, videography, sketching, and measurement, and state what each captures that the others do not

  • Practice converting a described room layout into a scaled rough sketch with a legend, orientation, and measurements

  • Explain the purpose and mechanics of chain of custody and identify where documentation commonly breaks down

  • Compare search patterns (line, grid, spiral, zone, wheel) and match each to appropriate scene types and terrain

Your checkpoint

A hand-drawn scaled scene sketch with legend plus a written chain-of-custody sample form

Week 3

Crime Scene Investigation

  • Outline evidence collection and packaging rules by category: biological, latent print, trace, digital, firearms, and questioned documents

  • Explain why packaging choices differ across evidence types and what cross-contamination risks each carries

  • Describe the roles and limits of DNA, latent print, and trace analysis in linking persons, objects, and locations

  • Identify the standard reference samples needed for comparison and when they must be collected

Your checkpoint

An evidence handling matrix covering at least eight evidence categories with collection, packaging, and preservation notes

Week 4

Crime Scene Investigation

  • Analyze bloodstain pattern categories (passive, spatter, altered) and the physical mechanisms behind each

  • Explain how impact angle, point of origin, and directionality are estimated and what limits those estimates

  • Apply the scientific method and falsification mindset to reconstruct a sequence of events from physical evidence

  • Distinguish reconstruction from speculation and write conclusions that separate observation from inference

Your checkpoint

A written reconstruction of a described scene that clearly separates observed facts, supported inferences, and open questions

Week 5

Crime Scene Investigation

  • Describe death investigation fundamentals: livor, rigor, algor, decomposition stages, and entomological indicators

  • Explain how postmortem indicators inform time-since-death estimates and where those estimates fail

  • Outline the medical examiner and coroner interface with investigators, including jurisdiction and reporting duties

  • List the categories of equivocal death and the questions investigators must resolve before ruling manner

Your checkpoint

A one-page death scene checklist linking each postmortem indicator to the question it answers and its limitations

Week 6

Crime Scene Investigation

  • Describe specialized scenes: fire and arson, explosion, shooting, sexual assault, and clandestine grave, and the distinct approach each requires

  • Explain the role of forensic anthropology and archaeology in surface scatter and buried remains recovery

  • Outline mass disaster and mass fatality response structure, including identification methods and morgue operations

  • Identify safety hazards at specialized scenes and the personal protective measures each demands

Your checkpoint

A comparison table of five specialized scene types with approach, key evidence, and safety concerns

Week 7

Crime Scene Investigation

  • Trace the full evidence lifecycle from collection through laboratory analysis to courtroom presentation and identify each handoff point

  • Explain the investigator's obligations regarding exculpatory evidence, discovery, and expert testimony preparation

  • Describe quality assurance factors: laboratory accreditation, proficiency testing, and error and bias mitigation

  • Practice explaining a technical finding to a non-technical audience in plain language

Your checkpoint

A written mock expert-witness summary of one evidence type in plain language, under 400 words

Week 8

Crime Scene Investigation

  • Re-rate every checklist item from week 1 and close the remaining unknown items with targeted review

  • Complete at least two timed practice assessments and log every missed question by subtopic

  • Rewrite weak-area notes into concise recall cards covering procedures, thresholds, and definitions

  • Assemble a final one-page rapid-review sheet of the highest-yield facts and procedures

Your checkpoint

A completed re-rated checklist, error log, and one-page rapid-review sheet

Milestones

Week 2: Produce a scaled sketch and chain-of-custody form from memory with no reference material, scoring at least 80 percent against your own rubric

Week 4: Explain bloodstain pattern mechanisms and reconstruction logic aloud without notes for ten minutes, then verify against your written summary

Week 6: Name the distinct approach, key evidence, and safety concerns for each specialized scene type in under two minutes per type

Week 8: Score at least 80 percent on a timed practice assessment and have zero checklist items still marked unknown
