IAI CCSI study guide
IAI CCSI · Work through your exam, one topic at a time.
The Certified Crime Scene Investigator (CCSI) credential is offered by the International Association for Identification (IAI), which describes itself as the oldest and largest forensic association in the world. The IAI states that it represents a diverse, knowledgeable and experienced membership assembled to educate, share, critique and publish methods, techniques and research in the physical forensic science disciplines, and it lists Crime Scene Investigation among its forensic science disciplines. The CCSI is therefore aimed at practitioners who process and document crime scenes and want a professional certification in that discipline; it sits alongside the IAI's other certification offerings, which the site groups under Bloodstain Pattern, Crime Scene, Footwear, Forensic Art, Forensic Photography & Imaging, Forensic Video, Latent Print, and Tenprint Fingerprint, each with its own certification board. Candidates should treat the exam as a test of applied scene practice: scene security and documentation, photography and imaging, evidence recognition, collection and packaging, chain of custody, and the reasoning behind those steps. Because the IAI publishes overall policies and procedures for certification plus discipline-specific boards, preparation should start with the official certification policies and the Crime Scene board's requirements, then move to systematic review of scene-processing fundamentals and supervised field experience.

01Crime Scene Investigation
Crime Scene Investigation is the IAI CCSI domain that tests whether you can secure, document, search, and process a scene so physical evidence survives courtroom scrutiny. Questions mix field procedure with legal defensibility: contamination control, documentation sequence, packaging choices, chain of custody, and reconstruction reasoning. First-responder priorities: preserve life, secure the scene, detain witnesses, request resources, and start a scene log. Do not process before security is established.

- Practice questionsAt a crime scene, which action best describes the primary purpose of establishing a secured perimeter before evidence documentation begins?

- Key termsChain of custody. The chronological, documented record of who collected, handled, transferred, and stored an item of evidence, from seizure to courtroom.
- Study planMap the full CCSI crime scene investigation domain into a written outline covering scene security, documentation, evidence recognition, collection, packaging, and chain-of-custody topics.
- Common mistakesMost study material focuses on forensic technique and treats legal justification as background; candidates memorize the sequence of photography, sketching, and collection without attaching the warrant, consent, or exigency basis that permits entry and seizure.
