IAI CP2 study guide
IAI CP2 · Work through your exam, one topic at a time.
CP2 refers to the bloodstain pattern certification offered within the International Association for Identification (IAI) certification program. The IAI describes itself as "the oldest and largest forensic association in the world," and its site lists Bloodstain Pattern among the certification disciplines alongside Crime Scene, Footwear, Forensic Art, Forensic Photography & Imaging, Forensic Video, Latent Print, and Tenprint Fingerprint. The association also maintains a Bloodstain Pattern Identification Subcommittee within its Science and Practice Committee structure, and publishes Overall Policies and Procedures governing certification. This credential is aimed at analysts and investigators who examine bloodstain evidence and want independent verification of their knowledge; it is not a training course, and it is separate from any university degree or agency title. Because the public source page does not publish the exam blueprint, item count, time limit, passing score, fee, retake rules, or validity period, this page does not state them. Candidates should confirm every administrative detail directly with the IAI certification program before applying, since policies are revised. Topics on this exam: Bloodstain Pattern Analysis. The IAI CP2 study guide has 1 section and about 384 words.
01Bloodstain Pattern Analysis
This domain tests whether you can classify bloodstains by the physical mechanism that produced them, extract directionality and angle from individual stains, and reconstruct a three-dimensional area of origin without overstating certainty. Questions are terminology- and geometry-heavy, and they reward examiners who separate what a pattern proves from what it merely suggests. Before naming a pattern, state three things: the mechanism (gravity, momentum transfer, expiration, arterial pressure), the direction of travel, and any post-deposition alteration. Passive patterns include drip, flow, pool, and saturation.

- Practice questionsIn bloodstain pattern analysis, a stain deposited when a blood drop falls vertically onto a horizontal surface is best described as which type of stain?
- FlashcardsImpact spatter. Blood dispersed by force; stain sizes vary with the energy of impact, typically 1–4 mm for medium-velocity events such as blunt force or stabbing.
- Cheat sheetImpact spatter: stains are generally 1–4 mm; fine spatter under 1 mm indicates high-velocity impact (gunshot, machinery, explosion); medium velocity 1–4 mm (blunt force, stabbing); low velocity greater than 4 mm (dripping, bleeding under gravity).
- Key termsbloodstain pattern analysis (BPA). The reconstruction discipline that examines the size, shape, distribution, and orientation of blood deposits to infer the physical events that produced them, such as impact, projection, or contact.
- Study planDefine the three physical mechanisms of bloodstain formation (passive, projected, transfer) and classify 20 described stains into them without error.
- Common mistakesCandidates study stain photographs and memorise labels such as 'high-velocity impact spatter' or 'cast-off' as if the exam were a naming quiz.
