HOSA Forensic Science — Health Science Competitive Event
HOSA Forensic Science is a two-person team competitive event that evaluates the ability to apply forensic and medical science knowledge to simulated investigations. Round 1 is a 50-question MCQ test; Round 2 requires written analysis of an autopsy or crime scene case study.

Frequently Asked Questions
Is HOSA Forensic Science an individual or team event?
HOSA Forensic Science is strictly a team event with exactly two participants per team. Both members collaborate on the Round 2 written case study analysis. Round 1 objective test performance contributes to the overall team score.
What topics should I prioritise for the Round 1 objective test?
Focus heavily on forensic pathology (cause & manner of death, PMI), toxicology (drug metabolism, BAC calculations), DNA/serology analysis, and crime scene investigation procedures. These areas tend to have the highest question density in HOSA Forensic Science tests.
Where can I find official study materials for HOSA Forensic Science?
The official HOSA Competitive Events Guidelines (released annually at hosa.org) list the topic areas and recommended references. Common references include forensic science textbooks by Richard Saferstein ('Criminalistics: An Introduction to Forensic Science') and Henry Lee, as well as HOSA's own practice resources.
