Event Overview

Health Science is a Division C event that is dedicated to the study of the human body, including human anatomy, normal and abnormal bodily function, health and health maintenance, and the illness and disease of organs and organ systems. The systems studied are rotated from year to year and may include different disease scopes or focuses, depending on the specified systems.

Competition Format: Event exams may either be in the written test or station format, although the station format is preferred at the National level. Participants are given 50 minutes to complete an exam covering all of the event topics listed in the official rulebook. Teams are ranked by a raw score, determined by the number of correct answers, with ties broken based on either preselected 'tiebreaker' questions and/or quality of free-response answers.
