Which group is not included in the eligible divisions for the event?

The group that is not included in the eligible divisions for the HOSA Public Service Announcement event is the Middle School division. The HOSA organization typically categorizes its members into divisions based on their level of education. The collegiate division is for college students, the secondary division is for high school students, and the postsecondary division is typically for those in vocational or technical training programs after high school.

Middle School is generally not included in these specific competitive categories because HOSA primarily focuses on encouraging and promoting health professions among high school and college students. As a result, the focus is directed towards students who are at a stage in their education where they can actively engage with the healthcare industry through projects and competitions that are more aligned with their current knowledge and experience levels.
