Which category is NOT a membership category in HOSA?

The correct choice indicates that "Postgraduate" is not a recognized membership category within HOSA (Health Occupation Students of America). HOSA encompasses several categories intended to involve various members in the organization, including those in high school (Secondary), professionals who provide guidance and mentorship (Professional advisor), and individuals who have made significant contributions to HOSA or the health profession (Honorary).

The absence of a category specifically named "Postgraduate" reflects HOSA's focus on students currently engaged in educational programs related to health occupations rather than those who have completed their formal education and are not actively participating in HOSA activities. This structure supports HOSA's mission to foster the development of future health professionals, emphasizing active involvement among students and advisors rather than creating a category for those who have transitioned out of the educational system.
