At the Fall Leadership Conference, which of the following is a competitive event?

The Membership Recruitment Poster is categorized as a competitive event within HOSA activities, where participants create and present a visual tool designed to attract new members to their organization. This type of event typically encourages creativity, understanding of effective communication strategies, and an ability to showcase the values and advantages of HOSA membership. The competitive nature is emphasized through judging criteria that may include clarity of the message, design quality, and effectiveness in conveying the organization's goals.

In contrast, the other options listed are more focused on educational or organizational activities rather than competition. A Public Speaking Workshop is an opportunity for members to enhance their communication skills without the competitive element. Similarly, a Fundraising Strategy Session is geared toward learning and sharing ideas about raising funds rather than competing against peers. Lastly, a Health Career Field Trip serves as a practical experience to explore health careers and is not structured as a competitive event.
