Where can competitors find the appointment times for the event?

Competitors can find the appointment times for the event in multiple reliable locations: the HOSA app, the HOSA website, and CE Headquarters. This multifaceted approach ensures accessibility for all competitors. By utilizing a combination of a mobile app and an official website, HOSA caters to different preferences and enhances convenience. The inclusion of CE Headquarters as an information source further supports the notion that competitors have multiple avenues to obtain important event details. This flexibility helps ensure that participants are well-informed and can effectively plan for their events.

The other options limit the sources of information, which may not be practical for all competitors. For example, relying solely on the HOSA website or email communications could hinder access for those who may not have immediate access to these platforms. Additionally, local HOSA chapters may not consistently have updated or comprehensive information on appointment times, making them less reliable as a singular source. Thus, option A stands out as the most comprehensive and effective choice.
