What is a characteristic of HOSA's competitive events?

HOSA's competitive events are designed to challenge students' knowledge and practical skills in healthcare and related fields. This focus encourages participants to apply what they have learned in a practical context, fostering both theoretical understanding and hands-on capabilities. By engaging in various competitions, students not only demonstrate their knowledge but also develop critical thinking, teamwork, and problem-solving skills that are essential in healthcare settings. This comprehensive approach ensures that participants are well-prepared for future careers in health professions.

The other choices do not accurately encompass the scope of HOSA's events; they include a variety of formats beyond just written exams, cover a wide array of healthcare topics—not limited to public health—and involve regional competitions leading up to the annual events, enhancing the learning experience through progressive challenges.
