Who approved the endorsement of HOSA?

The correct choice is Ernest L. Boyer, who played a pivotal role in the endorsement of HOSA (Health Occupations Students of America). His influence as an educator and advocate for health professions was significant during the establishment of HOSA in the early 1970s. Boyer's support helped legitimize HOSA as a national organization aimed at promoting career opportunities in health care and enhancing the quality of education for health profession students.

This endorsement was crucial because it provided a foundation for HOSA's growth and development, securing partnerships with various educational institutions and health organizations. Boyer's commitment to advancing education in health professions through HOSA mirrored the organization's goals of encouraging leadership development and career readiness among students in the health care field.

The other individuals listed did not have the same level of involvement in the approval or endorsement process for HOSA, which is why they do not hold the correct answer in this context.
