Which of the following is true about DECA's membership demographics?

The statement that membership includes high school and collegiate members is accurate because DECA is organized to serve both student levels, allowing high school students to participate and develop their skills while also offering collegiate-level programs for those in post-secondary education. This dual membership enables a broad range of experiences and networking opportunities for students at various stages of their education in the fields of business and marketing.

High school members engage in competitions and educational events tailored to their level, while collegiate members can take part in more advanced activities that prepare them for their careers after graduation. DECA’s inclusive structure supports students' growth and development, which is why the correct option reflects this comprehensive approach to membership.

The other options do not accurately represent DECA’s membership structure. For instance, restricting membership solely to high school students would exclude a significant portion of participants, and saying there are no alumni members overlooks the valuable role of former members in promoting and mentoring current students. Furthermore, limiting membership only to educators would entirely dismiss the student-centric mission of DECA, which is aimed at engaging and developing young individuals in business and leadership.
