Which of the following contributes to DECA's focus on leadership?

The focus on leadership within DECA is strongly supported by the requirement for members to lead a chapter project. This responsibility not only encourages individuals to take initiative but also helps develop vital leadership skills such as organization, communication, and teamwork. Leading a project allows DECA members to apply their learning in real-world scenarios, fostering a deeper understanding of both leadership roles and the business concepts they study.

In contrast, while networking opportunities with peers can enhance leadership development through collaboration and exchange of ideas, they do not directly involve the actionable aspects of leadership that a chapter project entails. Improvements in public speaking can certainly be an important skill for a leader, but they are only one part of the broader leadership development DECA offers through hands-on project experience. Participation in national testing can serve as a measure of knowledge and competence, but it lacks the interactive and practical components that leadership projects provide. Thus, leading a chapter project is the most direct and impactful way DECA cultivates leadership skills among its members.
