In which decade did the DECA diamond evolve?

The DECA diamond evolved in the 1990s as part of the organization's effort to modernize and enhance its branding. This evolution reflected changes in marketing education and aimed to visually encapsulate DECA’s mission and the skills that members develop. During the 1990s, DECA sought to solidify its identity and increase its appeal to a broader audience, and the diamond symbol became a key element in representing the organization’s focus on developing leadership and professional skills among students. The introduction of this new symbol helped to unify the DECA brand and communicate its commitment to preparing future leaders and entrepreneurs in marketing, finance, hospitality, and management.
