What document symbolizes the governance and operations of DECA?

The national constitution serves as the foundational document for DECA, outlining the organization's structure, governance, and operational procedures. It provides essential guidelines on how DECA functions at various levels, including local, state, and national. The constitution establishes the framework for decision-making, responsibilities of officers, and the overall mission and vision of DECA.

In contrast, the other options represent important aspects of DECA but do not hold the same authoritative status. The membership application pertains specifically to the process of joining DECA rather than its governance. The code of conduct outlines expected behaviors and ethical standards for members but does not define the overall structure of the organization. An annual report provides a summary of activities and accomplishments over a year, serving more as a reflective document than a governing authority. Therefore, the national constitution is the key document that symbolizes and governs the operations of DECA.
