Which entity has the authority to authorize DECA's programs?

The correct choice highlights that the United States Congress and the United States Department of Education have the authority to authorize DECA's programs. This underscores the significance of federal oversight and regulation in the realm of educational programs, particularly those that receive federal funding or support. The involvement of Congress and the Department of Education ensures that DECA programs align with national educational standards and policies, promoting consistency and quality in the education system. This federal authorization is crucial for establishing the legitimacy and operational framework necessary for organizations like DECA to function effectively within schools and educational institutions across the country.

The other options, though they may relate to specific educational environments or funding, do not possess the same level of authority as the federal bodies mentioned. Local school boards are limited to their jurisdiction and cannot offer nationwide program authorization. International student organizations may provide support or resources but lack official authority over program approval in the U.S. Lastly, while private educational foundations can offer funding and grants, they do not have the regulatory power to authorize educational programs on a national scale.
