DECA is one of the oldest and largest high school business organizations in the United States, built around five career areas - marketing, finance, hospitality and tourism, business management and administration, and entrepreneurship - with its Competitive Events program at the center.
A student joins a chartered school chapter as a dues-paid member and then picks an event: an individual role-play, where competitors receive a business scenario and a set of performance indicators, prepare for about ten minutes, and present to a judge acting as an executive; a two-person Team Decision Making case; or a prepared written project such as a business plan, an integrated marketing campaign or an operations research report.
California’s ladder is clear. Students compete at one of three District CDCs in January 2027, top finishers advance to the State CDC in Anaheim at the end of February, and top-ten state finishers claim ICDC places. ICDC, the culmination of the year, runs April 17-20, 2027 at the Anaheim Convention Center.
The real barrier is not difficulty but deadlines: affiliation, membership entry, registration and payment all have hard cutoffs months ahead.
