Each year, Vietnam DECA organizes its official competitive programming into structured annual seasons. Every annual competitive season includes two triannual city-level competitions (held in both Hanoi and Ho Chi Minh City), the final Vietnam DECA Nationals Conference, and other chapter-on-chapter friendlies. In fostering sustained interscholastic collaboration and competition among chapters and schools across the country, Vietnam DECA aims to create meaningful opportunities for its chapters and student members to translate theoretical classroom knowledge into practical, real-world application.
