How are DECA competitive events judged?

The chosen answer is correct because DECA competitive events are designed to assess participants on their understanding and application of marketing concepts as well as their overall presentation skills. This focus allows judges to evaluate not just the content of the competitors' work, but also how effectively they communicate their ideas and engage their audience.

While creativity and originality are often valued in various educational contexts and can enhance a presentation, they are not the primary criteria used for judging DECA events. Similarly, team collaboration and communication are important skills, especially in team-based competitions, but they are considered within the larger context of marketing application and presentation effectiveness. Lastly, basing judgments solely on written reports would overlook significant aspects of DECA events, such as oral presentations and interpersonal skills, which are critical components of the competitive experience.
