 Challenge Synopsis

The World Finals consists of 5 to 10 DECA-Challenges, 5 Team Challenges, and 1 DIY-Challenge, Goldberg Machine Challenge, AI Coding Challenge. National (chapter-level) Competitions may be composed of the same programs. 


This challenge is an event that anyone can participate in without practice or preparation in advance. Therefore, challenges are presented on the day of the competition and necessary materials are provided by the organizers. The advantage of this challenge is to enable individuals to demonstrate their potential abilities. Therefore, students from all over the world can participate without any burden. It becomes a "team with students who don't know each other" to solve the task, and in the process, it receives team evaluation and individual evaluation.

In conclusion, this competition is a competition that values experience and process, and students who participated for the first time are also very satisfied and fulfilled, so they continue to participate every year. In addition, it is highly evaluated as a program that students, parents, and guidance teachers are all satisfied with. Surprisingly, the first participants won many awards!

The competition consists of five tasks, three team tasks (one team consisting of no more than 4 members) and two  individual tasks. The time limit given to solve each task ranges from 90 to 100 minutes.

The purpose of these tasks is to have students who do not know each other work creatively as teams, so that their creativity can be accurately evaluated. Team members must cooperate together to solve the given tasks. (Participants are randomly grouped into teams for each division by the organizers; therefore, members of an organization who apply for DECA-CHALLENGE together will not necessarily be put onto the same teams.) Scoring will be by a ranking based on the addition of individual and team scores.

Participants have to meet, communicate, and collaborate with a countless number of people in their lives. Therefore, these tasks offer them a very meaningful and valuable experience.

DECA-CHALLENGE's individual tasks, which must be solved by the participants solely, are designed to assess their individual creativity and problem-solving skills. 

All tasks are confidential and will be announced on the day of the competition in line with the spirit of DECA-CHALLENGE.

Team Challenge

DIY challenges are challenges that teams (consisting of 4-8 people) develop on their own and for which they create a scenario, present a performance, and are evaluated by a panel of judges.

When it comes to enhancing creativity, questions are more important than answers, so this year teams will compete by coming up with creative solutions to their own challenges. It may be difficult for teams to develop their own challenges, and hence we will accept those that are based on the challenges or long-term programs from other competitions. However, in the event teams do decide to refer to other challenges, they must cite their sources.

Team Challenge

Teams of 4-8 people will pick among the 5 team challenges.  Each team must create a storyline, write a story,  assign roles, make costumes and setting, and perform a theatrical play. Through these challenges, creativity, problem-solving skills, teamwork and time management skills will be cultivated. The subject matters covered by our Team Challenges are as follows.

CREDECA Goldberg Machine Challenge

This challenge is part of the demonstration event of the 2019 CREDECA World Finals. Starting in 2019, we will hold a separate CREDECA Machine World Contest. At the CREDECA World Finals, 4-6 people can participate as one team. 

This challenge was created by Rube Goldberg, who was frustrated at the fast pace of modern society. Instead of doing a complicated task quickly and easily, he instead wanted to create a simple task to be performed as slowly and complicated as possible. The mentality of this challenge is not to focus on the results, but rather to enjoy the process of completing the event while testing creativity. Recently, these machine creating events are being used in movies, commercials and games. Now, we challenge you all to participate as well.


The final mission of 2019 is "Hole in One " and must follow the following criteria:

  • 1st class (Elementary) - 9 steps

  • 2nd class (Middle School) - 12 steps

  • 3rd class (High School) - 15 steps

CREDECA AI Coding Challenge

This challenge is to create and demonstrate an actual device by performing AI coding according to the presented problem.


Our WAC presents the "CREEDECA Competition Program to Demonstrate and Learn" as a method of international standard AI coding education. Our researchers have been studying AI coding education for the past 10 years.

Our AI coding education is that "the students should abandon the idea of teaching, realize on their own, and develop their ability to discover and solve problems through collaboration."

Researchers agree that this is the spirit of CREDECA, students directly realize the meaning of challenge and achievement, and that the educational effect (computing thinking ability and coding ability) was very large.

Before participating in the competition, 2-4 people form a team to solve the challenge, and the device manufactured on the day of the competition is operated with AI coding to be evaluated by the judges
