Contest Rules

These are the contest rules one agrees to when participating in Caribou Contests:

We count on the supervising adults and the integrity of participants to ensure that these rules are followed. However, we have also developed a series of statistical tools to help identify unfair participation. When unfair participation is detected, we reserve the right to remove the student’s contest entry from ranking. For more information about these tools, see our page about Unfair Participation.
