OFFICIAL RULES - US TEAMS

The OurEcho Challenge is offered only within the 50 United States and the District of Columbia. Middle school-aged students (attend school in Grade 5 through Grade 9 during the Entry Period or be Grade 5 through Grade 9 equivalent age as determined by Administrator in their sole discretion for students who are not in a traditionally-graded educational environment) are encouraged to work in teams of 1-3.

Given the age of students, an adult (21+) MUST submit each entry online on behalf of the teams they are mentoring. Mentors can be traditional educators, parents, and/or adult facilitators of more informal learning environments.

All students will require a permission form signed by their legal guardian to be uploaded with their entry.

Any former member of an OurEcho Challenge Finalist Team must not re-use their prior OurEcho Challenge finalist entry materials to enter the OurEcho Challenge.
