Elementary Science Olympiad (ESO) is open to all public, private, charter, and home schools in Hawaii as well as groups that involve students in grades 3 – 6 (i.e Cub/Girl/Boy Scouts and after school programs).  Since some Hawaii Elementary schools only go to 5th grade while others include 6th grade, we allow up to seven (7) 6th grade students on a team as long as those students were not also on a Division B team.

Schools MUST register to be eligible to compete in any of the events! There will be no registration fee for teams this year. Each school/organization will be allowed to register up to two teams.

If you would still to inquire about participating or other inquiries regarding tournament details and logistics (including event offerings, schedule, etc), please contact the tournament director at
