There are three Science Olympiad Divisions:
- Division A (Grades K-6)
- Division B (Grades 6-9)
- Division C (Grades 9-12)
Students on the team must be from the membership school; and a school is considered to be a separate school if it has a separate administrator. Recruiting from neighboring schools, districts, counties or states is not permitted. If you are home-educated or attend a virtual school, please see team qualification requirements under the national Home and Virtual School Policy. Any student can compete at only one Division level (either Division B or C, not both) at a single school. If you feel that your school is a small school, please consult the national Small School Policy.
Division C Team Membership Rules
A team may have up to fifteen (15) members. A maximum of seven (7) 12th grade students is permitted on a Division C team.
Division B Team Membership Rules
A team may have up to fifteen (15) members. A maximum of five (5) 9th grade students is permitted on a Division B team. Because middle schools that do not have grades 7, 8, or 9 are at a slight disadvantage, they may invite any combination of up to five (5) of their last year's 6th, 7th or 8th grade students to be part of the team.
- A school with grades X-9 can only have 5 students from grade 9 (in their current enrollment)
- A school with grades X-8 can only bring back 5 students from grade 9 (from the previous year's enrollment of 8th grade students)
- A school with grades X-7 can only bring back 5 students from grade 8 or 9 (who had been previously enrolled in that school as a 7th grade student)
- A school with grades X-6 can only bring back 5 students from grades 7, 8 or 9 (who had been previously enrolled in that school as a 6th grader)
