RULES CHANGE: In keeping with ISEF policy, there is no longer a special category for team projects. Team projects now compete in the scientific category of their research.

JUNIOR DIVISION: Grades 5-8

- Behavioral & Social Sciences

- Botany & Zoology

- Chemistry

- Engineering

- Environmental

- Math & Computers

- Medicine & Health

- Physical Science

SENIOR DIVISION: Grades 9-12

ASEF categories are aligned with those used at the Intel International Science and Engineering Fair. Categories have been established with the goal of better aligning judges and student projects for judging at the Intel ISEF.
