Eligibility
Each International Science and Engineering Fair (ISEF) affiliated fair may send up to two Finalists and one team project to the ISEF. Any student in grades 9-12 or equivalent is eligible, none of whom has reached age 21 on or before May 1 preceding the ISEF.
Requirements
Every High School student must complete (1A) Research Plan and (1B) Approval Form.
Certain projects require additional forms. Experiments that involve human subjects, non-human vertebrate animals, pathogenic agents, controlled substances, recombinant DNA, or human/animal tissue require approval from an Institutional Review Board (IRB) or Scientific Review Committee (SRC) before experimentation begins (see Item #9, Form 1A).
Each student or team must submit a (maximum) 250-word, one-page abstract which summarizes this year's work. The abstract must describe research conducted by the student, not by adult supervisors (see Student Handbook).
Each student should display a project data book and a research paper (see Student Handbook).
All signed forms, certifications, and permits must be available for review at each fair a student enters. We recommend these be kept in a notebook or folder.
Any proposed changes in the research plan by the student after initial IRB/SRC approval must have subsequent IRB/SRC approval before experimentation begins/resumes.
Projects which are continuations of previous year's work and which require IRB/SRC approval must be reapproved prior to experimentation for the current year.
Limitations
Each student may enter only one project.
Team projects may have a maximum of three members (see below).
All exhibits must adhere to ISEF safety and size requirements.
Students may compete in only one ISEF affiliated fair, except when proceeding on to a state fair affiliated with the ISEF from an affiliated regional fair.
