ISEF/Affiliated Fairs: It is a requirement that affiliated fairs adhere to the International Rules for Precollege Science Research: Guidelines for Science and Engineering Fairs (ISEF Rules) and that students, teachers and parents are informed about these requirements so that they use ISEF forms from the start of research. Students that do not receive the appropriate approvals or complete the necessary ISEF forms in the proper timeline may not qualify for competition at the ISEF.
