## About this program

Idaho Science & Engineering Fairs let Idaho high-school students present original research at three regional competitions: Northern, Western and Eastern Idaho. Projects follow the applicable ISEF rules and approvals, and expert judges evaluate the work. Selected regional winners can advance to ISEF, with travel support advertised by the organiser.

The page lists the Eastern Idaho fair for February 19, 2027, while Northern and Western dates are pending. It also lists a final project deadline of November 5, 2026 at ‘11:59 MT’ without specifying a.m. or p.m. Confirm the deadline for your region, required approvals, costs and entry instructions before beginning or submitting a project.

Fields above come directly from the catalog listing. A field with no stored value is omitted.
