Idaho Science & Engineering Fairs

Due to an insufficient number of qualifying projects, the 2024 Idaho Science & Engineering Fair (IDSEF) has been cancelled. We are currently working to restructure and improve this program for the future. IDSEF will return for the 2024-2025 school year.

Idaho Science & Engineering Fairs
About the Fair

Each spring, the Idaho STEM Action Center and its partners proudly host the Idaho Science & Engineering Fair (IDSEF) for Idaho students in grades 9-12. Participating students engage in original STEM research projects throughout the school year that allow them to explore their interests and learn/implement the same techniques used by scholars in their field. The IDSEF event provides the opportunity for these students to present their findings to the public and a panel of expert judges. A variety of honors and scholarships are awarded each year to recognize students with exceptional research projects.


Students with the top projects from around Idaho have had the opportunity to attend/compete at the Regeneron International Science & Engineering Fair. The STEM Action Center and its partners pay all expenses for participants who qualify for the international competition. (Learn more about the Regeneron International Science & Engineering Fair at

Since 2017, the Idaho Science & Engineering Fair (IDSEF) has consisted of 3 separate regional competitions: the Northern Idaho Science & Engineering Fair (NISEF), the Western Idaho Science & Engineering Fair (WISEF), and the Eastern Idaho Science & Engineering Fair (EISEF). However, transitions in the program’s structure and staffing have necessitated a change for this year. More information coming soon. 

Participant Travel to the Competition

We recognize the importance of increasing accessibility for participants across Idaho and are exploring options to return IDSEF to 3 regional competitions in the future. To support participants in attending this year’s state-wide competition, the STEM AC will cover travel costs and lodging for students and their sponsoring educator in accordance with State of Idaho and STEM AC travel policies. Please contact for more information. (NOTE: If a team reserves a blocked room for the competition and does not attend, they may be required to reimburse the STEM AC for any costs incurred)

Educators supporting student projects competing in their regional Idaho Science & Engineering Fair may apply for grant funding. Just click the IDSEF Support Sponsorship button above!
