Welcome Teachers !

You will use this website to keep track of your students' paperwork. 

When your students fill out their registration, their responses to questions will determine which forms they will need to submit.  However, if you would like to look at this before your students register, click the link below for the ISEF Rule Wizard which allows you to answer a few questions, and shows you which forms your students will need to submit. 

ISEF Rules Wizard

***Please make sure all of your students have registered for the correct fair (Northern, Eastern, or Western Idaho) and category***

Virtual Presentation Information

We will be following the International Science & Engineering Fair (ISEF) guidelines for student virtual project presentations this year in order to best prepare our participants to be ISEF Finalists.  The ISEF sponsors have indicated that they will be coordinating live virtual interviews as well as the presentation documents described below, but have not yet released details of that.  The three presentation pieces (excluding the interview) include an abstract (similar to previous years), a PDF Project Presentation doc summarizing the student research (max of 12 pages), and a Quad Chart. These last two are detailed here: Project Guidelines.pdf


STEM Action Center ISEF Materials Grant

Public school educators with students participating in a regional Idaho Science and Engineering Fair can apply for up to $1,000 to purchase classroom materials for student projects. The amount awarded will be based on the number of student projects approved to participate in the fair. Educators will receive $100/student project, up to a maximum of $1,000. 

Learn more and apply at https://stem.idaho.gov/apply/isef-support/

If you have any questions or concerns please contact us at: idahosciencefairs@gmail.com

Teacher Registration

Please RegisterT.pptx through this site before having your students register.  This allows your students to choose you from a pulldown list - rather than having 5 different versions of your name entered by various students.  

If there are any problems with registering, please contact Merrie Rampy at idahosciencefairs@gmail.com and we will resolve the issue ASAP.

Judging is an extremely important part of the fair, and is one of the most valuable experience for our students. We definitely appreciate your willingness to participate in this process.  All information will be kept confidential and will be used only for the purposes of operating the Idaho Science & Engineering Fairs. 

Previous experience in judging science fairs at the local, state, or national level is helpful, but not required. Please review the requirements below before registering. The requirements may be found at: Fair (at the top of the page) --> Fair Information --> Judging Criteria.

If you have any questions or concerns please contact us at: idahosciencefairs@gmail.com

There will tentatively be six judging categories for all three regional fairs:

     1. Animal, Biomedical, and Microbiology

     2. Behavioral and Social Sciences

     3. Earth, Environmental, and Plants

     4. Engineering

     5. Math, Computer Science, and Embedded Systems

     6. Physical Sciences (Physics, Astronomy, Chemistry, Materials,...)

Descriptions of each category may be found by going to Fair (at the top of the page) --> Fair Information --> Categories.

To start the registration process, click on Register (at the top of the page) --> Judges.
