2025 Fair Registration is Now Open

The 2025 Mercer Science and Engineering Fair (MSEF) will be held in-person in March 2025. The time and location are still pending but this information will be posted here soon. You can start an application now. 

We have a new website for the 2025 Mercer Science and Engineering Fair. It works a lot like the old one and the application process is almost identical so those that used it last year will be familiar with it. The two main things that have changed is the presentation and the documentation. The latter is still a work in progress. 

New user accounts can now be created. 2025 MSEF submissions can be created once a new account has been set up. 

Judges that had an account on the old site can request a new password. Contact us if you have issues. You can use your email address to sign in or to get a new password. All teachers will need to sign up for a new account. Teacher and student accounts WERE NOT MIGRATED from the old website. 

All fair submissions must provide ISEF forms. Use the ISEF Rules Wizard to determine what forms are needed. ISEF forms MUSE BE filled out BEFORE research or experimentation starts and uploaded as part of the submission process. Some forms must be completed after a project is completed.
