No Tricks, Just Cool Science! 🎃
Honors Division Approval Deadlines
All paperwork must be submitted through MySciFair to be reviewed by the Safety Committees. Please check the Honors Division Rules and Regulations to see if your project will require prior approval. Projects submitted to the Fair that did not receive prior approval, and SHOULD HAVE, will not be eligible for competition or awards.
Registration for the 2027 STL Science Fair will be on the MySciFair platform. No paper forms will be permitted for in-person fair, all forms will be signed online! Another huge bonus of this platform: once you have an account set-up you use the same one every year!

Regional Division Registration
Open Until 02/28/27
Starting in 2027, all divisions of the STL Science Fair will have only two rubric options. Projects must declare whether they are a Science project or a Maker project and will be judged using the corresponding rubric. All rubrics are posted on the STL Science Fair website.

Please note that raw scores are not distributed to participants after the Fair. Comments may be distributed if they are helpful to the student.
