We’ve added two rules for the 2025 fair. Students and teachers should makes sure they are familiar with all fair rules, as listed on the Rules Page.

NEW RULE: Honesty is expected during every phase of the project.  Your science project must be your own work. In particular, artificial intelligence (AI) may NOT be used to design your experiment, write any part of your project, or create your display.  Your project must not include fraudulent data, plagiarism, or inappropriate use of AI.

NEW RULE: After competing at your Regional Fair, projects may not be changed for WSSEF or ISEF. You may collect additional data using the SAME methodology that was approved by your regional fair and/or update your project display with additional data analysis.
