Welcome to the Regeneron Westchester Science & Engineering Fair (WESEF)

The Regeneron Westchester Science & Engineering Fair (WESEF) encourages students to participate in hands on science by providing a forum for showcasing the outstanding research of high school students in Westchester & Putnam counties of New York State and sponsoring the top students from the fair to advance to the REGENERON International Science & Engineering Fair.

Save the Date! WESEF 2025 will be March 15th, 2025!

Planning is well underway for the 2025 Regeneron Westchester Science & Engineering Fair! 

Over 800 high school students from Westchester and Putnam Counties have registered to participate this year! Forms have been submitted and paperwork reviewed. 

At this time, we still need additional judges to sign up!  Please see the Judge Flyer and use this link to sign up for the event on Saturday March 15th, 2025 which will take place at Somers Middle School and Somers High School.

The top 20 projects at the 2025 Regeneron WESEF will represent our region at the Regeneron International Science & Engineering Fair which will be held in Columbus, Ohio in May 2025.
