Welcome to the York - Adams Science and Engineering Fair.  This fair is a part of the International Science and Engineering Fair (ISEF).  We serve all schools and students from York and Adams counties.  The York County Science and Engineering Fair was planned by a committee of local volunteers representing technical and educational organizations for the purpose of providing York County students with an opportunity to expand and increase their expertise in science and engineering.  It also provides additional incentive by offering awards, scholarships and an occasion to receive expert evaluation of projects for future science fair participation.

Here is a copy of the 2026 YASEF Program

If you have questions about your project, please consult your science teacher.  Question about the fair can be sent to Jamie McFadden or Roni Reed, Co-Fair Directors.
