ISEF Fairs

Intel ISEF LogoThe Intel International Science and Engineering Fair (ISEF) is the largest pre-college science fair in the world. Annually, over 7 million people compete to qualify for this fair, and only 1500 students are selected to attend (~0.2% of participants). To qualify for this prestigious fair, you must compete at the Regional Competition (MSRC) and the State Competition (DVSF):


  • The regional competition, Montgomery County Science Research Competition (MCSRC) is typically held in late March
  • It requires the use of a tri-fold, display board, log book and research report
  • The projects are divided by grade, and then again by category. Students are competing against the other students in their category.
  • On the actual competition day, the category judges usually come by the projects in pairs of two. Students are expected to give a brief explanation of their projects and then answer any questions the judges have. Students are required to stay by their projects until their category judging has been completed.
  • The first, second, and third place winners from each category are sent on to the Delaware Valley Science Fairs

  • The state competition, Delaware Valley Science Fair (DVSF), is modeled similarly to the MCSRC fair, but on a much larger scale
  • It takes place at the Oaks Convention Center
  • The first, second, and third place winners of the 9th, 10th, 11th, and 12th grade fairs qualify to compete at the Intel International Science and Engineering Fair. These winners are selected from the 13 first place category winners from each grade (9-12).
  •  Additionally, there are category awards, wining cash prizes, special awards, the potential for scholarships.

  • The Intel International Science and Engineering Fair competition this year is taking place in Los Angeles, California.
  • Approximately 1,700 high school students from over 75 countries, regions, and territories are awarded the opportunity to showcase their independent research and compete for approximately $4 million in prizes.
  • Plane tickets, accommodations, and entrance fees are all covered by the DVSF and its many generous donors.
  • This week long competition consists of numerous mixers, planned events, up-scale dinners, and more. Attendees meet the best and brightest from around the world, and are encouraged to make as many friends as possible.

The display for the ISEF fairs is a trip-fold display board. The maximum size of this board is 48 inches wide, 30 inches  deep, and 108 inches high. The project must be self-supporting and fit inside the allotted space. Names of schools must not be seen on the front display or in any written material. Number the subjects in your data to keep them anonymous.. Pictures of subjects are allowed with their approval. Indicate credit for pictures displayed. When the exhibitor receives the project number at registration put it on everything. Eliminate school names on log books, abstracts.
