NEWS UPDATE: March 23, 2020 -- The Regeneron International Science and Engineering Fair made the difficult decision to cancel the 2020 ISEF due to the COVID-19 outbreak.   Although our students will not be able to compete on the world stage where GSDSEF students always do extremely well, we congratulate these students for their extraordinary work and research, as well as ALL students who participated in the 2020 GSDSEF.

2020 GSDSEF Highlights

In the 66th Annual Greater San Diego Science & Engineering Fair, we had

  • over 880 students who submitted projects to be screened into the GSDSEF and over 700 were recommended to participate in the Fair
  • 574 total students who applied and were accepted into the 2020 GSDSEF
  • 3 options to be judged (available this year only) -  1) be judged in person, 2) set up their display boards and send in a video for judging, 3)  be judged only by their display board and notebook
  • 250 – 300 judges who decided the Categorical Place Awards in 16 categories of projects with displays present, by interviewing students in person, and/or reading notebooks and display boards, and, if submitted, viewing videos
  • 16 6th graders judged for the first time in the GSDSEF
  • 336 Individual Projects and 53 Team Projects were judged in Junior Division
  • 106 Individual Projects  and 6 Team Projects were judged in Senior Division
  • 79 Professional Societies and ISEF Affiliates who gave awards and scholarships
  • 245 Professional Society Awards and Special Awards given to participants totaling over $24,000
  • 89 students nominated for the California Science and Engineering Fair
  • 55 students nominated for Broadcom MASTERS
  • AND... an ELEMENTARY SHOWCASE with students who had won top awards in their school (see below!)


Each Professional Society handles their awards differently. In most cases, the Professional Society contacts the winners of their awards directly within a few weeks of the Fair.

Unfortunately, the 2020 California Science and Engineering Fair has been canceled due to COVID19 concerns. However, we congratulate these students for being nominated to participate in the CSEF.
