Regeneron ISEF: 2026 Results and 2027 Los Angeles Dates
The completed Regeneron ISEF 2026 cycle, confirmed 2027 dates in Los Angeles, current international rules, and Singapore's affiliated-fair route.
Q: When and where is Regeneron ISEF 2027? A: Society for Science lists Regeneron ISEF 2027 in Los Angeles, California, from 8 to 14 May 2027. ISEF 2026 in Phoenix has concluded, and the 2027 international rules are already available.
Current status
Regeneron ISEF 2026 took place in Phoenix, Arizona, from 9 to 15 May. Society for Science reports more than 1,700 finalists from over 365 affiliated fairs and more than 60 countries and territories, competing for over US$7 million in awards and scholarships.
That cycle is complete. Students preparing now should use the 2027 rules, not a 2026 form pack, and should follow the current timetable of their own affiliated fair.
How students qualify
Students do not normally register directly for ISEF. They qualify through a Society-affiliated fair, which has an allocated number of projects that it may send.
Science Centre Singapore identifies the Singapore Science and Engineering Fair (SSEF) as the local affiliated route, with selected winners representing Singapore. The current SSEF notice controls local eligibility, submission dates, forms, and selection.

Do not treat the international May dates as the SSEF project deadline. Local research approval, fair submission, and judging happen earlier.
Compliance comes before results
The current international rules cover eligibility, team projects, forms, and research involving people, vertebrate animals, biological agents, hazardous materials, and other regulated work. Some projects need approval before experimentation starts.
