Regeneron ISEF 2023 is being planned as a fully in-person event. Given the challenges many affiliated fairs have faced during the pandemic, Society for Science has determined that we will not raise fees for 2023. However, we want to notify fairs now that we will raise fees for Regeneron ISEF 2024 to manage the costs of inflation and the growing cost of running the event. We anticipate the fees will increase by 5%-10% for Regeneron ISEF 2024.

Affiliated fairs pay two kinds of fees to participate at Regeneron ISEF. The first set of fees are Affiliation Fees, and these must be paid for the fair to affiliate with the Society. Affiliation fees are non-refundable as they support the Society’s annual management of the fair network. A detailed breakdown of affiliated fees can be found below.

The second set of fees are Registration fees that must be paid for Finalists and Official Party Members to attend Regeneron ISEF. This is a separate fee from the affiliation fee and is paid in the Spring. Affiliated Fairs are responsible for paying all expenses for all finalists and one adult in charge representing the fair at ISEF. A detailed breakdown of registration fees can be found below.

Affiliation Fees

Fairs pay a fee to affiliate with the Society for participation in the Regeneron ISEF and our Middle School research competition (Broadcom MASTERS through 2022). For our Middle School research competition, the fee is $75 if the fair is not ISEF affiliated.

Affiliation fees are based on the relative size of a fair based on a range of project allocations. This is not determined by how many projects a fair has committed to sending to Regeneron ISEF, but the allocation computed historically. Please contact Society staff at ISEF@societyforscience.org to understand your allocation and to request a review. For Regeneron ISEF, the fee for a fair of an allocation of 1-3 projects will be $750. There are incremental rates for those with 4-9; 10-15; or over 15 projects allocated. Please review the full chart of fees below for specific amounts.

A $50 discount is given to fairs that affiliate by the October 16 deadline. A $75 late charge will apply to fairs that submit their affiliation fee after the December 31 payment deadline.

Affiliation Fees
Base Fee, fairs with 1 to 3 projects	$750
Base Fee, fairs with 4 to 9 projects	$1250
Base Fee, fairs with 10 to 15 projects	$2250

Registration Fees

Registration fees must be paid for every member of an affiliated fair’s Official Party. Fees must be paid by the payment deadline. If fees are not paid by the deadline, they must be paid onsite at Regeneron ISEF and an additional $25 will be charged per registrant.

Additionally, there are limits to the number of Other Official Party Members a fair can bring. This limit is based on the number of projects a fair is allocated. Fairs are permitted to bring Official Party over the limit, however, a higher fee will be charged for those OFP members. The limits are as follows:

• Fairs with 1, 2 or 3 projects may bring individual or team Finalists representing the projects committed and a maximum of 6 remaining official party.  (A fair must minimally have 1 Adult-in-Charge to chaperone the Finalists.)
• Fairs with 4, 5, or 6 projects may bring individual or team Finalists representing the projects committed and a maximum of 10 remaining official party.  (A fair must minimally have 1 Adult-in-Charge to chaperone the Finalists.)
• Fairs with 7, 8, or 9 projects may bring individual or team Finalists representing the projects committed and a maximum of 15 remaining official party.  (A fair must minimally have 2 Adults-in-Charge.)
• Fairs with 10 projects or more may bring individual or team Finalists representing the projects committed and a maximum of 20 remaining official party.  (A fair must minimally have 2 Adults-in-Charge.)

Registration Fees

Adult-in-Charge	$350
Other Official Party	$350
