Affiliation Fees

Fairs pay a fee to affiliate with the Society for participation in the Regeneron ISEF and Broadcom MASTERS. For Broadcom MASTERS, the fee is $75 if the fair is not ISEF affiliated.

It has been determined that the Regeneron ISEF will be held as a hybrid event in 2022. 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. Fairs do not have to send their allotted number of projects to the Regeneron ISEF and may instead commit to sending fewer as their budgets allow.

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

Affiliation fees are non-refundable as they support the Society’s annual management of the fair network.
