Affiliation Fees

Fairs pay a fee to affiliate with the ISEF and Broadcom MASTERS. For Broadcom MASTERS, the fee is $75 if the fair is not ISEF affiliated. For ISEF, the base fee is $1250 for fairs that are allotted one to two projects. Fairs with more than two projects will pay an additional $250 per project. Fairs do not have to send their allotted number of projects to the ISEF and may instead commit to sending fewer. This helps save on the registration fee and travel costs for the finalists and may help reduce the affiliation fee as well.

A $50 discount is given to fairs that affiliate by the deadline in early October. Fairs are often dependent on universities or school systems to pay their affiliation fee, and those systems’ budget calendars vary widely, so fairs are given until mid-February to pay their affiliation fee. A $75 late charge will apply to fairs that submit their affiliation fee after the payment deadline date.

Affiliation fees cannot be refunded nor can the number of projects be increased after affiliating, as the projects not being used will be available for fairs requesting additional allocations through the formal appeals process.
