Affiliated Fair Guidelines

Requirements for being an Society-Affiliate Fair

New affiliations

Before affiliating with ISEF or Broadcom MASTERS, fairs must have been in operation for at least one year in which they had a functioning Scientific Review Committee to review and approve student research. This requirement is to help ensure that new fairs are an effective and sustainable educational activity before becoming affiliated.  Fairs may appeal this one-year qualification in cases in which the leadership of the fair has experience or training associated with an affiliate fair.

General requirements

  • The fair must serve a geographic territory that is not covered by another affiliate fair, except in cases of state or national fairs.
  • The fair must operate under the ISEF Rules and Guidelines and ensure that students and teachers are aware of these requirements as they begin research projects. New fairs should have at least one year's experience with these Rules.
  • The Fair Director agrees to hold the Affiliated Fair by the given deadline in early April.

Fairs will be granted affiliation status based on meeting these requirements as well as the overall benefit the fair offers to the students and schools in the proposed territory.


New fairs should incorporate an identifiable region such as a county, state, or other geographic entity. Territory must be listed with as much detail as possible and should specify any areas or populations within the defined area that are excluded. These territories as defined may not overlap with the territory of an existing ISEF or Broadcom MASTERS-affiliated fair, except in the case of a state or national fair.

Affiliation fee

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. As stated above, 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 paid by the early October deadline 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.

If you feel that your science fair meets these requirements for affiliation, please contact:
