About TWIN CITIES REGIONAL SCIENCE FAIRS

Twin Cities Regional Science Fairs (TCRSF) is an all-volunteer, donor-facing 501(c)(3) nonprofit based in Maple Grove, Minnesota that organizes regional science fairs and student research competitions for middle- and high-school students across the Twin Cities area. TCRSF administers three geographically defined affiliations to the International Science and Engineering Fair (ISEF) and regularly advances student projects to national-level competition; the organization maintains archives, annual programs and awards lists for recent fairs (including 2023–2025) and posts Fair operations and registration through its event registration portal. The organization serves nine metropolitan counties, operates with volunteer judges and board members, and sustains corporate and institutional partnerships (for example, awards sponsorship from STEM-sector companies) to fund prizes, awards, and student participation supports.
