The Gifted Association of Missouri has sectional conferences and state conferences that support gifted students, teachers and parents. Vendors come from around the state with tables of items and free information. This organization keeps me updated on Missouri law and changes to that law that affect gifted students. Advocacy is a big part of the organization. Past conference materials are available as well.
