The Center for Gifted Education at The College of William and Mary, a research and development center, was established in 1988 under the direction of Dr. Joyce VanTassel-Baska. The center provides services to educators, policy makers, graduate students, researchers, parents, and students in support of the needs of gifted and talented individuals. Located in Williamsburg, VA, the center has established a national reputation for excellence in research, curriculum development, and service. Several major grants, including funding from the Jacob K. Javits Gifted and Talented Students Education Act, have provided significant support for the work of the Center.
