Elementary GT service is based on a General Intellectual Abilities model. The elementary GT program, Challenge, is a one-day-per-week-pull-out-model for identified students in grades 1-5. Challenge students leave the regular classroom one day per week to work with the Challenge teacher, who is highly trained in the education of the gifted. Challenge curriculum includes high-interest advanced content, creative and critical thinking skills, research and technology skills, and the opportunity to pursue topics of individual interest. Each year's curriculum units are connected by a broad-based theme. The Challenge program is provided for identified students at all ​elementary ca​m​puses.
