Curriculum extension units: are thematic units that extend the essential curriculum to provide additional rigor and challenge and to engage students in grades 2 through 5 in advanced-level thinking, questioning, and research. Students are nominated for participation by teachers based on academic strengths as demonstrated on a variety of performance indicators. Selected students receive individual letters of invitation. While participating in these units, students receive instruction from the GT teacher approximately 2 hours a week. Parents can expect regular progress reports and a written evaluation at the conclusion of the unit.

Research investigations: offer the highest level of enrichment for students who demonstrate a sincere interest in a particular field of study and a willingness to pursue this interest at an advanced level over an extended period of time.
