Article 9B (the state statute that outlines gifted education in NC) states that local LEA's must create a district AIG policy regarding identification, services, programming, etc. The program standards can be found on the "state level" page of this website.
The CHCCS district gifted policy is currently in the process of revision. A summary of the current district policy can be found here: https://sites.google.com/a/chccs.k12.nc.us/chapel-hill-carrboro-city-schools/academics/academic-programs/gifted-education/aig-services-in-a-nutshell.

On September 6, 2018, Jessica O’Donovan (Assistant Superintendent for Instructional Services) and Camille House (Coordinator for Gifted Services) presented an update on AIG services within CHCCS to the Board of Education.
