GCA's two main core competencies and strengths have been in the areas of support groups and social events for autistic adults/adults on the autism spectrum. GCA's support groups and social events take place in Greater Chattanooga and North Georgia. Because of GCA's partnership with the Autism Society of Georgia, social events take place once a month generally in the Metro Atlanta for autistic adults/young adults. All social events are family friendly.
Other program areas and areas of interest for GCA are the Southeast Adult Autism Symposium, Parents Outreach, Workshops, Presentations, Consulting, CAEC Partnership, and Employment.
