“I am thankful that COA has intentionally cultivated such a community and strength to deliver the best education so that these kiddos are free to be themselves! Thank you, COA, for pouring [your hearts] into the future generations. We will be returning!”
COA parent*“I have had some of the best teachers who take the time to show interest in their students. The teachers always keep you informed and make sure you are doing the best you can. The website is very easy to maneuver through and the schedule was great for a first-time online student. Thank you all for allowing me the opportunity to be a part of the K12 family.”
COA student**My son’s first grade year was A-mazing!! Mrs. Payne was great working with my son to tap into his full potential as a Special Education student with Autism. During this time, we even found out that his strength was in Math. We can’t wait to see what his new teacher has in store for him as a GenEd/Resource student in a few weeks.
