By far the worst elementary school, they do not help with children with special needs. They also allow bullying and they do absolutely nothing about it. Sick of this school. If I wasn’t forced to send my kids here by law my kids wouldn’t even be attending school.

My daughter is in kindergarten at costner and her teachers are mrs. Kukish and ms love. She loves her teachers where she doesnt want the school year to end. Mrs kukish goes extra miles to make sure your child is on the right track and they are so wonderful!! She not only has the best teacher she goes to the best school :)

All 3 of my kids have went to Costner and I think it is a great school all the way around. All of the teachers and staff are excellent and always willing to go the extra mile to help the children. I have nothing bad to say about the school at all.

I love Costner School. My daughters have received the best education here as well as teachers who are caring and make learning fun. They love this school. I cannot say anything bad about it, so why didn't I give 5 stars? Because I believe no matter how good you are, you can always improve somewhere and I know Costner staff always strives to constantly improve and that is what makes them the best elementary school in Gaston County.
