We have been at this school for 2 years and love it. Our daughter is excelling in all subjects. She has a love for learning and looks forward to going to school every day. The teachers and staff go above and beyond for the students. Highly recommended!

We relocated here from up north. Schools in general are quite different in NC. We started out at the school that was in our neighborhood and that experience was awful. We then had to make a decision on what to do for our children's education and safety. We went on a tour at UDS and my husband and I both felt it was going to be a good fit. We are now so happy with our choice. Our children are both learning and developing. We are also very pleased with the communication on the teachers’ behalf. The school is still newer, and the staff seems to really care about the kids. I would say the only negative thing is that the property where it's located has no fields or gymnasium for the kids which I thought was strange. But as far as Education we are pleased.

We love this school especially the teachers.

We wanted to love this school but the past year was a complete disaster... it's disorganized, poorly run, and the leadership of the school and the UDS Parents Association treats everyone with apathy and disdain... unless you want your child to be a drone and receive a mediocre education at best, Union Day Charter School / UDS is not the place to go... it''s probably one of the worst schools in Union County and it is years away from achieving any meaningful improvement.
