Our family absolutely loves Chesterfield Day School. Our son has been there the past three years and we couldn't be happier. He has flourished in the loving and caring environment that is CDS. The teachers really help the students to become independent which leads to confidence. We're looking forward to our other son starting in their pre-school program next year.

We are beyond impressed with Chesterfield Day School. Our daughter is a toddler at this amazing school, and we simply couldn't be happier. CDS has a number of truly great things going for it (a beautiful campus, fantastic teachers, talented faculty, admin and staff and excellent programs). We truly love being a part of the CDS community!

Our children (6th grade and 3rd) have been at Chesterfield Day School since they were toddlers. We drive 25 minutes each way to get them there and along the way pass several well-known private elementary schools. We choose CDS for the Montessori foundation that perfectly transitions into rigorous curriculum that meets our kids at their level. We could not be happier with the teachers - they are a talented, well educated, dedicated group who make learning joyful for every student. Being a part of the CDS community is the best decision that we could have made as evidenced daily in our children's'' academic accomplishments and individual confidence.

This is my family's 3rd year at CDS. We love it! CDS educates the whole child and incorporates many modes and methods of teaching and learning. The children learn to be independent and confident. The CDS community is friendly and welcoming. We know we made the right decision in choosing CDS!

CDS is a unique private school and one that is worth a look for anyone interested in strong academics, a welcoming community and a faculty that is beyond amazing. CDS is the only school I know of that transitions students from Montessori in second grade into a wonderful upper school program. Students at CDS are confident, kind and are academically in the top tier of independent school students in the nation. The program at CDS includes a strong math, science and language core as well as a MakerSpace that is very sharp. Other parts of their program such as PE, music and art are very strong. We love CDS and would recommend it highly!

My son has been attending Chesterfield Day School for the past two years and we love everything about it! From the warm community feel to the personalized education he receives, we could not be more pleased with our decision to send him to CDS. They truly do live up to their mission of excellence. Well done, CDS!
