My son spent two years at WCNS and my daughter is in her first year there. While I was originally worried about the "play-based" philosophy and thought that my children should be more focused on learning reading and math, I now realize that WCNS's focus on self-confidence, independence, and respect for others is really what children should be focused on at this age. My son left the school beginning to read and write, but more importantly, he was now comfortable in his own skin and able to navigate the classroom. The co-op experience requires more of a time commitment, but it allows you to see how your children and others are progressing and really helps build the community. Since you are there helping you feel like you have a better platform through which to advocate for your child.
I had one child go to WCNS and is now in the 2nd grade and my last child will be entering Kindergarten in September. The teachers are wonderful and the director is great. I had a chance to go to another preschool (they already had my first tution payment) but decided that WCNS was the way to go with my children. I love the co-op you get to know all the children in your childs class and you get to see your child in action with their teacher. Their classrooms are really big for the children to move around and I would recommend the school to all. Go take a tour and see for your self!!!
