CNS is open daily from 8:30am - 5:00pm and is designed to offer flexibility for families. Most children attend the Morning Program (8:30am - 12:30pm) 5-days a week, and families can pick and choose between full-day or lunch-bunch options on a schedule and per-diem rate that works for you.

Morning Program
Time: 8:30- 12:30  
Annual Tuition: $15,725 (2026-2027)

Teachers provide a daily routine that affords the children the opportunity to investigate many materials, both independently and in teacher-directed projects. The morning begins with an extended period of free play that includes opportunities for children to explore independently or work in small groups. Activities include water or sand play, dramatic play, outdoor play, art/science projects, manipulatives, and large blocks. As the morning progresses, the children have a whole-group meeting, snack, and story time. Each class spends time outside every morning, weather-permitting.

​Summer at CNS is a relaxed time for children involving lots of outdoor play and nature exploration in our shady, breezy playground. The program runs for five weeks; parents may sign up for individual weeks, assuming space.
We welcome new families to participate in the summer program. It is a good opportunity for incoming children to become familiar with many of the daily routines, the teachers, and other children. Children often have an easier time managing the transition from home to school, and settling into the classroom in the fall after spending a few weeks at our summer program.
