| School History
CDS was born in 1962 as the first Montessori preschool in St. Louis. The innovative sprit required to create a new community based on a relatively unknown educational philosophy — in the midst of a world in great flux — required originality, creativity, and tenacity.
The same characteristics that define our beginnings continue to inspire us as we educate students from Toddler through Sixth Grade, preparing them for a world that demands of its most productive and successful minds an ever-evolving, rich set of skills and experiences. CDS’s robust start-to-finish education produces exceptional students of remarkable character who attend the secondary schools of their choice and lead meaningful adult lives in communities all over the world.

CDS Sixth Grade Secondary School Placement
| Secondary School Placement
Our start-to-finish premier preparation yields graduates who are highly sought after by area secondary schools. According to administrators at these schools, what makes a CDS student unique and coveted are the following characteristics:
- strong fundamental and 21st century skills
- high level of executive function
- well roundedness
- the ability to pick up on and absorb ideas/concepts that are introduced
All of the feedback we receive from area secondary schools indicates that we are preparing CDS students well to go on to the schools of their choosing — and that they are not only quickly fitting into these schools but leading others, too.
