Admissions Process

CMS accepts students throughout the school year based on available classroom space. Here’s how it works:


We encourage both parents to visit the school. When you visit, you will meet the director of admissions, tour the facility, and have an opportunity to observe children in their daily learning activities in the classroom. This is a good time to learn more about the Montessori teaching philosophy, and how attending CMS will benefit your child. For a more in-depth look at the calm and peaceful process of learning in a Montessori classroom, we encourage you to set up a time to observe.


Based on space availability, we accept applications throughout the year for immediate or future enrollment. Pending a review of the application, you will receive a letter of acceptance and an enrollment agreement; your child’s space will be reserved upon receipt of the signed enrollment agreement. If the program for your child’s age is full, your child may be placed on a wait list until a space becomes available. Click here for an application form.


Before your child starts school at CMS, we will contact you to set up a time for you and your child to visit. This provides an opportunity to meet the teacher and become familiar with the classroom, as well as to ease the transition. The Chesterfield Montessori School admits students of any race, color, national and ethnic origin to all the rights, privileges, programs and activities generally accorded or made available to students at the school. It does not discriminate on the basis of race, color, national and ethnic origin in administration of its educational policies, admissions policies, tuition assistance programs and any school-administered programs.

  • Thank you for your interest in our school!

    Chesterfield Montessori School reopened our physical campus this past June and we are thrilled to have children back at school. We have been hard at work implementing our new safety guidelines and procedures during this unprecedented time. We are seeing first-hand how beneficial it is for our students to be in an environment that is designed to meet their unique developmental needs, along with their classmates, highly trained teachers and other loving adults.

    Since we are an intimate community, we have flexibility to meet the children’s needs in a way that just isn’t available to large schools and systems. Our five acre main campus offers large, sunny classrooms with excellent ventilation, extra indoor space and plenty of outdoor space. Additionally, we have a seven acre Land Lab in Wildwood that is available to our older students. We are committed to offering individualized education for every child, designed to support your child’s unique individual needs by implementing the authentic Association Montessori Internationale method at every level.

    While data is showing that we can educate our youngest children safely at school, we have created a strong Distance Learning option and hybrid schedule for older children as necessary, and will offer child care for essential workers, including extended care hours. (Parents and their employers determine who is an essential worker.) Our health and safety protocols have been designed in collaboration with infectious disease experts in our area, as well as the local Department of Public Health.

    Please call us at (314) 469-7150 or email to find out more. We look forward to hearing from you and learning more about your family!
