In the event that Mountain Shadows closes due to inclement weather or other emergencies, families will be notified through the following outlets:

  • Email and/or text
  • Facebook
  • Radio station: KOA (AM850)
  • Television stations: 2/13 (FOX), 4, 7, 9

Mountain Shadows will be closed due to inclement weather when BOTH St. Vrain and Boulder Valley school districts are closed. If only one of the area school districts closes, Mountains Shadows makes every effort to remain open. When the weather is poor, but Mountain Shadows remains open, classes will run as much as possible on a normal schedule. In rare cases, if there are few children or if a full staff is not available, classes may be grouped together or cancelled.

If necessary, arrive late to school, pick up your child early, or keep your child at home as conditions in your area dictate and please notify the school of your child’s absence.

Mountain Shadows Montessori School offers AMI programs for students 12 months to 12 years old.

...So, what is AMI?

Association Montessori Internationale

AMI is the organization that is tasked with the responsibility of maintaining the integrity of Maria Montessori's legacy. Mountain Shadows and AMI share a mission to support children's natural development and to help them become the transformative force of society.

This comes with a commitment to a standard of excellence, defined by...


Rigorous and extensive training

including the study of child development and a deep understanding of the Montessori materials to assist the teacher in creating the environment necessary for this work.


Three-year age ranges

within each classroom that allow children to work at their own pace and level of development.


Extended work time,

including a three hour uninterrupted work cycle.


Upholding international standards

through expert consultation every three years and regular and ongoing study of pedagogy and practice.

For your child, this means...


Whether it's digging in the dirt or discovering the universe.


Whether it's speaking your mind or learning to speak up.


Whether it's composing a song or coming up with a big idea.


Whether it's for ourselves or for others.


Whether it's work or play.

Critical Thinking

Whether it's studying science or solving a problem.


Whether it's doing your part or doing what's right.


Whether it's planning your day or preparing your own lunch.


Whether it's deciding together or sharing the work.


Whether it's supporting your friends or saving the planet.

This is what Mountain Shadows means for your child.
