Our Montessori training programs

CGMS offers four programs: Infant/Toddler, Early Childhood, Elementary and Professional Development

You can download our combined short brochure or click below on the one you are interested in for more information. You can also view samples of some of our videos.

Each program is offered in two tiers, either a Full Certificate or an Associate Certificate program. These are essentially the same programs, except that the Full Certificate program includes either one or two short residencies in addition to the online component. The Associate Certificate is not generally made available to North American Elementary students because of the increasing requirement of schools to have MACTE-accredited teachers.


The focus is more on understanding the incredible developmental changes that take place in the first three years of life.

Montessori teacher with student

Useful terminology

As you explore our training options, it may be helpful to define the following terms

Internship: time spent in an authentic Montessori classroom during your training. Normally this is done as an assistant to an experienced and trained Montessori teacher. A “self-directed” internship is a less common internship option in which student teachers are responsible for leading the class while they are still being trained.

Residency: time spent at one of our in-person training centers. The residency requirement is what distinguishes the Full from Associate certificates.
