CGMS is a new Montessori teacher training program intended to make Montessori teacher education more effective and more accessible. Designed by well-respected Montessorians Kitty Bravo, Tim Seldin and Jonathan Wolff, the CGMS course of study uses cutting-edge distance-learning technologies to reduce the amount of time students have to spend physically at training centers. These same technologies also allow students to collaborate more effectively, and review Montessori theory and practice more thoroughly and with greater repetition over time.
