Other member teacher-training courses

All Montessori training centers with a permanent, established, center are invited to become members.

Distance Learning

Due to many complaints about the quality of education gained in this method, by people who have taken distance learning courses, and the administrators who have hired teachers trained in this method, we can no longer recommend this kind of training. Time and money might be better spend reading books, researching on the internet, concentration on learning to observe children in a variety of situations, and meeting their needs.

NOTE: INTERNATIONAL COURSES: Montessori organizations in one country often offer conferences, workshops, and teacher training courses in other countries. Be sure to check all of the continent links on this site for information.

All Montessori organizations and teacher training centers are welcome to become members of The International Montessori Index.
