What is AMS Montessori?

The AMS or American Montessori Society is a Montessori organisation based on American culture. Established in 1960, the AMS Montessori is headquartered in New York. It works for promoting Montessori methodology in private as well as public schools.

AMS Montessori methodology prevails throughout the United States. It has its own set of standards and rules for functioning. It does not follow the rules and regulations made by Maria Montessori. Nancy McCormick Rambusch, the founder of AMS, worked for AMI before establishing the American Unit. He came up with some new rules and regulations to be followed in AMS.

From the very start, Rambusch focused on taking forward the AMS methodology in American society into the 20th century. AMS wanted all its teachers to have a college degree so that the institution could be easily recognised by the state. It also allows the use of outside resources so that education could be diversified and be successful in building a child’s strong personality.

In addition, AMS provides Teacher education programs that educate people for becoming Montessori teachers. AMS methodology follows an advance and newer set of rules and regulations in a mindset to fit into the American culture. However, AMS Montessori methodology does not allow continuation if one changes school. Although one can easily learn to value morals here.

What is AMI Montessori?

The AMI or Association Montessori Internationale is yet another organisation for Montessori education, based in Amsterdam. It was established by Maria Montessori in 1929. It is headquartered in Amsterdam itself. Its main objective is to make Montessori education available worldwide.

Maria Montessori and her son, Mario, joined together to form the AMI Montessori methodology. During the period of formation, fascism grew increasingly in Germany, Spain and Italy. Due to this, Maria had to relocate her family from her long term home, Barcelona. Later in 1952, when Maria breathed her last, she handed over the legacy in AMI to her son. In 1954, AMI got registered by Dutch Royal Decree.

AMI consists of over 5000 members who work in 36 countries of the world. There are 64 AMI affiliated Teacher training centres. AMI holds an International Congress every four years. Several Montessori Associations from all over the world have come together to support this movement. The International Congress is held in a different country every year.

The methods adopted in AMI are standardised starting from the initial level of classrooms to the upper levels. A uniformity of teaching can be found, unlike AMS. If a student changes school, he/she will be eligible to get a continuation facility. All these features make AMI a wise option for Montessori education.
