Keep reading to find out!

What is AMS Montessori?

  • AMS Montessori is a school founded on the philosophy of Italian physician and educator Maria Montessori. AMS-certified schools are located throughout the United States and in over 60 other countries. AMS Montessori offers programs for children from toddlerhood through adolescence. AMS American Montessori Society is the largest Montessori organization in the world, with over 5,000 member schools.
  • AMS also provides professional development opportunities for educators, and advocates for public policy initiatives that support quality Montessori education. The AMS accreditation process ensures that schools meet high standards for curriculum, teacher training, and facilities. AMS-accredited schools are recognized as providing a quality Montessori education that prepares children for success in school and in life.

What is AMI Montessori?

AMI Association Montessori Internationale, or AMI, is an international organization that was founded in 1929 by Dr. Maria Montessori. AMI trains and accredits Montessori teachers and schools around the world. AMI is one of two organizations that offer this type of training (the other being AMS Montessori). AMI offers both elementary and secondary teacher training programs, as well as a program for school administrators. In addition to its work with teachers and schools, AMI also conducts research and advocates for Montessori education at the policy level.

Difference between AMS and AMI Montessori

  • AMS and AMI Montessori are two of the most widely recognized Montessori organizations in the world. While both AMS and AMI offer high-quality Montessori education, there are some key differences between the two groups. AMS is the American Montessori Society, a nonprofit organization that was founded in 1960. AMI is the Association Montessori Internationale, an international organization that was established in 1929.
  • AMS is focused on educating children in the United States, while AMI works to promote Montessori education around the globe. AMS offers teacher training and accreditation, while AMI provides teacher training and certification. Both organizations work to support Montessori schools and educators, but AMS and AMI each have their own unique approach to Montessori education.


Although both the AMS and AMI Montessori methods have their own benefits, we believe that the AMI Montessori approach is a better fit for most students. We hope this article has helped to clear up any confusion about the two approaches and given you a little more information to make an informed decision about what type of Montessori school is best for your child.
