Immersive summer credentialing program for Montessori Teachers and Administrators

Welcome from the Director
Hilary Green

The Institute was founded in 1980 to address the extreme shortage of certified Montessori teachers, and to share the unique insights of two of Dr. Montessori’s closest collaborators, Dr. Claude Claremont and his wife, Francesca. Today, we offer Montessori teacher education programs leading to American Montessori Society (AMS) teacher certification.

The Institute is a center of innovative curriculum development. We are committed to an exceptionally high level of intellectual excellence in Montessori teacher education. We encourage students to explore new dimensions in Montessori education.

If teaching in a Montessori classroom is in your future, I encourage you to join us for your training. It is an inspiring way to spend your summer!


Through a partnership with Trinity Washington University in Washington, DC, Institute graduates may be granted academic credit in Trinity's Master of Arts in Teaching Program. By paying a nominal additional credit hour fee, adult learners admitted to Trinity's program may receive up to fifteen credit hours of graduate credits.

I don’t know if other training programs across the nation are this great. The care, attention, warmth, understanding smiles, etc., from the staff here has yet again increased my family pool. Thank you to everyone for your patience and guidance.

After completing three training levels the Institute offers, I feel I am exceptionally prepared to teach a variety of children. Each day brings a deeper understanding of the Montessori philosophy. The enriching environment provides students and teachers with up to date teaching methods and helpful classroom management techniques. 

I began my experiences with Montessori at the Institute in 1995. I have noticed that all the many facets have just gotten better. The program is constantly evolving. The trainers are all very knowledgeable about their subjects as well as very engaging with us, the students.

I was extremely impressed with the program – the quality of instructors, the content of the classes, the community spirit. I learned a lot this summer and am very pleased with the program as a whole.

Meeting so many other creative and helpful Montessori teachers has been a positive and valuable aspect of my training at the Institute. My classmates were very supportive and helpful of each other. The internship was also the most valuable – everything came together here, and as Dr. Montessori noted, hands-on experience is the way to go!

I love the way the instructors are so passionate and energetic about what they are teaching. They have all made a wonderful effort to present the materials and lessons in a hands-on and realistic way. I have gotten such wonderful ideas and extensions thanks to these teachers.

Meeting so many other creative and helpful Montessori teachers has been a positive and valuable aspect of my training at the Institute. 

I came to the Institute as a student for the Elementary training (6-12) after 17 years of teaching in a 3-6 environment. The Institute helped rekindle creativity in me: in making new and wonderful materials, in meeting each challenge in the classroom with fresh ideas. The support given by all staff members makes the Institute a warm and secure place for students to grow and develop.
