We are proud to be an AMI Recognized School – one of only eight such schools in Ontario and THE ONLY ONE in Aurora, serving Newmarket, Richmond Hill, King City and Stouffville areas! The AMI Recognition is is the highest accreditation granted by the Association Montessori Internationale (AMI) for schools practicing authentic Montessori methodology as established by Dr. Maria Montessori. It validates our commitment to Montessori education, as well as confirms that our school meets all the AMI criteria for quality Montessori environments that support the full development of a child.

The Association Montessori Internationale (AMI) was founded by Dr. Maria Montessori and her son Mario Montessori in 1929, in order to protect the integrity of her life’s work. The AMI continues to promote Dr. Maria Montessori’s work around the world.

In Canada, AMI is governed by Association Montessori Internationale (Canada).


Introduced originally by Dr. Maria Montessori over hundred years ago, the Montessori method complements children’s own ability to learn through sensorial exploration and self-discovery.

Dr. Montessori wanted her work to benefit the children around the world and she did not think to protect her work or trademark her name at that time. Since the name Montessori is not protected by trademark, sadly today, many schools simply use the term Montessori to mean an educational institution for young children even when they do not follow the Montessori method. This makes it difficult and confusing for parents to identify schools that provide quality, authentic Montessori education for children.

At the request of parents and Montessori schools, the AMI Certificate of Recognition and AMI Montessori Quality Assurance are two programs initiated and administered by AMI to help identify schools that provide quality Montessori environments and are committed to the principles of the Association Montessori Internationale. In Canada, these programs are administered by Association Montessori Internationale (Canada).


An AMI Recognized School is the highest accreditation granted by the Association Montessori Internationale (AMI) for schools practicing authentic Montessori methodology and principles as established by Dr. Maria Montessori. The AMI Recognition program has been offered in Canada since the 1980’s and in the United States since 1973. A school that is accredited by AMI is identified as An AMI Recognized School.

Since 1980, only 6 Montessori schools have received this highest standard of accreditation from AMI in Canada and Church Street Montessori is proud to be the ONLY AMI Recognized Montessori School serving the York Region – Aurora, Newmarket, King City, Richmond Hill and Stouffville areas.

AMI Quality Assurance Program is not a form of accreditation. It is a voluntary program that is open for all Montessori schools in Canada. While it is not a form of accreditation, it is a commitment by a school to strive for excellence in Montessori programs for children by adhering to the AMI principles and practices.

AMI Quality Assurance was established in School Year 2013-2014 to help differentiate those schools that are committed to providing authentic and quality Montessori environments but may NOT yet meet all the AMI Recognition criteria. Schools that are participating in this program are identified as member schools. Church Street Montessori was one of the first schools to obtain member status when the program was initiated in School Year 2013 – 2014.
