Quality Standards

AMI pedagogical standards maintain the level of excellence that Maria Montessori envisioned. Established by the AMI Scientific Pedagogy Group, the standards insure that each school offers programs for their children that allow for their full intellectual, social, and psychological growth and that the approach is consistent with what is presented in AMI training courses worldwide.

The Teacher

There will be one AMI trained teacher at the appropriate age level in each class.

The Assistants

Each class may have one non-teaching assistant. Should it be necessary to have more than one aide, he/she should be a non-teaching aide and should assist the directress with her daily tasks.

The Materials

Each classroom must be equipped with a complete set of Montessori materials from an AMI approved manufacturer: Nienhuis , Gonzagarredi, Matsumoto Kagaku
