The Association Montessori Internationale affiliates training centres throughout the world. These centres offer AMI diploma courses that are recognised internationally for their quality and authenticity.
The courses offered by the Association Montessori Internationale prepare adults to work with children at the following levels:

Assistants to Infancy (0-3)
Primary (3-6)
Elementary (6-12)
Erd Kinder (12-18)

Work is underway to document the current body of knowledge relating to Montessori education for the 12-18 year age group and an Orientation programme for teachers (in collaboration with NAMTA) is available.

Each year thousands of teachers and classroom assistants are trained worldwide.
All training centres are staffed by highly qualified AMI teacher trainers supported by a pedagogical team of experienced advisors to ensure that the objectives of Maria Montessori’s pedagogical principles are upheld. Students are examined by external examiners appointed by AMI, the role of which also serves to maintain the high standard and integrity of AMI course programmes.

The AMI diploma is respected worldwide as a representation of achievement in a teacher-training program of quality, integrity, and authenticity and is earned through successful completion of an intensive training program conducted by an AMI trainer. These dedicated master teachers have participated in a rigorous Training of Trainers Program and possess in-depth knowledge and understanding of Montessori principles and applications. Most are also consultants and lecturers for Montessori events worldwide. The comprehensive training includes educational theory and child developmental psychology, classroom observation, practice teaching, and material preparation. All AMI training courses must meet rigorous standards both in content and teaching staff.

An AMI diploma can lead to a career as a teacher at Montessori private and public schools around the world, a Montessori school administrator or owner, or an AMI consultant or trainer.
Options for undergraduate and graduate credit are available through colleges and universities affiliated with individual AMI training centers.
