The IMTI diploma course for AMI 12-18 training was a transformative experience that grounded me in adolescent needs and characteristics, reinforced Montessori theory and best practice, and connected me to an amazing cohort of adolescent practitioners. I left the program thoroughly prepared to set a five-year plan for our adolescent program in motion and continue to benefit from the depth and richness of resources and experience provided.

The AMI 12-18 Diploma Course has been the most inspirational and transformative experience of my adult life. The summer residential experience was beautiful, empowering, and grounding in so many amazing ways. The advisors and staff are so kind and knowledgeable, and the connections built with other trainees will last a lifetime. I cannot recommend this course highly enough!
