Prepare to support human development from birth to age three through deep study, observation, and hands-on practice.
The first three years of life are a period of extraordinary growth. Movement, language, relationships, and identity all begin here.
Montessori education recognizes this stage as foundational—not only for learning, but for becoming human.
This course prepares adults to meet that moment with knowledge, skill, and care.
The Assistants to Infancy Diploma is an AMI-recognized training that prepares adults to work with:
• Infants and toddlers (birth to age three)
• Families and caregivers
• Montessori schools and early childhood environments
• Community-based programs supporting early life
Grounded in observation and respect for development, the course brings together Montessori principles, scientific understanding, and practical application.
