Issaquah Montessori School has both toddler and primary programs. Children may begin in the toddler program at 15 months of age, and then move to the primary program when ready socially, emotionally and developmentally. This transition is different for each child, and handled with care by the teaching staff in both programs. The primary program extends through the kindergarten year, graduates are ready to begin first grade. A typical school day begins at 8:30am and ends at 3:30pm.
