Dr. Montessori first developed her educational approach while working with a preschool population. She gradually extended her approach to children and youth of all ages. Today, some Montessori schools provide all levels of learning, from infant & toddler though the secondary (high school) level. Others offer only certain levels.
The benefits of Montessori—the emphasis on independent learning, for example, and the warm, supportive community—continue to be important at each stage of development as children grow into lifelong learners and responsible citizens of the world.
