Normalization in Montessori education refers to the process by which children, through engaging in meaningful work of their own choice, reach a state of concentration, inner discipline, and peace. This concept, introduced by Dr. Maria Montessori, describes the transformation observed in children when they are deeply absorbed in their activities. Characteristics of normalization include sustained focus, a strong sense of order, intrinsic motivation, and a joyful engagement in learning tasks.

Normalization is achieved in a well-prepared Montessori environment that offers a range of developmentally appropriate materials and activities. Through repeated, self-chosen work, children develop self-discipline, independence, and a love of learning. This state is considered an indication of healthy development and optimal learning conditions, where children are free to explore their interests and potentials fully.
