SAVE SCHOOL

Long Island Montessori School provides a safe and loving environment for young children ages 3 to 6 that adheres to the principles and standards of the Montessori philosophy.

Long Island Montessori School is based on the whole child approach.

Your children spend each work period moving freely from one activity to another, guided by a Montessori-trained teacher and their own curiosity.

They are taught how to work and play harmoniously with others, developing social skills, in a relaxed environment.

Each step in this academic process reinforces a positive attitude, self-motivation, a growing self-confidence, and a life long love of learning.

Long Island Montessori School offers a first grade and a full day kindergarten program, allowing those children who are eligible to continue their quest for knowledge in a small group environment.
