Mission Statement

OUR MISSION: To provide an individualized learning environment, based on the principles of Dr. Maria Montessori, that is designed to help students become independent, life-long learners who are academically grounded and socially confident about their place in the world. OUR VISION: Our vision is to build an environment that will help every student explore, communicate, work and perfect skills to their highest potential. We want each student to grow in self-esteem, be well-grounded in academics and joyful about learning. OUR VALUES: Northwest Montessori School maintains the standards of the Association Montessori Internationale while serving families in all income brackets and offering financial assistance to a minimum of 10% of our families. Northwest Montessori School is a supportive and inclusive community that believes all people benefit from diversity. We support the development of skills necessary for our students to participate fully in a diverse world by fostering empathy, acceptance, tolerance, and understanding and by reducing fear, hostility, prejudice, and discrimination.
