The California Montessori Project recognizes that the role of the parent/guardian is paramount in developing civic values and ethical behavior in their children. Montessori curriculum is developed to encourage and support students in the further development of the civic values and ethical behaviors that support them to become responsible and caring citizens, family members, and workers within society.

Character education is interwoven throughout the educational program and fosters qualities such as: honesty, respect for self, others and property, morality (understanding what is right, legal and ethical), responsibility, human dignity, empathy, justice, civility, courage, and concern for the common good. CMP encourages all students to participate in community service projects to learn the importance of giving back to their community.
