Moral intelligence is newer and less studied than the more established cognitive, emotional and social intelligences, but has great potential to improve our understanding of learning and behavior. Moral intelligence refers to the ability to apply ethical principles to personal goals, values and actions. The construct of moral intelligence consists of four competencies related to integrity, three to responsibility, two to forgiveness, and one to compassion. Morally intelligent leaders and teachers in schools will be supporting, respecting and caring, and engendering those qualities in their students. This paper will explore what moral intelligence looks like and how it can be taught to leaders, teachers and children. Its relationship to character and ethical behavior, as well as the other intelligences will be discussed. By developing greater moral intelligence, benefits to the schools and the society will result in organizations that are more positive, improved relationships and students who are both smart and good and value universal human principles and rights.
