Postconventional morality is the highest stage of morality in Kohlberg's model, in which individuals have developed their own personal set of ethics and morals that they use to drive their behavior. Most of the time, their ethics and morals agree with social norms, practices and laws, but there can be conflicts between what is socially acceptable and what an individual believes. According to postconventional morality, when these conflicts occur, the individual should stay true to their own ethics.
