Kohlberg's Stages of Moral Development: A Reference for Kidlit Writers
Kohlberg’s stages of moral development
A compact reference for stories that touch fairness, rules, loyalty, and conscience—without replacing your own ethical or developmental nuance.
Preconventional (Level 1)
Stage 1
Typical ages (from author notes): about 2–6
Description: Children judge whether an action is good or bad according to the consequences it will have for themselves.
Child’s voice (paraphrase): “I try to avoid punishment.”
Stage 2
Typical ages: about 5–8
Description: Children learn to conform to earn positive feedback or rewards.
Child’s voice (paraphrase): “I behave as asked, to be rewarded.”
Conventional (Level 2)
Stage 3
Typical ages: about 7–15
Description: Conventional morality begins when a child realizes there are conventions in society. Social rules and conventions become the authority for moral behavior. Children seek to preserve the rules of a group.
Child’s voice (paraphrase): “I am concerned with what people think of me.”
Stage 4
Typical ages: about 10–15
Description: The conventions that guide behavior expand to include those of the society in which the child lives. When examining whether an action is justified, the child considers whether it is consistent with the norms and laws of that society.
Child’s voice (paraphrase): “What would happen if everyone acted the way I did?”
Postconventional (Level 3)
Stage 5
Typical ages: 12+
Description: Morality extends beyond the frame of reference of any one society. Individuals feel as if they have freely entered into a contractual commitment with others, based on a desire for consensus and a rational assessment of mutual benefit from shared rules.
Stage 6
Description: Judgments of good and bad become influenced by universal moral principles. People at this stage agree that laws and societal values have validity, but if those laws conflict with principles of human dignity they hold internally, they will follow those principles.
Note (from author materials): Kohlberg estimated that only 20 to 25% of the adult population attains the postconventional level of morality.
