(1)Motor or Individual Stage (Birth to 2 year)
In this stage, motor habits assume a ritual character or he responds according to his own desires.
(2)Co-operative Stage : (2 to 7 years of age)
In this stage, the child’s play is with a disregard for rules.
(3)Codification of Rules Stage : (7 to 11 years of age)
In this stage, rules are respected though the notion of them is vague.
(4)Egocentric Stage : (11 to 12 years of age)
In this stage, the child observes the society’s rules, customs, etc.

In this way, Piaget classified the four stages.
The child proceeds from the mechanical, motor stage to the egocentric individual and then to the social stage of cognitive development.
In social co-operative stage, rules for very young are sacred realities, while they are matters of mutual agreement for grown-up youth.
For moral judgment of children, the social facts such as, constraint and unilateral respect is very important in the life of children. And for moral facts co-operation and mutual respect is very important for their development.
In this regard, Piaget wrote: "The sense of justice, though naturally capable of being reinforced by the precepts and the practical examples of the adult, is largely independent of these influences, and requires nothing more for its development than the mutual respect and solidarity which holds among children themselves."
In Piaget’s theory on moral development, we can observe that it distinguishes between the interonomus morality of younger children and the autonomous morality of older children. Piaget’s ideas on formal operational thought have implications for understanding adolescent’s moral development.
