According to him moral development of the child proceeds in sequential but distinctive stages. These stages are given below:

(a) Stage-I : In the early years of a child’s life (from zero-four years) the physical consequences of an action determines its goodness or badness. If fire burns the child, he does not touch it. The child is ego-centric and standards of morality are external here.

(b) Stage-II : The child gives importance to his own point of view, (his self) and is able to take account of other’s roles insofar as he can use them in his own way. This is a period of make belief. Right action is what which satisfies the needs of the child. The role of others is also important in the sense that a child does only what can bring approval of others. Thus, only that behaviour is moral which can satisfy not only self needs of the child but it must please others also.

(c) Stage-III : At this stage the child adopts the view pints of others on the basis of their consequences. He does not question the views of others. The child considers only that thing as right which are considered as right by others. Thus, the child is totally conformist to the standard of the society. 

(d) Stage-IV: At this stage, the child is able to make any moral decision on his own without caring for the thinking of others. Though he considers laws and regulations set by the society as the essence of morality, yet he develops his own principles of morality on various occasions. Thus, he is a non-conformist to the norms of the society to a great extent.

(e) Stage-V: Standards and norms are more internalized here. The adolescents examine various view points prepared by different societies and recognize them. They think that the laws prepared by their own society are correct. Other societies may have good moral principles that must be adopted after careful appraisal.

(f)Stage VI : This is the last stage of moral development according to Kohlberg. Here the universality of the view points of the individual is seen. He formulates his own universal moral principles which he thinks that all societies should adhere to it. True understanding of right and wrong is developed at this stage
