In psychology, the four stages of competence relate to the psychological states involved in the process of progressing from incompetence to competence in a skill:
The individual neither understands or knows how to do something, nor recognizes the deficit or has a desire to address it.
Though the individual does not understand or know how to do something, he or she does recognize the deficit, without yet addressing it.
The individual understands or knows how to do something. However, demonstrating the skill or knowledge requires a great deal of consciousness or concentration.
The individual has had so much practice with a skill that it becomes “second nature” and can be performed easily (often without concentrating too deeply). He or she can also teach it to others.
