Four stages of competence is a learning model that relates to the psychological states in the process of progression. According to the model, you move from unconscious incompetence to unconscious competence. The learner or the trainee passes through the four stages, starting from stage 1 'unconscious incompetence', and ends at stage 4 'unconscious competence'; it is very useful when you begin to learn a new subject area.

Stages of competence:

1) Unconscious incompetence: In this stage you do not know what you do not know. The individual neither understands nor knows how to do something. In this sage you can take more time, you don't realize that you are not competent. You always act as a fake person. Where you believe you are competent. The person is not aware of the existence or relevance of the skill area. They are not aware that they have a particular deficiency in the area concerned. The aim of teacher or trainer is to move the person into the 'conscious competence' stage, by demonstrating the skill or ability and in a way that benefit will bring to the person's effectiveness.

2) Conscious incompetence: In this stage you really do know how much you don't know. Though the individual doesn't understands nor know how to do something but they recognize the deficit. In this you realize that you are not as expert as you were thought you were. In this stage person becomes aware of the existence and relevance of the skill. The person realizes that by improving their skills and ability in this area their effectiveness will improve. A person makes commitment to learn and practice the new skill, and to move to the 'conscious competence' stage.

3) Conscious competence: In this stage you know stuff, but you have to really think about it to act on it correctly. The individual understands or knows how to do something, but to demonstrate it requires consciousness or concentration. The person will achieve 'conscious competence' in a skill when they can perform reliably at their own will. The person needs concentration in this stage to perform the skill. In this stage person will demonstrate their skills but unable to teach that to other people. The person needs to practice a lot because practice is the single most effective way to move from stage 3 to 4.

4) Unconscious competence: In this stage you know stuff and you no longer have to think about it. You just do it. The individual has so much of practice that they can do without thinking, you just know what you want to do and it become 'second nature'. You can do multiple skills together. You can teach others also.

Every person brain personality types favor certain skills; every person has different nature and possesses different skills. So some person will pass the stage one and go ahead and some will not, same some will passes 3rd stage and go to 4th but some will not... Individuals develop competence only after they recognize the relevance of their own incompetence in the skill concerned areas. In this four stages of learning one more 5th stage is going to be added soon as many suggestion and research has been done to add it.
