Conscious Competence Learning Model
In psychology, the four stages of competence, or the
"conscious competence" learning model, relates to the
psychological states involved in the process of progressing from
incompetence to competence in a skill.
Initially described as “Four Stages for Learning Any New Skill”, the theory was developed at the Gordon Training International by its employee Noel Burch in the 1970s. It has since been frequently attributed to Abraham Maslow, although the model does not appear in his major works.
The Four Stages of Learning provides a model for learning. It suggests that individuals are initially unaware of how little they know, or unconscious of their incompetence. As they recognise their incompetence, they consciously acquire a skill, then consciously use that skill. Eventually, the skill can be done without consciously being thought through, and the individual is said to have unconscious competence. 
Several elements, including helping someone 'know what they don't know' or recognize a blind spot, can be compared to some elements of a Johari window, although Johari deals with self-awareness, while the four stages of competence deals with learning stages.
The Four Stages
The individual does not understand or know how to do something and does not necessarily recognize the deficit. They may deny the usefulness of the skill. The individual must recognize their own incompetence, and the value of the new skill, before moving on to the next stage. The length of time an individual spends in this stage depends on the strength of the stimulus to learn.
Though the individual does not understand or know how to do something, he or she does recognize the deficit, as well as the value of a new skill in addressing the deficit. The making of mistakes can be integral to the learning process at this stage.
The individual understands or knows how to do something. However, demonstrating the skill or knowledge requires concentration. It may be broken down into steps, and there is heavy conscious involvement in executing the new skill.
The individual has had so much practice with a skill that it has become "second nature" and can be performed easily. As a result, the skill can be performed while executing another task. The individual may be able to teach it to others, depending upon how and when it was learned.
The model is expanded by some users to include a fifth stage,
which is not part of the original model from Gordon Training
International. The exact composition of this stage varies
between authors. Some refer to reflective ability, or "conscious
competence of unconscious competence", as being the fifth stage,
while others use the fifth stage to indicate complacency.
