The four levels of consciousness are unconscious incompetent, unconscious competent, conscious incompetent and conscious competent. Noel Burch, an employee with Gordon Training International, developed the model of the four levels of consciousness in 1970 as a way to describe the psychological stages one goes through while learning a new skill.
This model is based on two key factors: awareness and skill level. The unconscious incompetent doesn't have a skill or know he needs it, while the unconsciously skilled isn't aware of the talent he possesses and its value. The consciously unskilled knows what he lacks, while the consciously skilled knows what he has and how to use it to achieve success.
