Patricia Benner published a book whose name is Novice to Expert in 1982 and at that book she mentioned 5 levels from novice to experts. These levels are; novice, advanced beginner, competent, proficient and the expert. All these levels and the book is about nursing but I want to share this short and funny video to you due to relating with expert and novices.
You can examine the definition of these levels from the link below if you want;
