The questions is one of opinion. There are hundreds of styles, perhaps thousands. what would be considered basic, intermediate, or advanced is very different from one style to another and one instructor to another. Personally I tend to teach all three together. I give my students basics they need, some intermediate technique and advanced technique to keep them interested and to get them a bit used to it. By the time they are really ready for the more advanced technique they are beginning to see the principles and concepts behind the technique. This seems to help them with their understanding of everything they have learned and how everything relates.
