Beginner has an arbitrary meaning and for us here it depends on how the curriculum is set up. One can be a beginner meaning having just started and is working learning the fundamentals do the art. Many programs have their curriculum broken into beginner, intermediate, & advance blocks for learn. However one who has learned the fundamental of the Beginner material and is working on bettering that material is no longer a beginner they are an intermediate working to better the aspects of that part of the curriculum. If beginner is attributed to one's skill then I have returned to being a beginner on several things. Due to age, injuries I no longer have the same skill in somethings. I have beginners who can do things I can. No being a beginner has more to do with the amount of time and understanding one has on a subject than just the ability to do.
