I don't know if there is ever a consensus with guitar teachers... ;D
The problem with guitar is that it is almost never taught like any other instrument i.e. note reading, graduated studies and whatnot. Many players live without ever reading a note and they are fine with that. If you look on the more established guitar forums you will almost always see a running argument for or against note reading, whether or not to teach theory to beginners or even just if tab is the work of the devil :
The idea with my book was that I wanted to have a method where I could define how time and rhythm works and give the student a physical framework to play time easier with all of the other things you have to do to make music happen on the guitar. And I have always thought that students (self taught or otherwise) should be playing music right off the bat so they should be learning rhythm guitar skills such as the basic types of chords (open, and movable shapes) and how to strum them in a pocket. And that they should be able to read at least a small amount of music...even if they never read another line of music ever again having had to learn to read at least one position on the instrument means that they can play time with single notes, they know what the notes that they are playing are called and they can mentally organize music in their head WHILE they are playing it.
That's quite a bit of stuff, but the guitar can be a pretty complicated instrument if you hope to give your students a start that they can apply to any style of music.
After (or even towards the end of) my book I usually have my students work through
Ross Boltons "Funk Guitar" book to get their 16th note mechanics happening (for both strumming and single note playing). Once again, even if they never want to play funk music after a month or so of working on this book they start seeing how much cleaner their playing is (you have to work on controlling the instrument with the left hand as much as strumming with the right) and how much better they play in time.
Another good "post Foundations" option is
Barrett Tagliarinos "Guitar Fretboard Workbook". This really gets the student learning their basic music theory not only intellectually but as it lays out on the instrument...you'll see many of my video lessons tend to follow his techniques ;D
Beyond that, it really depends on what the student wants to do with the guitar...and much of that is just learning the music in the style that they want to play. At this point the student understands the guitar, music theory and how to play the guitar well enough that we can learn music in their chosen "style of study" and analyze it...they can even self teach, to a point...
It never hurts to study with someone who is higher up the food chain, too...I don't get much time to take lessons myself but I am always trying to learn from the guys that I gig with or that I interact with online.
Playing with other musicians is also very useful...you can practice for years and after a certain point you will start losing skills and information. If you have to use it in a performance setting chances are that you will retain it better, and the stresses of preparing for performance will also push you to grow as well!
I hope this was helpful!!!
