In terms of the guitar lessons I provide I've been asked to define my meaning of "Intermediate Standard". 

Well, if you've ever had to sit music examinations you will probably know what "intermediate" means, or have a fair idea about it. But for the type of tuition I provide I think the only way to try to define it is to suggest you try playing something like Andrew York's "Squares Suspended", note perfect with good intonation, (traditional music notation is available on his website http://www.andrewyork.net/SheetMusic/Wovenharmony.php) - or maybe the John Williams version of Cavatina, again note perfect and with good intonation, and from start to finish. I would say that anyone who can do so has reached the very peak of "intermediate" standard. That said no two people are alike so even this test is debatable, but at least it gives an idea as to the expectations of anyone taking lessons with me. How long it would take to reach that standard will, of course depend on the level of your capability when you start your lessons with me. 

As I have said in the pages of my website I always like to have a preliminary get together with anyone who is beyond the level of absolute beginner to review their level of competence and discuss what they want to achieve as a player so any doubts as to ability can be addressed at that time.
