@goforth:
That is a very thoughtful post. With admissions, you are dead spot on, it really depends on the school and the area as well, a music school might have a very, very competitive let’s say flute program, while its violin program might be a wider range. Generally, the more teachers a school has in a particular area, the wider the range IME. There is a range of ability at any school, of course, the more competitive a school is, the less the range, and you also can have a couple of top studios, then there is a major drop off with the other ones. Likewise, within a studio you can have a range, from the superstar student who is already out there, to the diamond in the rough.
Which means you are correct, @goforth, you could have a kid who would be considered unacceptably mediocre by let’s say the teacher in the ‘top’ studio, whereas another teacher sees something in the kid. With my mediocre comment, though, I was thinking more along the lines that the kid auditioning technically might be above some mythical “pass line” .
So okay, what does this mean? That in the end, there are a lot of factors here. My post #8 was that strong academics won’t bail out a kid whose playing is mediocre (whereas strong playing can override so-so academics when you are talking a program in university), that was my prime point. Your model A, @goforth, applies more to the highly competive programs,like a Juilliard or Curtis, where because of their name and reputation, they are like the ivies, they get so many applications they can pick and choose among ‘the best’ (though even there, what a teacher is looking for might not necessarily be the kid who has won X competitions, plays paganini at lightening speed and so forth). In the end, it is why people will answer “can I get admitted” with the line “it is something of a crapshoot”, because the selection process is not scientific, what teachers are looking for is not standard, what one teacher thinks is great might be another teacher’s nightmare…I will add, though, that while the range does vary, to use the violin as an example, if someone’s technique is mediocre (not just in comparison, but has sloppy intonation, sloppy bow arm, etc), few teachers would see them as a diamond in the rough, usually what happens IME (and again, using the violin, since I know that a bit) is a kid may not be as technically sharp by a certain order of degree from the ‘stars’, but shows something else with musicality and artistry (and often those two elements are on other sides of each other, a lot of the technically astute aren’t as sharp musically or artistically, whereas often kids who are musical and such are not as sharp technically IME).
The reality is where that line is is so murky, that it never hurts to try IMO, saying “I won’t audition there, because I am not good enough” may be self defeating.
