I think thats a bit harsh. If Carl is an experienced teacher (or even if he isn't), it won't take him long to suss out modal scales, certainly enough to stay ahead of a grade 2 student. Being a good teacher doesn't necessarily mean having an encyclopaedic knowledge.
True - the construction of modal scales isn't difficult, but how about why they're important in jazz? Functional harmony and the construction of chords, the importance of the ii-V-I progression, analysing a chord sequence so you know what your scale choices are and why, voice leading, picking out guide tones etc
I should think you can teach grade 2 jazz clarinet without knowing any of that but you won't be able to begin to instil the understanding of why you're learning these elements that a good jazz teacher will - you'll just be teaching the bare minimum to get through the exam which is something I thought was generally agreed to be "not a good thing"
Why is it that the consensus of opinion on these boards seems to be that non-singers shouldn't teach singing, that recorder teachers should be recorder specialists (neither of which I disagree with), but that its perfectly acceptable for someone to teach jazz when they're only one page ahead of the person they're teaching?
