At the high school, I've noticed that it varies year to year, possibly based on the ability level of the students who make it into wind ensemble in any given. In the typical years, they play level 4 pieces, i.e. Kahn (I swear my kids have to play it every second semester), with a a couple "reach" pieces that are level 5-6, i.e. Angels in the Architecture, Russian Christmas Music. Often the latter get thrown out there, my kids all excited to play something more interesting and then the director decides not to play it at the concert/festival because it is not ready. They tend to play higher level stuff at their extra curricular band.
